Rick,
We had received a similar error to the one you describe with the PNA and
E-Cal. I believe the error I received was E-Cal not detected. The suggestion
Joel had in his earlier e-mail is the solution we took. It was related to a
low power calibration and the loss through our RF fixturing. The E-Cal was
able to auto-detect which test port was connected to the E-Cal ports. I
turned auto port orientation off and set the mapping to how our software was
set to connect to the E-Cal. The error went away and we haven't had a
problem since.
Thanks,

Subject: [vrf] vrf E-Cal error on the 8753ES
Hello,
I've come up with an issue having to do with the E-Cal & the 8753ES. I'm
getting the following error even when the E-Cal module IS connected during a
calibration.......
ECal MODULE NOT IN RF PATH
It then does not finish the calibration (but also will not lock up the
Analyzer).
This appears to be happening only when sending the automated commands to
perform an E-Cal as when I try to calibrate manually through the Analyzer's
front panel it never happens. I have example code attached. If anyone can
tell me what I'm doing wrong or maybe it's a bug in the 8753 firmware?
By the way I appreciate Agilent's direction in allowing E-Cal to be
implimented on the 8753, it is a real time saver and I'm getting positive
feed-back from the Tech's who are now using it.
Thank You,

I ran this on my 8722ES using an RF ECAL, 50MHz-3GHz. Worked fine.
I have seen some problems if there is too much loss from the 8753ES test port to the ECAL connection.
The failure is usually in what we call "orientation". I can't say why it should be different remotely
than from the front panel. I haven't seen this reported before as a defect. Which ECAL and what firmware
rev are you on? (My 8722 was rev 7.70).
One -probably not related- thing to try is to turn cal off before starting an Ecal. I've seen it reported
that ECAL reports "no-module in path" intermittantly if ECAL is done with CAL on, but I can't verify that
it's a problem with my 8722. (Tried both ways, every thing still works fine). Other things to try is to
put the '53 in hold mode first (maybe some weird timing?). Don't know.
Best Regards, Joel
