I have a broken Agilent U8903A Audio Analyzer. The output sections seem to work fine, but both the input sections show an amplitude value that seems off by some large scale factor when doing measurements. Also, the device throws an error when doing a firmware update, I suspect when it tries to flash the DSP for the output section. This leads me to think that maybe some flash or EEPROM chip containing the calibration values is bad.
Anyone encountered this issue before?
