For a beginner, I would support the suggestion provided by several others above:
A resistive ladder switched with low side Mosfets would be both the easiest to design and most likely to be completed successfully.
The YouTube aviation channels which show cockpit videos, and there are many, appear to use GoPro or similar cameras.
I am sure that they require permission and waivers from both the airline and pilot’s union.
EEPOTS, last time I used them more than 20 years ago, did have memory, but if I recall properly there was a sequence that had to be applied to store the last wiper position.
“Electro Mechanical memories” were used on some earlier presettable FM tuners.
Essentially hidden multiturn pots which you could use to set the varactor’s tuning voltage for a particular radio station.
Of course the tuners had AFC circuits to compensate for the inevitable drift.
Even with...
130 kV is X-Ray tube territory.
If this is indeed the case......
I agree that a dummy load should be used instead of a tube for troubleshooting. Operating an X-Ray tube outside its maximum limits is very dangerous.
Having used DC contactors and solid state switches extensively in industrial environments, I can tell you that the reason that DC contactors are so expensive, is that those must be capable of interrupting fault currents.
Unlike AC, with DC one doesn’t have the benefit of a zero crossing every...
Dana;
You worked at National during its glory days.
I also have a pair of Tom’s books. Bob Pease’s hilarious introduction to the OpAmp book is priceless.
Probes. Klaus has already mentioned HV and current probes.
I only would add a differential probe.
And make sure the current probe is hall-effect based. Cheaper transformer based probes have low frequency limitations. And certainly can’t display DC.
First of all, thanks for posting a schematic without being prompted.
There are several pitfalls on your circuit, I am going to start with the first one and allow someone else to point the others.
With a zero current input, the output of the AC712 sits at 2.5 volts. As the current increases...
