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 n ot 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.

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.
