What was the effect of having 120 AC @ 400 hz as opposed to 60HZ.?? Had 400Hz hum instead of 60??

This could be a very long post but since I'm wine(ing) I'll keep it short otherwise I might have to think.

In my world we have to live in an environment from shipboard (aircraft carrier is one of the worst cases) to airborne (F-whatever fighter jet), missile or drone so the environment can be way baaad from an EMI perspective. Shielding wires/cable runs is one of the methods used to survive this harsh EMI environment - just need to design it into the overall design. EMI can affect the overall data quality - so any way that you can mitigate these issues helps in getting better data to evaluate the system under test.

Got it. I'll need to update my DC protect board. I haven't removed the wire wound resistors yet but it seems that that the thru-hole diameter on the PCB is on the smallish side for a five or ten watt resistor. Yeah - it's tough making something large fit a small hole. I like how you worded that though.
