Yes, but in the process of investigating the part, you destroy it.
What did the network analyzer say about this particular resistor?
What's the impedance and phase angle between 10MHz and 100MHz?
Why on earth would I need to know that?? The frequency of operation here
as you well know is only 20kHz.
You didn't use it previously on the caps and transformers.....?
Sorry, was there a cap I needed to know the SRF of? As for the
transformer, what would the VNA have told me that the other metrology
didn't? It was testing under the high working voltage levels I'd have
liked at the time to check for breakdown; no VNA I know of will do that.
