This slide shows an example setup of the GPIB I/O statement. This is a component of the test
contents used to control the Agilent B2200 switching matrix.
This example uses the Write Value function to send the following command to the B2200.
:ROUT:SYMB:CHAN {0},{2},”{1}”
where, {0} is CardNo, {1} is StringCh, and {2} is ChanNo.
The followings are the reference of the setup editor.
•Address: GPIB address of the device
•Terminator: EOI, LF, CR/LF, LF+EOI, CR/LF+EOI, or NONE (no terminator)
•Format: Command (header and parameters) sent to the device
•Value 1: Value for {0}
•Value 2: Value for {1}
•Value 3: Value for {2}
•Value 4: Value for {3}
{0}. {1}, {2}, and {3} are variable available in the Format field only.
