2-21. Frequency Counter. The frequency counter measures inputs in a range from 10 Hz to 35 MHz. Its 5
digit auto-ranging output is displayed on the CRT and allows precise measurement and setting of offset
oscillators, 35 kHz and 455 kHz pager IF's, PL frequencies and other external input signals. This function will
also operate simultaneously with the generate or monitor receiver modes of operation. Frequency
measurement of transmitted carriers and other signals higher than 35 MHz is easily accomplished with the
frequency error readout in the monitor modes.
2-22. AC/DC Voltmeter. Switching to the DVM mode provides a digital-analog voltage presentation on the
CRT, along with the corresponding dBm value. The auto-ranging display provides full scale deflections of 1,
10, 100 and 300 Volts. AC or DC measurement is selected on the CRT. The meter's wide dynamic range and
three digit display are ideal for setting power supply voltages, checking bias levels, and setting audio levels.
Like the Frequency Counter, the DVM will operate simultaneously with generate or monitor operation.
2-23. Power Supply. The Communications System Analyzer may be powered by a variety of sources:
• AC at 110 or 220 Volts, 50/60 Hz
• DC from an external 12 Volt source such as a service vehicle
• DC from an optional battery pack. Servicing can thus be accomplished wherever the equipment under
test is located
