Recent innovations in test equipment design have created a new class of “smart
instruments” that give mobile phone manufacturers the ability to streamline
their production lines. The Agilent E6601A Wireless Communications Test Set,
which features an integrated PC with Windows®XP operating system, fits this
category. The E6601A test set has the control and interfacing capability needed
to become the centerpiece of a streamlined and automated test system. With an
embedded automated test program, the E6601A can significantly improve the
test speed, simplify the test system, and help reduce the cost of test.
For test engineers and programmers, this application note demonstrates how to
use the built-in capability of the E6601A test set to develop a simple program for
automated testing. The programming example includes setting up the program-
ming environment and the test set, verifying connectivity, creating a program-
ming flowchart, and writing the test program. Although several programming
environments can be used in this environment, the examples provided in this
application note are created in Visual Studio .NET®.

Introduction

The Agilent E6601A is a one-box test set for mobile phone manufacturing based
on a new platform. An important feature of this new platform is the embedded
PC, which runs the Windows XP Professional®operating system. Test
engineers and programmers now can work in a familiar computing environment
using a keyboard, mouse, and monitor connected to the test set. They can run
any current Windows-compatible program on the test set without having to
convert the code. Furthermore, they can make use of all Windows platform
features such as remote access.
A test set with a built-in PC has other advantages.
• Saves space – Placing a PC and monitor is always challenging on a production
line. Rarely does the rack have adequate space. By combining the PC and
monitor into the test set, the E6601 eliminates this headache. The front panel
can be controlled through automation, with a mouse, or by standard front-
panel buttons.
• Easy to deploy and maintain – An all-in-one solution makes moving and
deployment easy. As no external PC and accessories are needed, production
managers can rearrange or build new production lines more quickly. The test
set is easier to maintain, and there are fewer parts and connections to worry
about. Most regular maintenance, such as software upgrades and daily or
monthly alignment, can even be performed remotely by LAN.
• Helps reduce the expenses associated with buying and operating
equipment – The E6601A saves money by reducing the need for PCs, GPIB
devices and accessories, racks and floor space used for computers, and
computer maintenance costs. Test engineers and programmers also do not
have to use proprietary test development tools and can get started testing
more quickly.
Overview of the
E6601A Test Set

4
The E6601A has important features that simplify operating the test set and
automating the test environment. Foremost is the embedded Windows XP
computer, which shortens the user’s learning curve; allows remote control of
the test set and sharing of data between test sets; and allows online software
updating, troubleshooting, and support.
Connectivity features also help make the E6601A suitable for system integration
and remote control. Users can control and supervise a test procedure, communi-
cating by means of a LAN, GPIB, USB, or virtual LAN.
•LAN– LAN capability provides instrument connectivity over distances and
allows sequential sharing of instruments among multiple PCs. A LAN is the
recommended method of connecting instruments in new test systems. For the
E6601A, remote control over a LAN is an efficient way to implement remote
troubleshooting and monitoring.
• USB – Universal Serial Bus (USB) is a quick and easy way to connect
instruments to PCs on a bench top. Typically it is used to connect a single
instrument to a PC.
• GPIB – The General Purpose Interface Bus (GPIB) is a primary instrument IO
device with proven reliability. It is the most common interface for measurement
instruments and can be used in the integration of test systems.
• Virtual LAN – In embedded programs, the E6601A uses an internal LAN
interface to control the test set. In this scenario, the virtual LAN connects the
embedded PC and a test component internally.
Features That Simplify
Automation

5
Test programs can be developed using either the embedded PC or an external
PC. For best results, Agilent recommends developing and debugging test
programs on an external PC, then uploading the program into the E6601A’s
embedded PC for use in testing. The following instructions apply to test program
development on an external PC. Loading the program into the test set is
explained in a later section.
Set up the programming environment – Many programming environments can
be used with the E6601A, including C++, Visual Basic®, Agilent VEE Pro and
more. Today Visual Studio®is a popular tool for program development, so
the examples given in this application note use the Visual Studio .NET
environment and the Visual Basic programming language. You can learn more
about these programming tools at the Microsoft Web site
http://msdn.microsoft.com/vstudio/.
Install IO Libraries Suite – The IO Libraries Suite is an Agilent application for
connectivity. It needs to be installed when you plan to connect instruments to a
PC. The program helps you configure your system to control instruments from
the PC and to transfer data. You can download the suite software from the IO
Libraries Suite Web site: www.agilent.com/find/iolib. Under the Software
menu, select IO Libraries Suite and then IO Libraries Suite 14.1 (or above)
Product Download. After downloading, follow the installation instructions.
Connect and set up the test set – Different options are available for connecting
the external PC used for programming to the E6601A test set.
• GPIB connection
• Connect a GPIB cable from your computer's GPIB interface to the GPIB
connector on the test set's rear panel.
• On the test set’s front panel, under Screens, press the Config key.
• In the Configuration Main window, under Instrument Connections, type
the GPIB address you want.
• LAN connection
There are two ways to connect the PC and the E6601A over a LAN. One
method is to connect the PC to the E6601A directly using a cross-over
cable—in effect, setting up a small, PC-to-test-set-only LAN. The other
method is to connect the PC to the E6601A over an office or other existing
LAN or hub. In this case a regular LAN cable is used. Whichever approach
you choose, the following steps apply.
• Get the IP address of the E6601A
On the E6601A desktop, click Start, then select Run. A Run window pops
up. Input CMD in the command bar, then click OK. A black command
window is displayed. Type ipconfig after the flashing cursor and press the
Enter key. The Windows IP configuration is displayed. The IP address,
which is located under Ethernet Adapter Local Area Connection, is the
address for connection.
•On your computer, click on the Agilent IO Control icon in the taskbar and
select Agilent Connection Expert from the pop-up menu. When the Agilent
Connection Expert is launched, select E6601A in the LAN folder. Click the
Change Properties button, which is on the right side of the window. A
Change Configurable Properties of This LAN Device window is displayed.
Type in the IP address of the E6601A, which you located in the previous
step, and then click OK.
Developing a Test
Program

Verify the test connection – On your computer, click on the Agilent IO Control
icon in the taskbar and select Agilent Connection Expert from the pop-up menu.
When the Agilent Connection Expert is launched, instruments connected to the
external PC’s GPIB interfaces should appear automatically. Click on Refresh All
to update the list of instruments on these interfaces.
Now you can verify the test connection by sending some commands to the test
set. See Figure 1.
• Right-click on the test set you want to connect. In this example a LAN is used
to connect to an E6601A. In the pop-up menu, click Send Commands To This
Instrument. The Agilent Interactive IO program opens.
•InAgilent Interactive IO window, type a command—for example, “*IDN?”—
in the Command box. Then, click Send Command and the command will be
sent to the E6601A. Click Read Response and the IDN of the E6601A is
displayed in the Instrument Session History window.
• To close Agilent Interactive IO, click the Connect menu, and then click Exit.

Access the SCPI command documentation – Unique calibration applications
provide the E6601A test set with technology-specific transmitter and receiver
measurements for calibrating mobile phones. The programming examples in this
application note are based on a configuration for GSM/GPRS mobile phone
testing.
The SCPI command documentation for the E6831A GSM/GPRS Calibration
Application is contained in the GPIB Commands (GSM/GPRS CA) topic which is
part of the E6601A’s online help. This book contains syntax, descriptions,
ranges, *RST settings, test set requirements, and single-line examples of each
command provided in Visual Basic .NET using the VISA COM library. Another
tool for programming is the Agilent E6601A SCPI Discovery tool, which is used
in programming environments such as Visual Studio .NET. This tool makes
programming easy by providing fast access to the entire command structure and
by allowing you to drag the commands you need to the code. See Figure 2. For
more information on the SCPI Discovery tool, please refer to the E6601A Web
page at www.agilent.com/find/e6601a. More detailed use is available in the
built-in help system supplied with the tool.
Figure 2. Agilent E6601A SCPI Discovery is a useful programming tool used in popular environments
such as Visual Studio .NET.

A simple GSM test program is developed according to the programming flowchart
shown below in Figure 3.

Programming Details

Step 1. Reference the IO library – Start Visual Studio .NET and create a new
Visual Basic .NET application. In the Solution Explorer window, right-click
References and click Add Reference. See Figure 4.
Figure 4. Solution Explorer window in Visual Studio .NET.
In the Add Reference dialog box, click the COM tab and scroll down until you
see the VISA COM 3.0 Type Library component. See Figure 5.
Figure 5. Add Reference window in Visual Studio .NET.
Double-click on the VISA COM 3.0 Type Library entry to add the component, and
then click OK to close the Add Reference dialog box.

10
Step 2. Open the test set connection – Computers communicate with the
test set by sending and receiving messages over an interface. When you use the
Agilent VISA COM library in Visual Basic .NET, the FormattedIO488 object’s
WriteString, WriteNumber, WriteList, or WriteIEEEBlock methods are used for
sending commands and queries. To use the VISA COM library, you must first
open a connection to the test set using the ResourceManager object’s Open
method. After a query is sent, the response is read using the ReadString,
ReadNumber, ReadList, or ReadIEEEBlock methods.
The following Visual Basic .NET statements open the connection to the test set
and send a command to change the brightness of the test set’s display.
Option Explicit On
Option Strict On
Imports Ivi.Visa.Interop
Dim ResManager As New ResourceManager
Dim TestSet As New FormattedIO488
' Open the connection to the test set. Get the "VISA Address" from the
' Agilent Connection Expert (installed with Agilent IO Libraries Suite).
' In this sample, the "VISA Address" used for GPIB interface is
' "GPIB0::14::INSTR"
TestSet.IO = CType(ResManager.Open("GPIB0::14::INSTR"), IMessage)
'If it is a LAN interface, the “VISA Address” is
TestSet.IO = CType(ResManager.Open("TCPIP0::localhost::inst0::INSTR"),
IMessage)
' Send a command.
TestSet.WriteString("DISPlay:BRIGhtness MEDium")

11
Step 3. Initiate the interface and the test set – To ensure consistent,
repeatable performance, you need to start the program, your computer, and the
test set in a known state. Without correct initialization, your program may run
correctly in one instance but not in another. This variability could be due to
changes in the configuration of the test set made during previous program runs
or from the front panel.
If you are using the Agilent VISA COM library, you can use the resource session
object’s Clear method to clear the interface buffer. If you are using GPIB, the
resource session object’s Clear method also resets the test set's parser. The
parser is the program that reads the instructions sent to the test set.
• Fully presetting the test set – It is important to get the test set to a known
state before each production session. Sending the *RST command fully
presets the test set, which ends all current measurement processes and
restores all values to defaults.
• Clearing the test set's error queue – Before each production session, it is
useful to clear the error queue of any old messages. Clearing the error queue
assures that any messages logged are relevant to the current production
session.
The code in the example below fully presets and clears the error queue.
' Clear the interface buffer and reset the test set's parser.
TestSet.IO.Clear()
' Fully preset the test set.
TestSet.WriteString("*RST")
' Clear the test set's error queue.
TestSet.WriteString("*CLS")

12
Step 4. Set up general operating conditions – General operating conditions
include amplitude offsets and the display mode.
• Set the amplitude offsets – Amplitude offsets compensate for losses or gains
in the cables and fixtures between the test set and the mobile phone being
tested. Up to 100 frequencies can be assigned by using the command
SYSTem:CORRection.
• Set the display mode – For faster test execution, you can disable the front
panel display on the test set using the command DISPlay:MODE:TRACKing.
The following example shows how to set the amplitude offsets and display
mode.
' Set offset frequencies and set the state to On for the frequencies,
' offsets and RF IN/OUT Amplitude Offset State.
TestSet.WriteString("SYSTem:CORRection:SFRequency 1710.2
MHZ,1805.2 MHZ,1784.8 MHZ,1879.8 MHZ")
' Set offset values correcting for losses in dB.
TestSet.WriteString("SYSTem:CORRection -2.55,-3.12,-3.68,-4.23")
The following example shows how to set the test set's display mode.
' Turn the tracking mode to Off.
TestSet.WriteString("DISPlay:MODE:TRACking OFF")

13
Step 5. Configure the test set and wireless device parameters –
Different parameters are set for different measurements. However, most meas-
urements require settings for channel, power, and band. You will need to do the
following to configure the test set and mobile phone test parameters.
• Set up channels – Specify the channel associated with every band and then
set the active band.
• Set RF generator power – Set the output power of the test set.
• Set RF analyzer level – Set the expected input power level to the RF analyzer
and the uplink burst for single-slot measurements on dual-uplink PDTCHs.
• Set expected burst type – This parameter is used for measurement
synchronization.
The following example executes these actions:
• Setting the ARFCN for a number of different bands
• Setting the active band
• Setting the RF generator power
• Setting the RF analyzer level
***Configure Band and Channel parameters***
'
' Set the RF analyzer frequency control to auto.
TestSet.WriteString("RFANalyzer:CONTrol:FREQuency:AUTO:
GCALibration ON")
' Set ARFCN to 512 for the DCS band.
TestSet.WriteString("TRANsceiver:CHANnel:DCS 512")
' Set ARFCN to 5 for the EGSM band.
TestSet.WriteString("TRANsceiver:CHANnel:EGSM 5")
' Set ARFCN to 259 for the GSM450 band.
TestSet.WriteString("TRANsceiver:CHANnel:GSM450 259")
' Set active GSM/GPRS band.
TestSet.WriteString("TRANsceiver:BAND:GCALibration DCS")
' Set the RF Generator power state to on and the level to -70 dBm.
TestSet.WriteString("RFGenerator:POWer:GCALibration -70")
' Set the RF analyzer expected input power control mode to manual.
TestSet.WriteString("RFANalyzer:CONTrol:POWer:AUTO:
GCALibration ON")
' Set uplink burst 2 to be measured for single slot measurements.
TestSet.WriteString("RFANalyzer:BURSt 2")
' Set the Mobile Station TX Level for burst 1 in the DCS band to 10.
TestSet.WriteString("RFANalyzer:MS:TXLevel:DCS:BURSt1 10")
' Set the Mobile Station TX Level for burst 2 in the DCS band to 12.
TestSet.WriteString("RFANalyzer:MS:TXLevel:DCS:BURSt2 12")
' Set the test set to expect Training Sequence Code (TSC) 2 in the
' midamble burst.
TestSet.WriteString("RFANalyzer:BURSt:TYPE TSC2")

14
Step 6. Set up the measurement parameters – Two types of measurement
parameters must be set:
• Generic measurement parameters – Count, timeout, trigger
• Measurement-specific parameters – The setup configurations for a specific
measurement
The example below illustrates how to configure measurement or measurement
suite parameters.
' Configure Power and Modulation Quality Measurement Suite parameters.
' Set Power and Modulation Quality suite trigger arm to single.
TestSet.WriteString("SETup:PMODulation:CONTinuous OFF")
' Set Power and Modulation Quality suite multi-measurement count to 100.
TestSet.WriteString("SETup:PMODulation:COUNt 100")
' Set VISA timeout to 10 seconds. This timeout should be longer than the
' following measurement timeout value.
TestSet.IO.Timeout = 10000
' Set Power and Modulation Quality suite timeout to 5 seconds.
TestSet.WriteString("SETup:PMODulation:TIMeout 5S")
' Set the time offsets for the Power versus Time power measurement.
TestSet.WriteString("SETup:PMODulation:PVTime:TIME -28uS,-
10uS,321.2uS,552.8uS,570.8uS")
' Set the burst synchronization mode to Midamble.
TestSet.WriteString("SETup:PMODulation:SYNC MIDamble")
' Configure RF Channel Measurement Suite parameters.
' Set RF Channel suite trigger arm to single.
TestSet.WriteString("SETup:RFCHannel:CONTinuous OFF")
' Set the state to on and the multi-measurement count value to 150.
TestSet.WriteString("SETup:RFCHannel:COUNt 150")
' Set RF Channel suite timeout to 5 seconds.
TestSet.WriteString("SETup:RFCHannel:TIMeout 5S")
' Set RF Channel suite filter to 1 kHz.
TestSet.WriteString("SETup:RFCHannel:FILTer BWKHZ1")
' Set trigger delay time to 1.5 ms for the 1 kHz filter.
TestSet.WriteString("SETup:RFCHannel:TRIGger:DELay:BWKHZ1 1.5mS")

15
Step 7. Set up the measurement suites – A measurement suite contains a
collection of measurements that are all made using the same set of signal samples.
There are two ways to perform a measurement within a measurement suite:
SETup:<Measurement Suite>
INITiate:<Measurement Suite>, ...
FETCh results
and
INITiate:<Measurement Suite> <Measurement>, ...
FETCh results
Below are examples of how to configure measurement suites using these two
methods.
SETup:<Measurement Suite> method example
' Setup Initiate
TestSet.WriteString(“SETup:PMODulation:INITiate PFERror”)
'Initiate a phase and frequency error measurement.
TestSet.WriteString("INITiate:PMODulation")
' Fetch phase and frequency error results.
TestSet.WriteString("FETCh:PMODulation:PFERror?")
FetchPmodulationPferror = CType(TestSet.ReadList(), Array)
INITiate:<Measurement Suite> <Measurement>, ... method example
' Initiate a phase and frequency error measurement.
TestSet.WriteString("INITiate:PMODulation PFERror")
' Fetch phase and frequency error results.
TestSet.WriteString("FETCh:PMODulation:PFERror?")
FetchPmodulationPferror = CType(TestSet.ReadList(), Array)

16
Step 8. Make a connection – This step requires making a connection
between the test set and the mobile phone. Typically, you need to command the
phone to synchronize to the test set's signal and begin transmitting back an
appropriate signal. However, for the measurements in which signal decoding is not
performed—for example, Tx or Rx calibration—this synchronization may not be
necessary.
Step 9. Initiate and fetch measurement – This step is a continuation of the
measurement procedures described in Step 7.
Step 10. Re-configure the test set and wireless device connection
parameters – After performing a set of measurements on a mobile phone
using the configuration established in Step 5, you may want to change this
configuration and test the wireless device again. This step involves changing
testing conditions such as channel, wireless device transmit power level, and
cell power.
The following example changes the settings for a new band (using the ARFCN
that was set previously in Step 5) and sets a new uplink power control level for
the new band.
' Set active GSM/GPRS band to GSM450. This will use ARFCN 259 defined
' previously.
TestSet.WriteString("TRANsceiver:BAND:GCALibration GSM450")
' Set the traffic channel wireless device uplink power control
' level for the GSM450 band to 21.
TestSet.WriteString("RFANalyzer:MS:TXLevel:GSM450:BURSt1 21")
Step 11. End the connection – This step ends the transmission by the mobile
device. It usually includes three procedures:
• End the wireless device transmission – You must send the necessary test
mode commands to the mobile phone to end its transmission. These
commands are specific to the phone.
• Partially preset the test set – It is good practice to partially preset the test
set and stop all measurement processes without resetting all parameter
values to their defaults.
' Send this preset command to partially preset the test set without
' resetting the parameter values to defaults.
TestSet.WriteString("SYSTem:PRESet3")
• Close the connection to the test set – When your program no longer needs a
connection to the test set, it is important to close the connection using the
FormattedIO488 object’s Close method.
' Close IO interface to test set
TestSet.IO.Close()

17
Once a test program has been developed and debugged on the external PC, it is
loaded into the E6601A and the external PC can be disconnected. The transition
is simple. In the programming shown so far, all that really needs to be changed
is the resource descriptor for the test set.
In the example that uses the GPIB interface between the PC and test set, the
code reads:
TestSet.IO = CType(ResManager.Open("GPIB0::14::INSTR"), IMessage)
To run the same program internally, the Virtual LAN (as described earlier) should
be used. It can be done in two ways.
1. Hard coded, using the instrument name (for example, the instrument name
is E6601A0429):
TestSet.IO = CType(ResManager.Open("TCPIP0::E6601A0429::inst0::INSTR"),
IMessage)
2. Generic, which allows easier transport to other test sets:
TestSet.IO = CType(ResManager.Open("TCPIP0::localhost::inst0::INSTR"),
IMessage)
After changing the resource descriptor in the program, rebuild the .EXE and
move it to the E6601A (a USB flash drive is useful for this step) and run it as
before. Communication now takes place using the virtual LAN instead of the
GPIB connection used in the earlier examples.
As this example shows, writing a program to automate the E6601A test set is
straightforward using Windows-based programming tools. Setting up the
programming environment and the test set, verifying connectivity, creating a
programming flowchart, and writing the actual test program can all be
accomplished with relative ease. The program is then uploaded and run on the
E6601A’s internal PC. This powerful capability, when added to the E6601A’s
other time- and space-saving features, makes the test set a valuable addition to
a fast-paced, high throughput production line.
