Radio Communication Test Set

The Radio Communications Test Set Marconi 2955B provide comprehensive test facilities for AM, FM and ØM mobile radio transceivers operating up to 1000 MHz. The 2955B is a combination of the following instruments:

• RF power meter.
• DC and AF voltmeter.
• RF counter.
• AF counter.
• RF generator.
• AF generators (two).
• Modulation meter.
• AF distortion, SIN AD or SIN meter .
• Sequential tones decoder and encoder.
• DTMF decoder and encoder.
• DCS decoder and encoder.
• POCSAG radio pager encoder.
• Sensitive receiver (Option 1 only).
• Digital oscilloscope.

These are automatically connected to the appropriate socket when an operating mode is selected. A large CRT display shows all the generated and measured information for each test and a direct indication of the control settings being used. The 2955B can be used to check a wide range of equipment including simplex and duplex radio telephones and mobiles using selective calling and cross-band repeaters.
