Can't send the command "measure" to device

[sonicbang]

i'm using a pci-gbib on a linux-system (driver v 0.82). now i have a little problem: i'cant send the measure command to devices without error on it. if i send *idn?, *rst ... the device will work properly. what am i doing wrong? are there example programs? does i need the polling?

thx

Hello,

The problem may be determined by the error. The following web page describes common GPIB errors, causes, and solutions.

Also, make sure that the command that you are using is recognized by your instrument. Since the instrument is responding to *idn? and *rst, the hardware and software are set up properly. I would focus on determining which commands the instrument understands and when you can use them (ie. board vs. device level). For more information on when to use GPIB commands go to the NI-488.2 Function Refernce Manual (see link below).
