How do you do HF compensation adjustment?
Some high quality (read expensive) probes have HF compensation adjustments internally. You have to be able to take them apart to do the job and the specs/process have to be published. Better Tektronix probes fall into this category.
Well no.
Based on what I said in reply #5:
https://www.eevblog.com/forum/testgear/probe-into-probes-whats-up/All the 500 MHz probes I have ever seen have external HF trimmers and normally 2, both sealed with a plastic cap easily removed with a blade, not too sharp that might slice the plastic cap in half.
Typically with these 500 MHz probes a 1 MHz rising edge of 1ns or better is specified and tweaking of dual trimmers....yes there are 2 in order to get the best step response and with NO overshoot !
Here is where I run into trouble, why on earth not use the Bodnar pulser as a HF edge for adjusting HF step response, it's certainly faster that 1ns and at 10 MHz instead of a specified 1 MHz, why could that matter one damn ?
How might we realistically accomplish these adjustments noting that when the Bodnar pulser is connected directly to a scope there
certainly is overshoot....something we would normally trim out when compensating a probe.
In my view and please correct me if you know otherwise, we should attempt to
replicate the Bodnar step response when connected directly to a scope when making HF probe adjustments which flies directly in the face of HF
trimming out of all overshoot. Interesting dilemma IMO.
We can see some of Bill's probes are in need of HF step response adjustment and based on what I learnt in Bill's probe-into-probes-whats-up thread I would pick probe 5 or 8 as his most expensive and 9 the cheapest......but I've been known to be wrong before !
