Manual Datasheet Specifications
The HP 5342A Microwave Counters provide automatic frequency measurement to 18 GHz in highly portable package. The operating range of the HP 5342A can be extended to 24 GHz with Option 005.
Amplitude Measurements (Option 002)
Option 002 adds the ability to measure and display the power level of the input in dBm. The 11-digit LED display presents amplitude measurement to 0.1 dBm resolution. Also, the same option extends the instrument's dynamic range to enable frequency measurements to + 22 dBm.
FM Tolerance
Measuring a carrier frequency while it is being frequency modulated has broad appeal in the communication industry and elsewhere. The HP 5342A  can tolerate peak-to-peak FM deviation to 50 MHz.
Digital-To-Analog Converter (Option 004)
Option 004 lets you convert any three consecutive displayed digits (frequency or amplitude) into an analog voltage output on the rear panel. This makes the monitoring of microwave-oscillator-frequency drift easy to make with only a stripchart recorder.
Scaling and Offset Functions
The versatility of the microprocessor-controlled keyboard allows you to perform math functions by means of a few key strokes. Frequency values to 1 Hz resolution can be added to or subtracted from the measured frequency for IF offset application.
