Does anyone have a PDF of the service manual for the 54754A TDR plugin?
I have a (new to me) 54754A P/I that fails calibration.  Does anyone have a PDF of the service manual?  AFAIK, there isn't a CLIP for this series, so I'm just trying to figure it out.   Many thanks.

Loading dual channel waveforms from USB on 33522A.
Hi, I have a dual channel waveform that I created on benchlink waveform builder. I can load that dual waveform to the generator through direct USB connection to the PC or Ethernet, and all is well. But if I save the waveform on a USB stick and try to load the waveform through the USB front panel, I get an error that "Dual channel waveforms are not

Calibration of a Differential TDR module
Using an 83480a digital communications analyzer, I have attempted to test and calibrate several TDR modules. (54754a, 54753a & 54752a) When they fail calibration, I have replaced the control board in the TDR module and matched the two dip switch setting and after recalibration, they pass (the serial number follows the control board) Then I

re: Layout vs schematic simulation results
Hi, I designed a LCL circuit for testing purposes using 2 micro strips and a chip cappacitor. I run the S parameter on it and i get the expected results but when i generate/update the layout and run the EM the results are totally off. I checked the FR-4 substrate and i changed the capacitor type , added solder pads ,frequency range etc.
