SCPI Commands for Digital Interfaces

To check the setting:

OUTP:AUXA:SOUR?

To set up Auxiliary line B:

OUTP:AUXB:SOUR <aux-line-mnemonic>

To set the polarity of the auxiliary status lines:

OUTP:AUXA:POL {HIGHLOW}

OUTP:AUXB:POL {HIGHLOW}

Where:

HIGH means that the logic of the output is active high. (That is, if the condition is true, the line is pulled high.)

LOW means the logic of the output is active low.

The user can select polarity for either of the auxiliary lines.

To check the state of the line:

OUTP:AUXA:STAT?

This command returns a 1 or 0. If it returns a 1, this means that the status selected as the auxiliary line mnemonic is true.

Read Error To read from the error queue:

Messages SYST:ERR?

This command returns an error code and message from the error queue. For example:

-315, “Configuration memory test”

-100, “Command error”
