 Post subject: Frequency Counters – Which one of these would you keep?

I recently picked up several frequency counters. They are all in excellent working condition but none of them came with any manuals or paperwork. They are as follows:

1. B&K 1801
2. Goldstar FC-7051 – Rebadged as “Scope.”
3. Heathkit IM-2410
4. Atten F1000-C – New from China
5. RSR FG-32 – Multi-Function Unit

Is any one single unit the “best?” Are any of the units duds that should be avoided?
Or are all the units pretty much the same? Which one would you keep?

Any information would be greatly appreciated! :D

Too many variables.

The answer depends on YOUR needs... and what you find easiest to use for all your typical applications... then calculate things like resolution, accuracy, sensitivity, etc etc.

The other choice is:
Keep the prettiest one.

Then ...I'll take all the other ugly ones off your hands for a flat $50 shipping cost for the lot in one box.

I would get rid of the B&K and the Heathkit. The FG 32 is a function generator wit a sweep which you may find useful. The GoldStar goes up to 550Mhz and the F-1000 goes up to 100Mhz, These are both newer and you may want to keep both of them. You can never have too much test equipment :lol:

I suggest doing some tests with various signals to determine upper frequency limit and more importantly, sensitivity. A counter that need half a volt to even trigger isn't worth very much.

I'd sell them all and buy a Hewlett Packard "frequency" or "Universal" counter. Something among the 5314 - 5316 or 5384/5385, or a 5345 if you want a full size 500 MHz universal counter.

With a little patience these "top shelf" counters can be had for not much more than any of the ones you mention. It would be quite possible you could even make some money when all is said and done.

They're all about the same in terms of stability. I would keep the Heathkit IM-2410 myself if it is working. It has better sensitivity (10 mV up to 30 MHz) than most other counters, and it will trigger reliably on waveforms that would drive the other counters--including HP models--to despair.

+1 Mike has the right answer.

Agreed. Also, if you do any low frequency work, the HP reciprocal counters work way better. Nobody seems to want/use dedicated frequency counters much anymore, so they can often be had cheap.

+1 - I used a Heathkit for years, adding an $11 divide-by-ten prescaler for 400MHz use, and later got a great deal on an HP 5351B, but the Heathkit STILL would meet my needs.

Peter's philosophy applies to so many things - from cell phones to tools to vehicles to homes......
