Can anyone recommend a decent frequency counter for lab use?
The cheapest Agilent (53131) is now about $2100. It has a fairly good, but not ovenized, timebase... looks like a TCXO. It is a "universal" counter, start/stop trigger levels and all that, so it's not too bad a deal. Seems a tad expensive, though. I'd like something good to at least 1 PPM, so I can use it to calibrate our waveform generators.
We'll probably buy new here, so it comes cal'd and known good.
