The AUX output on the MSO9000 series oscilloscopes is located on the back-side of the unit which is sometimes difficult to access when performing skew calibration.
My question is this:
Q1) How critical is it that the E2655 deskew fixture get applied directly at the AUX BNC output?
Q2) Can a short (0.5-meter or less) BNC cable be applied between the AUX output and the E2655 deskew fixture when calibrating high-speed probes?

If you want to do this, no problem, just recognize that if you do a skew cal on one channel with the cable, and a skew cal on another channel with out the cable, the 2 channels won't line up.
BTW, I never do an 'official' skew calibration. I'm mostly working on serial buses, and the location of the trigger doesn't matter. All measurements are made between channels. I deskew the channels relative to each other by putting them both on the same signal, and adjusting the skew in the Channel dialog.
