Dave repairs a HP 35670A Dynamic Signal Analyser. Well, kinda…
Hi there Dave,
Could it be that there is a problem with the I2C memory, and if that device stores the cal data results in calibration failure?
And the cause of all those failed ADC tests could be because there is no cal data.
Well, it’s just a guess. Hope it helps.
Nice video, as always 😉
Possible, but I doubt it. I think there are likely more PSU issues on the other boards.
As the power supply went out and you tinkered around with it, you found that the primary side does not work.
I was thinking all the time, why the heck does he not check the Fuse ?
So I really hope you checked the Fuse ?
Maybe the Instrument is still 220V vintage and your Sockets get 250V out. That might be a reason for the fuse to blow. (or for the power Supply to die.)
