I just purchased an 54845A scope and when I run the self calibration all passes except on all 4 channels the trigger fails. I used a 9" 50 ohm cable to attach AUX Out to each of the 4 channels when prompted, all 4 channels the Vertical passes but all 4 channels the trigger fails. When using the scope I have no problem triggering on waveforms. Should I send the scope in for calibration? Any idea how I can get the self calibration to pass? Thanks...

After running the self calibration when all 4 channels fails trigger, under details it states: Main Errors: Logic Trigger Duration, Logic Trigger Delay, Main Trigger Threshold Delay, Main Trigger Runt Delay, and Main Trig Time Qual Runt Delay. Does anyone know what the problem might be and how to fix? Thanks...

You'll need to send it in for repair, not calibration.

Good Luck,

I have seen these series of scopes do the same thing, pass all cal routines except for failing all trigger routines. I have fixed this problem on some units before and it has worked just about everytime. Sometimes this solution does not work and then that means a real problem is present. To fix my scopes I reload the firmware or upgrade to a newer one. If the scope originally had ver A.04.30 then download that version from agilents website and try to reinstall it on the problem scope. I bet it works fine after firmware reinstall or upgrade.
