 2955A / B is a radio tester, which includes testing range to 1000 MHz for mobile-free 
 Radio transceiver transmitter all the required measuring equipment, is designed for bench or mobile applications, the tight 
 Minato supporting device, it can viewed as a combination of the following 14 instruments: 
 Radio frequency, audio frequency counter, RF signal generator, RF power meter, audio and DC 
 Pressure gauge, modulation table, the table distortion, SNR (S / N) or satisfied (SINAD) meter, digital storage oscilloscope, 
 Tone sequence decoding and encoding, dual-tone multi-frequency (DTMF) decoding and encoding, digital code squelch (DCS) decoding and encoding. 
 Button to select measurement for each instrument provides all the necessary interconnect, eliminating the use of sub- 
 From the various equipment needed when the number of interconnection. Feature selection and data entry in the color code on the disc, from the 
 Logically arranged from left to right order of operations encoder. Using cathode ray tube oscilloscope, greatly enhanced 
 Instruments, to provide data input sequence of operations guide tips and also shows the instrument settings and measurement 
 The amount of results, repeated scans through the oscilloscope, and maintain a single, and five auto-range bar graph display 
 Analog measurements.
