Has anyone ever seen the following error message from an Agilent 33522A?
"Application Garfield.exe encountered a serious error and must shut down."
I have received this error message three times, and it:
1. Locks the GPIB bus (can't talk to it from Matlab, using Matlab instrument control toolbox, NI GPIB-USB bridge, and NI 488.2 software)
2. Locks the CH1 offset at the current value (can't change it from the front panel or remotely).
3. Pops up an error box on the front panel of the instrument. The only way to clear it is to power cycle the unit.
As far as I can tell, the error occurs after long periods of remotely changing the waveform offset voltage. For completeness sake, I'm using the unit in ARB mode, step filter off, sample rate 1kSa/s, burst mode, N-cycle, infinite number of cycles, trigger on CH1, trigger sync mode carrier. The connection is from a PC USB port to the GPIB port on the back of the 33522A unit using a National Instruments GPIB-USB+ dongle.
Can this be fixed, or should I return the unit for warranty service? I've been using it for about four months now, and seen this error three times. I can't reproduce it, but it hangs my program and I have to abort the experiment and restart. Very frustrating. Google has never heard of "Garfield.exe" for Agilent equipment, and the forum search doesn't turn up anything either.
I am using Agilent 33521A and the firmware as stated under the About page is 1.14-1.19-1.01-50-00. When I run my vb.net application with arb wave forms, I am getting the "Garfield.exe" error and unit must be restarted. Should the firmware I am currently on have corrected this problem?
