Finding and Querying Instruments

Finding and Querying Instruments

This section shows how to find and query GPIB and/or RS-232 instruments
connected to your E5810 by using the

Find and Control Instruments

Connected to your E5810

page. This page is password-protected since you

can inadvertently interfere with running VISA/SICL applications if you query
an instrument at an inappropriate time.

This page allows you to quickly communicate with your GPIB and RS-232
instruments and can help you determine if the instrument side of the E5810
is working properly. You can also use this page to set up and take
measurements remotely by sending instrument commands.

Click Device Clear, *IDN?,

Read STB, or SYST:ERR?
