IFR / Marconi 2947 Communications Test Set 1 Ghz SERVICE MONITOR w/Accessories NEAR MINT
INCLUDES FRESH CALIBRATION A $400.00 VALUE - SEE BELOW FOR SPECS ON OUR IN-HOUSE CAL LAB.
Comprehensive IFR Systems Marconi (Aeroflex) 2947 1GHz Communications Test Set includes a High Stability OCXO, Analog card, Memory Card, GPIB, SSB, 600 Ohm Audio Interface & Low Noise Signal Generator with a full span spectrum analyzer and an offset tracking generator in a militarized rugged lightweight package. Tested and conforms to MIL-T-28800 Type II, Class 3, capable of 150 Watt RF power measurements, also 5W protection on all RF ports. Two variable audio generators provide an extended range of testing possibilities. More features are as follows:
The 2947 communications service monitor was built to meet the requirements of the US Navy and Federal Aviation Administration. It is the lightest, most rugged service monitor available with a full performance spectrum analyzer. The 2947 provides an excellent combination of instruments for all types of maintenance work while providing exacting measurements for use in repair and calibration laboratories.
Field Operation At under 26 lbs (12 kg) the 2947 TestMate lightens the load to remote sites.
The form factor of the 2947 combined with the bail arm make it easy to carry and positioning for optimal usage. A front cover over the front panel for storage of adapters and further protection to the instrument’s front panel.
Fast Full Performance Spectrum Analyzer. The spectrum analyzer provides spans from 100 Hz per division to full span and also has a fully adjustable reference level. Speed is comparable with analog analyzers, allowing real time adjustments over a full 50 dB dynamic range. With the tracking generator provided as standard,
duplexers and filters can be aligned quickly and easily.
This feature puts the 2947 TestMate above all of its peers with the ability to examine signals on the screen and demodulate them simultaneously. Intermittent interference can be isolated quickly and the signals then easily identified.
From 2 μV to 150 Watts The 2947 will measure the power of low level signals such as those off-air or those found when probing a circuit. 150 Watts measurement is provided without the need for external attenuators.
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 Full duplex operation is provided by the 2947. This allows testing of duplex radios as well as simultaneous testing of repeater transmit and receive paths. There are no restrictions to the duplex offset.
Cellular and Trunking - built in AMPS and TACS analog cellular standards testing.
The SSB demodulator allows signals to be demodulated either via the internal loudspeaker or via the accessory socket. (upper and lower sideband in the 400 kHz to 1 GHz range).
The 2947 simulates the signaling protocol that the radio would see from the real network. This allows calls to be set up and handled enabling receiver and transmitter parametric measure-ments to be made.
Remote Control - RS-232 or GPIB
Remote control is provided with an RS-232 interface or by IEEE488.2
Automatic testing without an external controller is possible. Custom tests may be written and run by the operator.
Users may program the instrument to suit their own specific needs by configuring any of the 4 built-in programs or by using the MIBASIC interpreter.
Comprehensive filters are provided 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 comprehensive audio generators are provided for internal modulation or audio sources for transmitter stimulus. External DC coupled FM is provided.
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.
The ability to capture transients on the rising or falling edge of a waveform provides a valuable tool for fault finding radios and radio systems.
An automatic harmonic analysis function is included to complement the fast spectrum
The tones menus now include full remote control so that radio workshops can further automate their tasks.
