I'm using a ProLogix GPIB-Ethernet adapter to interface to a 437B power meter. I can communicate with the unit fine, but I'm getting continuous streaming of power readings from the device, which is making it hard to read back responses to specific commands that I send. I have a .pdf manual for the 437B, but all the pages are images, so I can't search for text. I found a reference to "free running" vs "standby" modes, and I see notes saying that it is normally in free-running mode on HPIB unless specifically switched to standby mode. However, I don't see any command to specify this mode, and as I noted, I can't actually search the document. Can anyone tell me what command would set standby mode on the HPIB port? I would be very grateful!!
