Re: Limits of the Port Extension on the Cal screen for calibrating at end of cable
Karin, As I understand your question, you are concerned that the calibration data for a long cable requires larger numerical values due to the many 360 degree repeats of the phase. The analyzer

Re: checking line module setting for 110V / 220V
Many thanks for your great feedback. It gave me enough courage to pull the little card out. I found I had a pair of pincers with a hook on the tip. No idea what it was originally for, but worked

Re: HP8640B no rf out
The 8557/58/59 used the same kind of disks you could possibly find a parts mule on ebay though there is no guarantee that its not going to suffer from the same disease as this was a common problem.

You can try contacting Sphere Research in Vancouver BC, Canada. They have a lot of HP parts. Those wipers are part of the discs that are in the switch assy and no part number exists for the wipers as

Re: Info Need on a RF FET for a Agilent E4438C signal generator
Its a common issue that you have a lot of excess gain at lower frequencies and then roll off at higher frequencies normally you can combat this by using resistive feedback between drain and gate , it

Re: Info Need on a RF FET for a Agilent E4438C signal generator
Hello Lothar I do not need 27dBm output. As it is not the final Fet. but I think the gain of the SHF-0189 is too little. It has around 20dB at low freq but only 10 to 12dB at 4Ghz. so I might need

Re: Limits of the Port Extension on the Cal screen for calibrating at end of cable
As far as I am aware, the port extension feature only adds pure phase. You enter a delay parameter, or a physical length + velocity factor. I don't recall ever seeing any option to dial in any other

Re: Limits of the Port Extension on the Cal screen for calibrating at end of cable
I don't know about the 8753 in particular, but for the 8510, for example, the calibration correction factors are floating point numbers that are the coefficients for the third-order polynomial that

I realized a couple of hours after sending the initial post, that I was incorrect with associating Calibration with the Port Extensions. Here is, I hope a better explanation of what I am trying to do.
