Agilent E8357A

No problem, I'm in no rush. When you get to the point where you are going to align yours, it would be very interesting to use the CW mode, with the output set to 0dBm and measure a few points manually.
I would expect the meter to read 0dBm but who knows, maybe it's -6ish.
I was concerned with the BR2335 being so odd, if I bought one how long had it been on the shelf. A lot of my devices use the CR2032 which is a bit smaller OD and thinner. I doubt it would pop out but you may only get a few years of service life.
caesarv:
Interesting. I did not even know the difference between a CR and a BR battery until just now. I have always replaced them with a CR battery because they were much more common and have never had a problem. Now that I have looked it up, I agree that a BR would be slightly better for the RTC, but I doubt it makes much difference. Both should last 5-12 years...longer if it is kept plugged in. I always used the common CR2032 battery Just pry the battery out....I have never damaged the board by prying it out...but I was only working on the 500 MHz board. I do not remember if the 266 MHz board had a similar battery.
With regard to what I said earlier about the mxcal files being about the same: I probably should have added the caveat that this may apply ONLY IF you have the same options. The one I provided was for an E8358A with 3 jumpers on each side of the front panel. If you only have 2 jumpers on each side, then my guess is that you should use the mxcal files from a similarly equipped instrument. I can provide a set of those files also.
joeqsmith:
I believe Forzaman's is also the 3 jumper system. Mine is the two jumper, no frills. If you don't mind, please post the files you have for the 2-jumper. Maybe this will explain the offset.
Also, mine is the low end computer and uses the same battery.

Yes, I have option 015. Ok, I'll try to pry out the battery. The 266 and 500 MHz CPUs use the larger 2335 size coin battery (BR type) whereas the 1.1GHz uses the 2032 smaller size.
Forzaman:
Caesar, are you familiar at all with the configurable test sets available for the E835xA PNAs that allow 4-port measurements?
There are quite a few N4416A test sets available for the E8357A, but none come with the N4425A Balanced Measurement Software required to control it. I was wondering if the software requires a license, and if so, is it node locked to the PC. If it is node locked to the PC, then I will give up my search, but if it is somehow locked to the test set, then I will continue my quest to get one with the software. Thanks!
