The one test set for all your narrowbanding test needs!
With the largest selection of digital radio options of any radio test set,
the 3920B will meet all of your narrowbanding test needs, both now and
in the future. The software defined digital architecture of the 3920B
provides for future technology enhancements as new digital
technology becomes available. You can easily perform software updates
in the field, making additions of new software features and options as
simple as plugging in a USB flash memory drive.
Menu of Radio Test Systems in the 3920B
Ease of Use
Combining the power of an onboard PC with a 30 GB hard-drive and
Linux OS, the 3920B can support USB mouse and keyboard interface
for very easy operation as well as almost unlimited save/recall setups,
saving time and effort. Multiple methods of controlling the 3920B
include the front panel keys, using a mouse and keyboard, or through
a VNC application on your PC, touch-screen tablet or mobile phone.
Ease of Test
To make you more productive, the 3920B is not only simple to use but
has features that makes testing a radio quick and repeatable. The 3920B
features easy-to-read meters with Pass/Fail color coding for instant
Go/NoGo testing. With these easy-to-configure meters, you can set up
unique Pass/Fail parameters for each radio type that you are testing.
When used with the save/recall locations, this allows for instant recall of
the test parameters, so semi-technical or non-technical individuals can
simply key the radio and test. The meters will display “Green” for good,
“Red” for high and “Blue” for low. A quick glance and the operator will
know that the radio is within established test parameters.
High Performance
Measurement speed is directly related to processing power and
internal communications. The 3920B digital architecture utilizes a
mixture of powerful digital signal processors and programmable logic.
Coupled to the use of a compact PCI backplane capable of delivering
peak rates of >100 MB, this ensures that the instrument has the power
to acquire, synchronize and process data, producing measurement
results to the user with the minimum of delay.
Accurate Testing
Time Base: With a 0.01 ppm OCXO frequency standard, the 3920B
provides ultra-reliable RF frequency measurements. For even more
stability, the 3920B provides an external frequency reference input.
Generator: Level accuracy is important in determining today’s
receiver performance in design, manufacturing and field service
environments. With a 1 dB (0.6 dB typical) level accuracy on the RF
output ports, the 3920B provides consistent results in testing receiver
parameters.
Receiver: For sensitive measurement, e.g. off-air analysis, a low power
input is provided via the antenna input port. This low level input gives
the user the ability to measure an off the air signal as low as -100
dBm or -115 dBm with the internal pre-amp selected. Direct input of
signal power of up to 125 W is supported, making the 3920B
compatible with virtually all practical requirements for mobile
terminal and base station test.
Audio: With high accuracy audio generators from 1 mV to 8 V rms,
the 3920B provides level accuracy to ±1% of the setting. The audio
generator frequency ranges from 20 Hz to 40 kHz and 0.1 Hz resolution
provides solid audio performance for audio testing. The AF Counter
features full range from 20 Hz to 20 kHz.
Automatic Testing
The Auto-Test II environment provides you with the capability to turn
the 3920B into a stand alone ATE test environment. With the built-in
PC running your test script, or one of our available automatic test and
alignment applications, the 3920B can be conformed to your exact
testing needs. Available with the Auto-Test II option for the 3920B are
a selection of applications covering many of the latest digital radios.
With these applications, you can automatically test and align the
transmitter/receiver of a radio in as little as 5 minutes.

allows migration from the 8920B to the 3920B extremely easy.
Analog Duplex Screen
Full span spectrum analyzer: View signals from 1 MHz to 1 GHz
with the 3920B or to a full 2.7 GHz with the frequency extended option.
With a DANL of -140 dBm (300 Hz RBW with pre-amp enabled), the
3920B provides high performance spectrum analysis. This full band
analyzer provides plenty of range to view harmonics and other
spurious emissions in and out of band.
Remote Operation: Use of the 3920B Ethernet connection permits
remote operation from anywhere in the world making it possible to
download new software or remotely interrogate instrument status. With
an internal VNC server, users can install VNC software on their PC or
Tablet PC and remotely operate the front panel of the 3920B from
virtually anywhere on the planet. All that is needed is the ability to
access the unit’s IP address.
OPTIONAL TEST CAPABILITIES
Site Monitoring Application (390XOPT051)
The 3920B brings impressive new capabilities to site monitoring
applications. With option 392XOPT051, the user now has the ability
to leave the 3920B on-site while the unit provides automated data
logging of the site’s effective receiver sensitivity. When connected
to a good documented receiver (a “golden” radio), the 3920B will
automatically calculate the Effective Receiver Sensitivity (ERS) at
a predetermined interval (example: every 10 seconds) over a specified time (example: log ERS for 72 hours). As these measurements
are taken, a min/average/max SINAD is displayed, and the data is
logged to the 3920B’s internal hard-drive. Spectral information is also
optionally logged with each measurement to help locate and track
sources of interference. This gives the system engineer a valuable tool
in determining site location performance and system RF boundaries.
IQ Gen Modulation (390XOPT054)
IQCreator is an Aeroflex developed PC based software utility that
gives the user the ability to develop their own waveforms to use as
the modulation source. Since the waveforms are defined by I and Q,
virtually any type of complex digital modulation format can be
created. With the IQ Gen Modulation option, once the IQ waveform
is created it can easily be uploaded to the 3920B and used as the
modulation source in the Analog Duplex System.

demodulated RF signal. This feature allows users to view frequency
amplitude in relation to other audio frequencies and to isolate
problems such as noise in audio circuits. With a frequency range of
1 Hz to 24 kHz, the audio analyzer covers more than the full audio
frequency range of mobiles and hand-helds. In addition, there are
two markers, plus a peak hold and average function. The user can
also capture traces that can be stored and then recalled later for
use as a comparison with a live trace. A tracking generator option
(390XOPT210) is also available as an add-on to the audio analyzer.
Harmonics and Spurious
Tracking Generator (390XOPT061)
A full featured spectrum analyzer is available, standard, on all 3920Bs.

generator allows the user to look at the response of a duplexer, filter bank or other RF device on the spectrum analyzer. This option
greatly simplifies the often laborious process of checking or changing
the tuning of a duplexer. When used with the optional return loss
bridge (AC4105), the spectrum analyzer/tracking generator can
measure the return loss of an antenna or cable.
Audio Analyzer
2.7 GHz Frequency Range (392XOPT058)
The 3920B comes standard with a generate and receive frequency
range of 10 MHz (100 kHz usable) to 1.05 GHz. This option will
extend the range to 2.7 GHz.
Harmonics and Spurious (390XOPT060)
The ability to quickly and accurately measure the harmonics and
spurious of the transmitter of a radio is the function of 390XOPT060.
The fundamental frequency is automatically detected and measured and then the second and third harmonics are measured and
compared. In addition, the spurious signals that are higher than the
configured level are identified and displayed. The frequency and
level of the fundamental, as well as the harmonics and spurs, are then
displayed. This option makes finding the harmonics and spurious
transmitter very simple. Simply connect the transmitter of the radio
to the 3920B, key the radio and press Start.
Spectrum Analyzer with Tracking Generator
Power Between Markers (390XOPT064)
Also available as an option, the power between markers option
provides a measurement of the amount of power between the
spectrum analyzer markers. With this feature, the user can set the
position of two markers on the spectrum analyzer and then measure
the amount of power in the bandwidth selected with those markers.
This will enable the user to determine the amount of power in an
adjacent channel or in the center channel.

enable the user to test the capability of the mobile station to operate
correctly in the presence of this message. The purpose of this
message is to inform mobile stations of the presence and status of
sites adjacent to this particular site.
Secondary Control Channel Broadcast Message
(390XOPT215)
This option adds the secondary control channel broadcast message
to the control channel messages transmitted by the 3920B. This will
enable the user to test the capability of the mobile station to operate
correctly in the presence of this message. This message is used to
inform mobile stations of other control channels or other potential
backup control channels at this site.
One of the newest features of the 3920B is the capability to test P25
Phase II TDMA operation of both base stations and mobile stations.
With this option, the 3920B can measure and analyze the different
modulations used for both the outbound and inbound signals used
in P25 Phase II. With the modulation for Phase II being completely
different from the Phase 1 C4FM modulation; this option is critical

Call Processing Highlights
The 3920B can be freely configured to emulate a TETRA network
by selection of the appropriate channel plan, country code, network code, color code, etc. Once configured, registration, group
attachment and TETRA call types including group call, private call,
emergency call, telephone call and user defined call can all be tested.
SDS messages (types 1 to 4 and SDS-TL) can be sent or received.
The 3920B TETRA system option displays a range of mobile reported
information relating to registration, group attachment, test mode,
call type, called party, status messages, text messages and DTMF
digits dialed.
TETRA Test (TT) Protocol Support
The TETRA MS option provides support for the TETRA Test (TT)
protocol as defined in ETSI EN 300 394-1. The TT protocol allows
the mobile to be tested in a loopback mode whereby the mobiles BER,
MER and RBER can all be reported.
Audio Testing
Subjective audio testing is supported for simplex and duplex calls.
Audio spoken into the mobile’s microphone is received and stored by
the test set, which then re-transmits the speech so that it is replayed
through the mobile’s speaker or ear piece with 2 seconds delay added,
thus, providing an end-to-end audio quality test.
Direct Mode Functionality (390XOPT112)
The 3920B also supports the testing of Direct Mode Operation. The
3920B can initiate or receive calls from a mobile that is operating
in direct mode and then make transmitter measurements such as
power, frequency error and modulation accuracy. The operation and
graphical displays are very similar to the normal TETRA operation.
TETRA Energy Economy Mode (390XOPT114)
This optional mode of operation provides protocol signaling to
control a mobile’s energy economy mode from “Stay alive” through
energy groups EG1 (shortest sleep) to EG7 (longest sleep) and is
used in conjunction with the comprehensive signaling capabilities
already within the TETRA MS option. This operation enables
developers, operators and users to configure battery test scenarios to
simulate particular operational conditions. It gives them the testing
flexibility to characterize the expected battery life performance in its
intended operational use on the network.
Protocol History Maximized Tile
TETRA Test Mode T1 and T1 Loopback
The TETRA MS and TETRA BS options provides various T1 test
signals as defined in ETSI EN 300 394-1 for performing manual
testing of TETRA base station and mobile stations receivers. The
test signal T1 in the MS T1 application provides control information
to the mobile to aid testing, e.g. burst type, max, TX power, loopback
commands. These T1 test signals can be used by the mobile in a
test mode to output received demodulated data to a test interface for
external processing of receiver Bit Error Rate (BER). Alternatively,
the mobile can be commanded by the test signal T1 to loop back
the received data to the 3920B which can then perform BER/MER/
PUEM measurement. In the BS T1 application, the 3920B also
supports T1 loopback BER/MER/PUEM measurements for base
stations.
TEDS Test Operation (390XOPT117)
With the TEDS (TETRA Enhanced Data Service) testing operation,
the 3920B has the capability to test TEDS capable mobile stations.
The testing is performed by using the TEDS T4 test mode of operation. This enables the 3920B to make transmitter and receive performance measurements. These measurements include:
• Power
• Burst Timing
• RMS and Peak Vector Error
• Frequency Error
• IQ Imbalance
• Bit Error Rate
• Message Error Rate
The 3920B can also display graphically the modulation error. These
graphical displays are:
• Constellation
• Vector Error
• Phase Error
• Magnitude Error
AUTO-TEST II
Available as an option for the 3920B is the Auto-Test II operation.
Providing the ultimate in flexibility, this option gives you the ability
to control the operation of 3920B using the TCL scripting language.
You control the functions of the 3920B through the use of RCI commands, which are sent as part of the TCL program.
