I am working on an 8712ES vector analyzer and I upgraded the firmware without saving the correction constants first.
Well, this erased all the constants and now the (power) level flatness is not so (4 dB change).
The service manual says that a floppy disk was shipped with analyzer, that contained all the original correction constants. Unfortunately, I cannot locate this disk. (Analyzer was purchased new long ago.)
Is it possible that Agilent still has this file on record? The file takes the form of CC_DATX and is specific to each analyzer (model and serial number).
Otherwise, the analyzer works great and has plenty of output power.
Any help would be much appreciated,
