Dear Gedas,
There is a way round this you might find useful- reference line extension function; I used this on an 8753B to take out the delay in a long optical delay line.
Essentially, you sweep over a frequency range that the DUT is phase linear over.?
Then adjust reference line extension until you get flat phase.?
Then read off the extension in ns.?
Then calculate the phase shift from frequency and delay.
I have n’t checked whether the same function is available for E series analysers; it would be a pity, if not.
Regards,
Alwyn
