I'm trying to assemble a work-station that I can use to restore/re-cap old radios. I have some old signal generators that I would like to test as well as the oscillation of circuits in the old radios.
What kind of frequency counter do I need? There are several models on ebay for around $100, but the maximum input voltage is 30V. Is this going to be a problem?
Would an older model HP be a better choice? Such as an Agilent HP 5316A?
Also, none of the ones that I see for sale do not come with probes. Where do I get probes? Any help would be greatly appreciated.
