Finding and Querying Instruments
Querying
Instruments Using
the Instrument
Command Line
For supported instruments, you can also query an instrument by first
highlighting the instrument in the Instruments Connected column, typing in a
SCPI command (such as meas:volt:dc?) on the
Instrument Command
line, and then clicking
Send and Receive, or Query.
To send a command to the instrument without waiting for a response, click
the
Send button. Sending a string to the instrument does not return a result.
To receive a string from the instrument, click the
Receive button. To both
send the string and receive a response from the instrument, click the
Query
button.
Example: Using the
Instruments Page
This figure shows an example history display after taking these steps:
1 Selecting the instrument at SICL address gpib0,22
2 Clicking the
*IDN? and Read STB buttons
3 Typing meas:volt:dc? on the
Instrument Command Line
4 Clicking the
Query button
NOTE
The History display buffers up to 200 lines of information. At 200 lines,
the last lines are overwritten with new information. At this point, you may
want to press the
Clear History button.
