If I fire up my E4406A and issue an SCPI control string to it, then capture a spectrum and request a GIF grab using PSAPLOT, it works fine the first time.? Subsequent use of the same command result in a read error 0x2.? I can't find any commands which will reset the thing.? If I power-cycle the 4406 and run the SCPI config string again (or set it up manually), the same thing happens, first read to GIF is fine, subsequent ones fail.? Using a Prologix USB GPIB interface v6.4.1 with driver v6.107.? It works fine with all my other GPIB instruments.? I have now isolated the 4406 so it is the only device on the GPIB. No change.
SATRACE and SSM also fail with the 4406, either locking up or reporting an 0x2 read error.
Any suggestions of what to look for, any diagnostics to try, or if the E4406A needs any special config settings in PROLOGIX.EXE?? The backlights have failed, so seeing what is on the display is challenging, and I certainly can't just take a snap of the screen.
