Where did you find the firmware ROMs?
Also, do you know if firmwares can be upgraded for all mainboard revisions?
According to the assembly level repair manual, there has been several ones.

go to KO4BB web site: http://www.ko4bb.com/getsimple/index.php?id=manuals and search for "53132A"

BTW: I have updated the component list inserting DigiKey codes and links

TheSteve:
There are also a couple threads posted on the forum here with firmware attached.

Hi everyone,

Thanks for your answers.
I've also checked other 53132A related topics, lots of discussions and information.
In particular, about how to switch to a less noisy fan or how to calibrate (there is even a calibration fixture in the work).
It would benefit us all if we can put all the related information on one webpage, KO4BB comes closest to that.

One more question, I've noticed that latest available firmware is "4613". That would be 2006 (HP serial number is 2 first digits + 1960).
Will that work with any hardware revision of the 53132? In particular, early ones? Mine has serial number 3546A...

Best regards,

Your serial number seems to be the early version with HP in stead of Agilent on the front panel.
Based on a service note 53131-04A, S/N below 3710Axxxxx seems does not have the mother board 53131-60004.
I think mother board will be the concern instead of firmware version.

I also got an US version HP 53131A with S/N start with 3736A.
It can be upgrade from FW rev3703 to rev3944 without any problem.
Although I haven't tested yet, but I don't think it will be a problem for running rev4613.
