Querying

Assume that you are using an instrument with the following configuration:

•

slot: 4:1, terminated

•

slot: empty

•

slot: 6:1, unterminated

•

slot: empty

•

slot: 2x 2:1, unterminated

If you query the configuration with the following command:

:SYST:CONF?

You will get the response

0 = 1x4:1*-T; 2 = 1x6:1*-UT; 4 = 2x2:1-UT

As noted earlier, it is recommended to query errors after every command or query, so the complete

set of SCPI commands should be:

:SYST:CONF?
:SYST:ERR?

For the sake of brevity, error queries will be omitted in subsequent examples.

Switching

Assume you want to put the modules into following paths:

•

slot: path 2

•

slot: path 0 (i.e. disconnect all terminals)

•

slot:

◦

relay: path 1

◦

relay: path 2

In order to do so, you could use the following series of SCPI commands:

*RST
:REL:SWIT:PATH "0!.0",2
:REL:SWIT:PATH "2!.0",0
:REL:SWIT:PATH "4!.0",1
:REL:SWIT:PATH "4!.1",2

As mentioned earlier, querying errors after each command (i.e. 5 times total in this example) is

recommended.
