I am very interested to follow this thread since I might well need to
recalibrate a 2465B and I am not keen on removing the NVRAM without some
better de-soldering tools. I have no problem in providing the timing
references from some home made synthesised generators and low frequency
amplitude calibration from a PG506 but I don't have anything beyond a SG503
for constant amplitude at high frequency.
Hey Roger,

From what I gather (from Chuck's post
https://groups.io/g/TekScopes/message/169366) is that the SG504 or similar
is used for bandwidth performance validation. It sounds like when you play
with the transient response calibration, you'll need to compromise the
response against bandwidth.
I don't have experience with this myself, as when I calibrated my 2467 I
didn't touch the transient response calibration as I didn't have a pulse
generator fast enough at the time.

I have a 2465 I need to re-cap and calibrate one of those days, at which
point I plan to mess with this and make note of the signals required by the
calibration process.
