National Instruments NI-488.2 Benutzerhandbuch

To view information about your GPIB instruments, complete the 
following steps:

1.

Start Measurement & Automation Explorer as described in the 

 section.

2.

Expand the Devices and Interfaces directory by clicking the + next 
to the folder.

3.

Select your GPIB interface. 

Measurement & Automation Explorer displays the connected 
instruments in the right window pane.

4.

If you have not already done so, scan for connected instruments. 
Right-click on your GPIB interface and select Scan for Instruments 
from the drop-down menu that appears. Refer to the 

 section earlier in this chapter for more information.

5.

Double-click on the instrument displayed in the right window pane.

Measurement & Automation Explorer lists all the attributes for 
the instrument, such as the primary address, the secondary address 
(if applicable), the instrument’s response to the identification query 
(

*IDN?

), and the GPIB interface number to which the device is 

connected.

For older NI-488.2 applications, you might need to modify one of the 
device templates to find a given GPIB instrument by name, for example, 

ibfind("fluke45")

. Older applications still use 

ibfind

 instead of the 

preferred 

ibdev

 to obtain a device handle. In new applications, avoid using 

ibfind

 to obtain device handles and use 

ibdev

 instead. You can use 

ibdev

 to dynamically configure your GPIB device handle. 

ibdev

 also 

eliminates unneccessary device name requirements.

If you must modify a device template, run the GPIB Configuration utility.

1.

Start Measurement & Automation Explorer as described in the
