Dear group, I consider buying a used lab frequency counter / timer --preferably HP/Agilent-- covering from few mHz to perhaps 400 MHz. I'm worried that models handling high frequencies seem to be limited to under 100 mV input signal max. I don't want to destroy an input channel each other day when calibrating/repairing some instrument. Also are there instruments with high impedance input? 50 Ohm is not quite right for investigation in the guts of most designs.
Is it possible to find a not-too-old model under $800? I would like to find something in France or UK or Europe, but it seems hopeless in this budget. I would favor a repairable model (with available service docs & schematics). Your expert advises are more than welcome! -- <mailto:[EMAIL PROTECTED]>[EMAIL PROTECTED] _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
