Re: 11801 is reassembled, up and running :-)

11801 User manual p 42.

"The signal from the calibrator output us a 250 mV square wave with a rise time of approximately 20 ps and a period of approximately 10 microseconds."

After I did the Enhanced Accuracy cal process I got results similar to yours. I eventually got it to do something sensible after a bunch of semi-random button pushing. Pulse amplitude was not stable on the display among other weirdness. It is now behaving as one would expect.

Someone else has stated that the calibrator is the same as the pulse generator in the SD-24.

I am now getting the same results I got before I replaced the NVRAM.

Calibrator risetime? Isn't the cal output
specified at about 250ps? Both of my instrument measure it
about 300ps.
