2944 Communications Service Monitor
• Automatically tunes to transmit signal
• Proven performance backed by IFR’s long
history of RF test excellence
• 0.5 ppm TCXO standard
• Duplex RF output levels down to
-141 dBm
• SSB phase noise better than -95 dBc/Hz
• Dual audio generators from 10 Hz to
25 kHz
• Narrow and broad band power meters
• Full function audio analysis tools
Audio bar charts
Audio voltmeters
Audio S/N meters
Audio distortion meters
Audio frequency meters
• Rugged lightweight package

tracking generator and offset tracking
• Accurate power measurements to 150 W
• 5 W protection on all RF ports standard
The 2944 Communications Service Monitor is
the lightest, most rugged service monitor available with a full performance spectrum analyzer
as standard. For field work the 2944 provides
an excellent combination of instruments for all
types of maintenance work. In the workshop, it
provides all of the performance you would
expect for exacting measurements.
Full Featured, High Accuracy, Low Cost
Designed for the wireless communications professional, the 2944,
shown with optional bail arm (OPT30), includes high powered accuracy and features at a very affordable cost. RF professionals involved
in day-to-day AM/FM measurements can use the 2944 to perform all
of their transmitter and mobile unit measurements without having
to pay for “extras” that add cost to other service monitors.
Field Operation
At under 12 kg (25 lbs.), the 2944 is the lightest RF Communications
Service Monitor on the market. Using the proven Aeroflex look and
feel of the 2945A series, the 2944 is ideal for carrying. The side handle ensures that the instrument is clear of stairs when ascending
buildings and the depth is suitable for the 2944 to be operated comfortably when it is placed on the floor.
With the optional bail arm, the 2944 allows a stowage cover to be fitted over the front panel for storage of adapters and further protection to the instrument’s front panel. Full operation is possible from
the “ever-ready” case so that your instrument is protected from transit damage.
Battery - Carry a Spare
The battery fits neatly into the “ever-ready” case and is easily
replaced with a spare when discharged. There is no memory effect
associated with the battery, even when partially discharged.
Fast Warm Up - Fast Results
The standard TCXO allows results to be made reliably within a
minute of switch on. Where even better stability is required, an
optional OCXO is available (OPT3). Stored settings may be recalled
from internal memory allowing fast and straightforward setup.

Fast Full Performance Spectrum Analyzer - Provided as
Standard
The spectrum analyzer provides spans from 100 Hz per division to
full span and has a fully adjustable reference level. Speed is comparable to analog analyzers, allowing real time adjustments over the displayed dynamic range. With the optional tracking generator, duplexers and filters can be aligned quickly and easily. An offset facility provides testing of equipment with frequency translation. Channel stepping can be performed by defining an increment and then using the
FREQ ×Ø keys. This is particularly useful when testing multi-channel systems.
High performance spectrum analyzer provided as a standard
feature
From 2 µV to 150 W
The 2944 will measure the power of low level signals such as those
encountered when monitoring off-air signals or those found when
probing a circuit. 150 W measurement is provided without the need
for external attenuators, so high power base stations can be measured
directly. Measurement accuracy of better than 10% is guaranteed all
the way down to 5 mW on the N-Type connector, allowing radios to be
qualified at low power levels.
Accurate RF Signals
The signal generator provides coverage from 400 kHz to 1.05 GHz
with +5 dBm output (+7 dBm overrange) and fast switching speed.
Level accuracy is ±2 dB at all levels above -127 dBm.
Duplex - Provided as Standard
Full duplex operation is provided by the 2944 allowing testing of
duplex radios as well as simultaneous testing of repeater transmit and
receive paths. There are no restrictions to the duplex offset.
2944 provides full duplex capability
Remote Control - RS-232 or GPIB
Remote control is provided with an RS-232 interface as standard. An
IEEE-488.2 interface (OPT5) can be fitted where other instruments
are required to operate in a system with the 2944.
Printing Made Easy
With the parallel printer port interface (OPT4), screen dumps, automatic test results or previously stored results may be sent to any parallel printer. These facilities are available as standard using the serial RS-232 interface. A screen capture facility is available so any screen
displayed can be saved direct to a PC, via the serial port, as a bitmap
file.
Audio Analysis
Full featured audio analysis tools include; audio bar charts, audio voltmeter, audio S/N meter, audio distortion meter and audio frequency
meter. A comprehensive range of filters is provided as standard,
including band pass, low pass and high pass. The direct measurement of CTCSS is possible with the 300 Hz LP filter, even with
speech present. Two full range audio generators are provided as standard for internal modulation or audio sources.
Comprehensive Oscilloscope
Analysis of audio signals, whether from the demodulated signal or the
audio input direct, can be viewed for further inspection. The oscilloscope can either be combined with the measurement screen in the
Tx, Rx or AF test modes or ‘zoomed’ to a full screen display.
Different levels of persistence can be selected to allow short or long
term effects to be captured.
Tones Generation and Decoding
The tones menus now include full remote control so that radio workshops can further automate their tasks. These and other improvements are in response to user feedback and allow better control of the
tones from the top level screens.
