:SOURce? Query frequency input source
Short-form format: :freq:sour?
Response message: CURR or VOLT
This command is used to select the input source for the signal to be measured. If connecting a
current signal to the Model 2001 (AMPS and LO INPUT terminals), select the CURRent input
source. If connecting a voltage signal (HI and LO INPUT terminals), select the VOLTage input
source.
10 OUTPUT 716; ":freq:sour curr; sour?"
20 ENTER 716; A$
30 PRINT A$
40 END
Line 10 Two commands in this program message; the first selects the current input source,
and second queries the input source.
Line 20 Addresses the Model 2001 to talk.
Line 30 Displays the input source (CURR).
