content: I may have to disassemble mine because the cal ref level is off, and there is no menu option for adjusting it. If you have Gigatronics 8652A, do you know: What is its controller ? Is the rom outside the controller and is readable?

content: There is nothing to adjust there. Gigatronics calibrator ref level is set up by setting a CALFAC number. The older meters like 8541\8542 had access to this through menu:MENU -> SERVICE MENU ->CALIBRATOR -> EEPROM -> SNumb (unit serial number) -> CALFAC changebut their calibrators were fixed 50MHz.The newer 8651/8651 series apart from 50MHz also have a range of frequencies from 800MHz to 1GHz, option 12. So they may probably have two or more cal factors.What I need is know is how to access, change and save the CALFAC-s on the newer models. There must be an external programming protocol or hidden service menu or both.The cal-labs calibrating these meters certainly know how to access the CALFAC-s.

content: Yes, now I still looking for schematics on all gigatronics power meters and maybe firmware files, for example to make 8542C from 8542B as I was do with anritsu ML2407 and ML2437

content: @ picburner. Thanks a lot for the files.@ romal 76. I have 8652A and I was also curious if it is possible to convert 8652A into 8652B. I only have schematics of 8540C, if you have something else, can you share ?

content: Athttps://web.archive.org/web/20071018084015/http://gigatronics.com/support/index.php?p=5I have found that giga-tronics was distributing the utility to upgrade/reflash the firmware. Unfortunately, the binary is not archived. Someone has the file? I am desperately searching it since my 8651A is dead and everything seems ok. Thank you

Probably it is stupid question, but is anybody tried to repair probe with BAT24-02LS?https://www.infineon.com/dgdl/Infineon-BAT24-02LS-DS-v02_00-EN.pdf?fileId=5546d46265f064ff016638964eed4e95Of course, it will require to full recalibration but looks like it is possible as for me.

content: Is it possible to test measurement unit without sensor? I got one as broken. But I still haven't any sensors. The unit is booting properly. And allow to change calibrator frequency up to 1GHz while missing Option 12 lable on backside.

content: The old Giga-tronics website had available "V1.58.bic" firmware file for 8650A but that was not archived by Archive.org. Anyone has that firmware version? I am not sure if Spanawave released something newer since they don't even have an email address for contact. I see only phone numbers there...
