Welcome to Azur Electronics. This Counter has options fitted: Other options were also available: The serial number is much later than the downloaded HP Manual so several assemblies are different. Front view with low and high ho inputs.

HP / Agilent A 10 Hz to 18ghz Microwave Frequency Counter OPT & | eBay

Signals in the frequency range of 10Hz up to MHz are measured by the direct count method. Signals in the frequency range of MHz to 24GHz are down-converted to an IF by a harmonic hetrodyne conversion technique. Signals are normally measured using a fully Automatic mode.


Alternatively signals can be measured in a Manual mode by entering the centre frequency within 50MHz. This is useful where there are several signals of different frequencies.

Frequency values to 1Hz resolution can be added to or subtracted from the measured frequency for IF Offset applications. All frequencies are displayed with up to 11 digits of selectable resolution from 1Hz to 1MHz on a red led display. The Counter has good FM and AM tolerance and automatic amplitude discrimination against other signals.

I use this as my ‘reference’ counter and also for high frequency measurements. Specifications Input 1 High Frequency Range: After this and a good clean up, the performance test 5342 carried out.

This “locks” all the counters together to provide more accurate measurements. October Acquired a second HP A as part of a ‘job lot’ of equipment.

January Started testing this second A but it had some faults and needed a good clean. Frequency and Amplitude measurement. With Amplitude Measurement mode selected, the frequency is displayed on the left and the amplitude in dBm on the right.


This is useful for a quick check of amplitude as well as frequency. November Acquired a third HP H as part of a ‘job lot’ of equipment.

This one has no options fitted. December Started testing this third A but it occasionally blows the mains fuse and doesn’t count on the MHz to 18GHz range. December Now repaired, decided to keep this A.
