Agilent 16801A Logic Analyzer Repair
« on: May 11, 2024, 06:46:12 am »
I have an Agilent 16801A logic analyser that was booting without issues, but now does not boot and gives one long BIOS beep and gets no further. Does anyone know the bios codes for these machines as I cant find anything in the service manual.
I have ordered replacement DDR ram modules as a starting point for fault finding

i would suggest pulling out motherboard from unit and connect it to std atx desktop psu and external vga monitor  and short the two power pin on motherboard.

if all good it should boot to bios

the internal psu of logic analyser wont work unless everything is okay

Did manage to get this sorted in the end, had to replace the motherboard which was a standard item off the shelf

good to know.

i believe your unit is a two slot model and the second should be a pattern generator.

Mine unit is failing few test on pattern generator
