2 Overview.
TLF3000 is a wideband, ultra-high dynamic range 2.4 GHz software-defined receiver, signal
analyzer and signal generator. It captures and analyzes the entire 2402-2480 MHz band
simultaneously. It can also generate arbitrary waveforms occupying the band 2395-2485
MHz with a maximum peak level of 0 dBm. Additionally, it includes a CW signal generator
covering 25MHz to 6GHz with an output level of -50 dBm to -28 dBm
Sapphire is a Bluetooth® 5 LE application for the TLF3000 software-defined receiver, signal
analyzer and signal generator. The Sapphire application can:
1. Perform all phy level tests as specified in Bluetooth Low Energy RF Phy Test
Specification (with minor restrictions). Testing beyond the limits of the specification is
also supported.
2. Act as a signal generator, creating all necessary signals for receiver testing including
signals outside the specification as well as supplemental data for AoA/AoD testing.
Signals as weak as -120 dBm can be generated for testing long range modes.
3. Act as a signal analyzer, performing transmitter tests on conducted or off-air signals
without knowledge of the payload format or hopping sequence. Test coverage
includes AoA/AoD supplemental data.
4. Generate advertising or scan request packets to provoke activity from items on a
production line and analyze the captured packets.
The application has been honed for speed. The ability to perform in-band emission tests
over the entire 2.4 GHz band in just a few milliseconds is particularly impressive. This is
possible due to TLF3000unique parallel architecture.
A key feature of the unit is its ability to perform C/I, receiver selectivity and intermodulation
tests without the need for additional test equipment. This is possible due to TLF3000 ultra-
linear wideband signal generator. This permits both wanted and interfering signals to be
generated through the same signal path. The high linearity and low noise floor ensure that
there is ample dynamic range to encompass both the wanted and interfering signals.
Furthermore, high fidelity filtering of the interfering signals ensures that they are correctly
bandlimited and that unwanted sidebands are not responsible for test failures; this is
frequently overlooked when external test equipment is used to provide these signals. The
single signal path also removes the need for time consuming and laborious calibration of
signal combiners as well as eliminating the need to ensure that the injected interfering and
wanted signals do not generate intermodulation products before arriving at the DUT.
Unique to TLF3000 is a 25 MHz to 6 GHz signal generator. This enables the majority of the
receiver blocking performance to be explored prior to committing the DUT for formal
inspection at a test house with its associated costs.

TELEDYNE LECROY
9 TLF3000 Sapphire Reference Manual V1.4
The Sapphire application is highly parameterised, permitting it to be configured for different
scenarios. For example:
1. The unit will function with arbitrary access addresses, allowing multiple devices to be
tested simultaneously without cross-talk.
2. The unit may be controlled directly from a host machine via USB or Ethernet, or
operated stand-alone with digital IO used to start, stop and report test results.
3. The DUT may be controlled directly from the unit or via a common host platform.
3 Control.
3.1 Overview
Sapphire can be controlled in three ways:
Control method
Interface
USB
Ethernet
Digital IO
Native language


Sapphire GUI


Standalone

Table 1: Methods of Controlling Sapphire
3.2 Native language
The TLF3000 supervisor program and Sapphire application can be controlled via a simple
native language. The native language provides a convenient means of controlling Sapphire
for high level host languages, such as Python. The native language exposes all the features
supported by Sapphire.
The native language relies on three control channels:
1. Command Control channel. Transfers commands from the host to Sapphire.
2. Command Response channel. Contains the response from Sapphire for the
command issued on the Command Control channel. There is one response for every
command issued.
3. Data channel. Transfers asynchronous data from Sapphire to the host.
If a USB interface is used, then these three channels map to three USB endpoints. If an
Ethernet interface is used, then the first two channels map to one TCP/IP socket whilst the
data channel maps to a second TCP/IP socket.
It is possible to utilise both the USB and Ethernet interfaces simultaneously.

TELEDYNE LECROY
10 TLF3000 Sapphire Reference Manual V1.4
3.3 Sapphire GUI
A GUI is shipped with the Sapphire application. This permits the application to be controlled
via a host running Windows, Linux or OS X. The GUI connects to the TLF3000 either over
USB or Ethernet. The GUI exposes the majority of the Sapphire functionality.
The GUI may also be used to generate test script files in a format which can be used by
native language programs.
3.4 Standalone
By placing the Sapphire image on a USB memory stick and attaching it to the TLF3000 USB
port, it is possible to run Sapphire without the need for a host computer. In this mode of
operation, the test script to be executed is contained on the USB memory stick. Control of
Sapphire is accomplished by toggling digital IO and pass/fail results are communicated back
by Sapphire setting digital IO.
4 Operating Modes.

Table 2: Sapphire operating modes overview.
4.2 Phy layer tester
The phy layer mode executes tests in accordance with the Bluetooth 5 LE RF Phy Test
Specification. The tests to be performed are entered into a script which is then executed by
Sapphire. The DUT is automatically controlled by Sapphire via a serial interface.
All tests are fully parameterised, permitting exploration of margin against the Bluetooth 5
specification or datasheet figures.
4.3 Signal Generator
The signal generator mode permits manual control over all the signal sources used in the
Bluetooth 5 LE RF Phy Test Specification. Any combination of the following signals can be
generated simultaneously:
1. Packetized LE test signal

TELEDYNE LECROY
11 TLF3000 Sapphire Reference Manual V1.4
2. Continuously modulated GFSK signal
3. In-band CW signal
4. Out-of-band CW signal.
All signal sources are fully parameterised.
4.4 Signal Analyzer
The signal analyzer mode monitors all 40 LE channel simultaneously. Any packets which
match a specified access address are captured and analyzed in accordance with the
Bluetooth 5 LE RF Phy Test Specification. Tests include the in-band emissions test, which
can be completed in as little as 2.5 ms.
If the captured packet is not a standard test packet, then an ‘off-air’ mode can be selected
which performs accurate approximations to the standard Bluetooth 5 LE RF tests but which
is agnostic to the packet payload. This permits RF test to be performed on live links.
The signal analyzer mode also permits the capture of raw IQ data.
4.5 Advertise/Scan
The advertise/scan mode permits RF testing of devices when there is no access to either
HCI or direct test mode. In this mode of operation, the DUT is provoked by Sapphire issuing
advertising or scan request packets. The sensitivity of the DUT can be deduced from the
signal level required to provoke a response, whilst the transmitter quality is ascertained by
analysing the packets sent by the DUT.
4.6 Standalone
The standalone mode permits Sapphire to be run without a USB or Ethernet connection. In
this mode of operation, the Sapphire image and test script are held on a memory stick which
is attached to the USB port of the TLF3000. The supervisor program on the TLF3000 will
automatically launch the Sapphire application which will then execute the test script held on
the memory stick. Control of the Sapphire application and signalling of pass/fail are
accomplished by the use of digital IO.
5 Launching the Sapphire GUI.
In order to communicate with the TLF3000 unit, it is necessary to attach it to a host computer
via USB or Ethernet (or both). An Ethernet connection is only possible if the host computer
and TLF3000 unit reside on the same subnet. The TLF3000 IP address can be changed by
connecting it to a host computer via USB and using the Application Loader.
To launch the Sapphire GUI it is first necessary to run Application Loader. This should result
in the following screen being displayed:

TELEDYNE LECROY

2. Serial number 00000078 connected via USB
3. Serial number 00000067 connected via Ethernet (this device is shown twice)
The right hand side of the window has three tabs:
1. Apps. Shows which applications are licensed to run on this unit. It also permits the
loading of new licence keys.
2. Network. Shows the current network settings and permits these to be modified.
3. Info. Provides more information about the unit and permits the unit’s friendly name to
be modified. It also provides a means of updating the firmware on the unit.
To launch the Sapphire application open the “Apps” tab and then either:
1. Double click on the Sapphire application
2. Highlight the Sapphire application and then click the “Run App” button.
On launching the application, the searching cursor should stall, the fan on the TLF3000 unit

6.2.6 Exit
6.3 Monitor panel
6.3.1 Overview
The purpose of the monitor panel is to permit the user to quickly ascertain whether:
1. There is RF energy being emitted from the unit
2. There is RF energy being received by the unit
Whenever the unit or DUT appears to be unable to receive, the monitor panel should always
be the first item to examine. Many problems can be quickly resolved with the information that
it displays.
The monitor panel also determines which RF port is being used and provides manual control
of the receiver front-end attenuation (not accessible in phy tester mode).
6.3.2 Output power
The output power gauge shows the energy being emitted by the TLF3000. The gauge is only
approximate and should not be used for accurate measurements.
The red arc indicates the overload region. If an overload does occur, this will be evident by
the ‘Output Power (dBm)’ label turning red and a warning message being displayed in the
status bar.
The output power gauge only shows the energy being emitted within the 2.4 GHz ISM band.
Energy from the out-of-band CW blocker is not included, even if its frequency lies within the
2.4 GHz ISM band.
6.3.3 Input power
The input power gauge shows the energy incident on the selected TLF3000 input port. The
gauge is only approximate and should not be used for accurate measurements.
The red arc indicates the overload region. If an overload does occur, this will be evident by
the ‘Input Power (dBm)’ label turning red and a warning message being displayed in the
status bar. It may be possible to remove a receiver overload condition by:
1. Adding additional receiver front-end attenuation using the control at the bottom of the
monitor panel (not accessible in phy tester mode)

TELEDYNE LECROY
17 TLF3000 Sapphire Reference Manual V1.4
2. Swapping to the ‘Tx/Rx’ RF port ff the ‘Monitor In’ RF port is being used. It is also
necessary to indicate which RF port is being used by setting the switch at the bottom
of the monitor panel.
The input power gauge only shows energy within the 2.4 GHz ISM band. F-bar filters at the
front of the receiver chain ensure other energy is eliminated and cannot block the receiver.
6.3.4 Input port
The input port switch selects which of the two RF input ports will be used:
1. The ‘Monitor In’ port is suitable for off-air monitoring and has a noise figure of 6 dB.
In benign environments no additional receiver front-end attenuation should be
required. However, in environments with strong Wi-Fi activity, it may be necessary to
add receiver front-end attenuation to prevent overload conditions.
2. The ‘Tx/Rx’ port is suitable for conducted measurements. If the DUT is capable of
outputting more than +10 dBm, it may be necessary to add receiver front-end
attenuation to prevent overloading the receiver.
6.3.5 Input attenuation
These controls are used to select the receiver front-end attenuation. The attenuation may be
adjusted by:
1. Moving the slider
2. Using the up/down arrows on the spin box
3. Typing a numeric value into the spin box text area
The available attenuation range is 0 to 31.5 dB in steps of 0.5 dB.
6.4 Status bar
6.4.1 Overview
The status bar at the bottom of the window is divided into three areas:
1. Overload indicator
2. DUT connection status
3. Error message text
6.4.2 Overload indicator
The overload indicator will turn red when an overload condition occurs on either the transmit
output or the selected receiver input port. The text of the message will indicate where the
overload condition is occurring.

TELEDYNE LECROY
18 TLF3000 Sapphire Reference Manual V1.4
6.4.3 DUT connection status
The DUT connection status message indicates whether the Sapphire application believes it
currently has communication with a DUT via a serial interface.
6.4.4 Error message text
The error message text reflects the last error detected by the Sapphire application running
on the TLF3000unit. This message is cleared when either the ‘Run’ or ‘Clear’ buttons are
pressed, or when a different operating mode is selected.
6.5 Mode tabs
The operating mode is selected by the tabs immediately underneath the tool bar. The
following operating modes can be selected:
1. Phy tester
2. Signal generator
3. Signal analyzer
4. Advertise/Scan
In addition, it is possible to display a page showing the health of the TLF3000 unit.
Whenever a new mode of operation is selected, any currently running tests are aborted.
6.6 Mode control panel
For each operating mode, a mode control panel is displayed to the left of the window. This
panel allows the user to define the parameters for the current operating mode. The contents
of the mode control panel are mode-specific.
In the case of the phy tester, signal analyzer and advertise/scan modes, the mode control
panel is divided into two tabs:
1. Collection. This tab contains parameters which determine what data will be collected
and how it will be collected.
2. Analysis. This tab contains parameters which determine how results from the
collected data will be displayed.
6.7 Graphics area
For the phy tester, signal analyzer and advertise/scan modes of operation, a graphical
representation of the results are displayed in the graphics area. Which results are displayed
and how they are displayed are determined by the settings in the “Analysis” tab on the mode
control panel.

TELEDYNE LECROY
19 TLF3000 Sapphire Reference Manual V1.4
For the signal generator mode, the graphics area provides a visual indication of which
signals have been programmed. Note that the graphics area only shows what has been
programmed; to make the programmed signals appear at the transmitter port, the ‘Play’
button within the tool bar must be activated.
6.8 Scripting/tabular results area
In the phy tester mode, the region below the graphics area is used for constructing and
displaying test scripts. This area also indicates whether the tests have been run, and if so,
whether they passed or failed.
In the signal analyzer and advertise/scan modes, the region below the graphics is used to
display tabular results. Which results are displayed is determined by settings on the
‘Analysis’ tab in the mode control panel. The results tables also contain test limits which can
be adjusted by the user. Tests that fail the limits are highlighted. The contents of the
graphics display area can also be controlled by highlighting rows within the results table.
The scripting/tabular results area is not used in signal generator mode.
7 Signal Generator Mode.
7.1 Overview
The signal generator is able to produce any combination of the following signals:
1. Packetized LE test signal
2. Continuously modulated GFSK signal
3. In-band CW signal
4. Out-of-band CW signal.
The mode control panel on the left hand side of the screen lists the signals which can be
generated. The switch to the left of the signal name programs the signal on or off. Although a
signal may be programmed on, no output is generated from the unit until the ‘Play’ button in
the tool bar is activated.
The top graph in the graphics window shows a symbolic representation of signals generated
within the 2.4 GHz ISM band. The graphics assume a resolution bandwidth of 100 kHz,
hence the displayed levels for modulated signals will be slightly lower than their programmed
levels. The LE channels are emphasised by alternating colour bars. Advertising channels are
further highlighted.
The bottom graph in the graphics window shows a symbolic representation of the signals
generated between DC and 6 GHz. The graphics assume a resolution bandwidth greater
than modulation bandwidth, hence all signals appear at their programmed levels.

7.3 Programming the packetized LE signal
7.3.1 Overview
Many of the parameters governing the packetized LE signal are programmable, however,
the access address is fixed at the test address of 0x71764129. If greater flexibility in defining
a packetized LE signal is required, then the user should use Tanzanite, a LE Traffic
Generator application compatible with TLF3000.
To turn the packetized LE signal on or off, toggle the switch to the left of the ‘Wanted’ text.
To program the packetized LE signal, expand the ‘Wanted’ signal menu by clicking on it:
