I bought a 5370A on *bay last week , and the unit is supposed to arrive tomorrow.
I have never used such a beast , and as the seller wrote it is fully working , and passes self test. I was wondering if anyone could give some hints to test that it's working ok. I mean the input stages , known defects etc. ? I have a Tbolt ,a PM6680 Counter , a cheap Rigol DG1022 Func Gen, a working Linux-Gpib installation , and a Prologic GPIB-Ethernet adapter. And for clock sources: A Morion MV89,some 10Mhz *bay #310380778466 5v square out i think, some Pletronics 26Mhz OCXO's, a X72 Rubi, some FEI Rubi's and some Jupiter GPS boards to test with. But what do i do for a start ? Besides opening it up and vaccum clean it ,set it for 240V, and check if there's a OCXO in there ? Also what are the input voltage limits ? I'd rather not start by killing the input stages my self. I think i read around 1volt for the 5370A , and 3.3v for a 5370B ? But i also think Bruce wrote that (maybe only the B) would accept 5v , as the clamping diodes would then be active. Somewhere i also read that a 5v signal via a 270R resistor would be ok on the 5370A Thank you for any hints/tips,warnings or help.
