Chapter 1 — General Information
1-1 Introduction
This manual discusses the MA25101A IQ Streaming PCIe kit hardware and software installation and use of
the MX280006A IQ Acquisition Tool. The IQ Streaming PCIe kit has two main components:
•Windows compatible PCIe interface card that connects to Anritsu analyzers directly through a PCIe
interface port.
•MX280006A IQ Acquisition Tool (PC software) that interfaces to Anritsu analyzers via Ethernet or
through a PCIe interface.
This chapter covers general information, including references to related documents and system requirements.
Chapter 2 covers hardware and software installation. Chapter 3 covers the software overview and basic use of
the controls.
Before You Begin
Ensure that you are familiar with your analyzer by reviewing the “Additional Documentation” on page 1-4.
Also, there are several important points that need to be well understood to get full benefit from the
MX280006A IQ Acquisition Tool (PC software). The two main interface types are discussed below.
Using Ethernet
Connection speed matters. The supported analyzers have Gigabit Ethernet ports. This will provide gapless
streaming up to about 40 MHz at 8-bits, 20 MHz at 16-bits, or 10 MHz at 32-bits capture bandwidth. However,
if any element in the Ethernet chain runs at a lower speed, such as at 100 Megabits, then performance will be
seriously degraded. IQ Acquisition Tool cannot detect this, but it will be evident in data throughput. For best
performance, a direct connection is recommended, using a single Gigabit Ethernet hub or switch.
Using PCIe
PCIe is a system bus. The PC expects that devices on this bus are inside the PC case. It was not designed to
connect remote devices so care must be taken when making connections. First, when you power on the PC, it
interrogates the system bus for attached devices. The operating system expects that all devices on the system
bus will power on when power is applied to the bus.
It is important that the analyzer already be connected and running in the supported mode. If you turn on the
analyzer after the PC, it will not be found on the PCIe bus. Also, you would not consider opening the PC case
and removing the bus card while the PC is running. Turning off the analyzer is similar from the PC’s point of
view. Do not expect to power cycle the analyzer without also doing the same with the PC.
Note
Loading the FPGA Image for PCIe Streaming
When the MS2090A boots up, it does not automatically load the FPGA image that supports
PCIe data transfer. The analyzer detects when it is connected to an active PCIe card and will
prompt to load the image. If you choose to load the image, the analyzer will reboot, which takes
about 40 seconds. As discussed above, the PC must be started after the analyzer fully reboots
and begins sweeping. This means that the PC must also be powered up or rebooted after the
analyzer is set up properly, but not before the analyzer has finished booting.

1-1 Introduction General Information
1-2 PN: 10580-00476 Rev. B MA25101A UG
Best practice is always:
For power up:
1. Start by powering up the analyzer and wait for it to start sweeping.
2. If using an MS2090A with the MA25101A PCIe card, set the following:
•IQ Capture Mode: Streaming
•Output Port: Data Out
•Data Out Format: PCIe
3. Turn on the PC and launch the IQ Acquisition Tool.
For power down:
Turn off the PC, then turn off the analyzer.
Resource Management
When doing large bandwidth captures, you must make all resources available on the PC. The system bus is
fully utilized during the PCIe data transfer. If you play a game, browse the Internet, or edit a document, the
data stream will be interrupted and the transfer will stop.
Besides user programs, it is also necessary to limit system services and background programs running on the
PC. These can also periodically use system resources and interfere with data transfer. IQ Acquisition Tool
must write data at near the limit of the hard drive write speed. For example, if virus protection software is
checking this file for viruses during file writing, the process will be interrupted. IQ Acquisition Tool provides
means to disable many system services that are not necessary to the PC when using this software. It is highly
recommended that you use these tools to limit other background applications. Refer to Section 3-4 “Benchmark
and Optimize” on page 3-7.

Chapter 2 — Installation
2-1 Introduction
This chapter provides installation procedures for the PCIe card and both the PCIe card software driver and
user interface software. Be sure to read the ESD Caution below before starting Section 2-2 “PCIe Card
Installation”.
ESD Caution
The equipment discussed in this manual is susceptible to electrostatic discharge (ESD) damage. Operators
should exercise practices outlined within industry standards such as JEDEC-625 (EIA-625), MIL-HDBK-263,
and MIL-STD-1686, which pertain to ESD and ESDS devices, equipment, and practices. Because these apply
to the user’s PC and the analyzer, it is recommended that any static charges that may be present are
dissipated before disassembling the computer case or connecting cables or antennas to the analyzer. It is
important to remember that the operator may carry a static charge that can cause damage and these charges
should be dissipated through proper grounding. Following the practices outlined in the above standards will
ensure a safe environment for both personnel and equipment.

Chapter 3 — Software Operation and
Overview
3-1 Introduction
This chapter provides an overview of the Anritsu MX280006A IQ Acquisition Tool. It describes the software
features, general settings, and analyzer configuration. For detailed information on the analyzer’s user
interface and functions, refer to the analyzer’s user guide.
Using IQ Acquisition
The IQ Acquisition Tool is used for capturing streaming IQ data from supported Anritsu analyzers. It
currently supports the MS2090A and MS2710xA series analyzers and can stream IQ data from the Ethernet
port or to the MA25101A PCIe card.
1. Start by powering up the analyzer and wait for it to start sweeping.
2. If using an MS2090A with the MA25101A PCIe card, set the following:
•IQ Capture Mode: Streaming
•Output Port: Data Out
•Data Out Format: PCIe
3. Turn on the PC and launch the IQ Acquisition Tool.
Note
Loading the FPGA Image for PCIe Streaming
When the MS2090A boots up, it does not automatically load the FPGA image that supports
PCIe data transfer. The analyzer detects when it is connected to an active PCIe card and will
prompt to load the image. If you choose to load the image, the analyzer will reboot, which takes
about 40 seconds. As discussed above, the PC must be started after the analyzer fully reboots
and begins sweeping. This means that the PC must also be powered up or rebooted after the
analyzer is set up properly, but not before the analyzer has finished booting.

3-2 GUI Overview
This section illustrates the main graphical display and its controls, settings, and information. The main screen
is the primary setup panel for designating the capture characteristics. The user must specify some basic
analyzer setup parameters, the capture bandwidth, and data format. They also set the preamp and
attenuation states, and they designate a location for data to be stored on the local hard disk.
The PC software reads the following analyzer parameters (via Ethernet) and provides custom user settings if
desired:
•Set/Read Center Frequency
•Set/Read Reference Level
•Set/Read Span
•Set/Read Attenuation
•Set/Read Preamp state
•Set/Read Capture BW/Sample rate pair
•Set/Read Capture Bit depth (if user selects .xdat IQ file format, the bit depth is then fixed at I16, 16-bit
integer)
The PC software initiates IQ streaming on the analyzer when the Stream IQ Data toolbar button is clicked.
The software reads the IQ data stream over Ethernet or the PCIe interface and stores the data on the PC.
The IQ streaming and storage can be set to a fixed time or stopped at any time by clicking the Stop IQ Stream
button.

•Raw IQ (DGZ): This is the native format of the Anritsu SPA. For bit-depths < 32 bits, the I and Q values
are ordered in a proprietary way, and programs not specifically designed to support our DGZ files will
not be able to read these. Metadata is stored in an accompanying .dgzm file.
•Binary IQ (biq): This format undoes the I/Q pair ordering of Anritsu’s proprietary format. I/Q values are
written to the file in consecutive pairs. This file format is more easily read by 3rd party software. For
32-bit files, there is no difference. Metadata is written to an xml file.
Output Folder
This field sets the streamed data file and accompanying metadata file location where each filename is the time
stamp of the data stream. Network and external drives are not recommended.
Create Subfolder
If checked, a time stamped folder is created each time a new transfer is started. This is most useful if
Continuous Mode is on as then all related files are stored in a common location.

Output File
This is a display-only field of the current data transfer file name.
Run Length Control
Free Run: Streaming will continue until:
•The user presses “Stop”
•Out of space (transfer stops with about 2 GB remaining)
•An error is detected (If Stop on Errors is checked)
File Size: Streaming will continue until:
•The user presses “Stop”
•Out of space (transfer stops with about 2 GB remaining)
•An error is detected (If Stop on Errors is checked)
•The current file reaches the set file size and Continuous Mode is Off
•Continuous Mode is set to Off; the stream will end when the current file size limit is reached
Run Time: Streaming will continue until:
•The user presses “Stop”
•Out of space (transfer stops with about 2 GB remaining)
•An error is detected (If Stop on Errors is checked)
•The current stream time reaches the set time and Continuous Mode is Off
•Continuous Mode is set to Off; the stream will end when current file elapsed time reaches the set time
Status Information
At the bottom of the window there is status information. Stream status indicates if a stream is active or if the
stream stops because of an error. The four boxes in the status bar show: total bytes downloaded (reset for each
file in Continuous Mode), transfer rate, elapsed time, available disk space.

3-4 Benchmark and Optimize
Figure 3-5, “Transfer Optimization Dialog” is displayed when benchmark and optimize transfer parameters
button is pressed from the top toolbar.
The top section of this dialog shows system parameters and available resources. The three items on top right
will have green or red indicators depending on system settings. If the PCIe status is not green, then not all
performance tests will run, specifically the capture bandwidth tests. Best performance occurs when the system
isn’t busy with other tasks, indicated by the CPU Utilization.
Available Drives
This list will vary depending on the number of disk drives on the system. Only fixed drives should be used and,
if multiple drives are shown, then those that you want to test can be selected with the checkboxes to the left.
Capture Bandwidth
Shows the bandwidths that will be successful at gapless streaming for 16-bit and 32-bit captures. Note that
this is a measurement of the system at a point in time. If for some reason the system load is different when
actually transferring data, performance will be different.
Performance Test
Evaluates system performance. This will give the user a good idea of what they can expect when running an IQ
Stream. Note that for streaming data at relatively low bandwidth, such as anything below 50 MHz, much of
this discussion is irrelevant. To obtain the highest possible transfer rates, careful tuning may be required.
Blue Links
The blue links along the bottom are for controlling system services. Only the right-most link (Manage Services)
will be enabled unless the program is started with Administer privileges. Most services will not have a drastic
effect on IQ streaming, but cumulatively they may have a significant effect. IQ Acquisition Tool will stop the IQ
stream if a single byte is incorrect, even if it is 1 out of 10 billion. Services may periodically wake and request
access to system resources, causing the IQ stream to be momentarily interrupted. To avoid this, it is useful to
stop as many services as possible without making the PC unstable.
Stop ## Common Services
Stops services from a common list of safe services to stop. Stopping these services is safe assuming the PC is
dedicated to PCIe data transfer. If they are doing other tasks, an expected service may be missing. A PC is
likely to restart some services that it needs, so even after stopping them the count in the link text will likely
not go to ‘0’. Stopping Services with this function is temporary. All services will restart when the PC is
restarted.

Stop Custom Services
This will apply a list of services to stop. The list creation is the next link. Many PC’s will have varied set of
services running. Different virus protection software, for instance. The standard list will not include these.
Save Custom Service List
This creates a list, based on the current PC status, of services that have been stopped. This is most useful if the
user has used the ‘Manage Services’ link to stop services that are not included in the Common Services list.
Restore Services
This will restart all services that have been stopped. This is a way to restore the PC operation after IQ
streaming is complete.
Manage Services
This opens the standard Windows Services control panel application. This allows the user to select specific
services to stop, and also allows the user to permanently stop services of their choosing.
