By any chance, has anyone here done any GPIB programming of the HP 3456A DMM? I am having great trouble getting it to output SRQ at the end of a reading; it appears as though it simply doesn't recognize the "SM" command that the manual says should be used to set the SRQ mask.
Setting the mask with, e.g., "SM004" which according to the manual should cause SRQ to be asserted at the completion of a reading, results in the "004" being briefly displayed on the LED during setup, but no sign of SRQ actually being asserted. I've tried numerous values of the octal code representing the status byte, but all act the same. I realize it's a long shot, but wonder if anyone here has wrestled with this?
