What is a good Freq Counter?
Can anyone recomend a good frequency counter brand/model. I'm looking for something 100Mhz or less for counting pulsetrains on game boards. I don't really need totals, just pulses over time.

I picked up a HP Signature Voltmeter from eBay for a good price a year or so ago, has a nice counter built in...I have some spare parts, thanks to Al K. who sent me a dead one. John :-#)# At 04:54 PM 21/01/2002 -0500, Kev wrote:

Be careful now, although some voltmeters have frequency counting capability, most don't work well past 1 MHz. And they may be fussy about signal levels. Check the specs before buying. John Robertson wrote:

What model is yours & what are the differences between the various HP models? Thanks, Kev
