AUX INPUT and OUTPUT COMMANDS

OAUX? i

AUXM (?) i {, j}

AUXV (?) i {, x}

SAUX (?) i {, x, y, z}

TSTR (?) {i}

The OAUX? command queries the Aux Input values. The parameter i selects an Aux Input (1, 2, 3 or 4) and is required. The Aux Input voltages are returned as ASCII strings with units of Volts. The resolution is 1/3 mV. This command is a query only command.

The AUXM command sets or queries the Aux Output mode. The parame- ter i selects an Aux Output (1, 2, 3 or 4) and is required. The parameter j selects Fixed (j=0), Log sweep (j=1) or Linear sweep (j=2).

The AUXV command sets or queries the Aux Output voltage when the output is in fixed voltage mode. The parameter i selects an Aux Output (1, 2, 3 or 4) and is required. If i selects an output which is set to sweep, then the AUXV command will generate an error. The parameter x is the output voltage (real number of Volts) and is limited to -10.500 x 10.500. The output voltage will be set to the nearest mV.

The SAUX command sets or queries the Aux Output sweep limits and offsets. The parameter i selects an Aux Output (1, 2, 3 or 4) and is required. If i selects an output which is set to fixed voltage mode, then the SAUX command will generate an error. The parameter x is the sweep start voltage. The parameter y is the sweep stop voltage. The parameter z is the sweep offset voltage. The parameters x, y and z are real numbers of Volts. The values of x and y are limited to 0.001 x,y 21.000. The value of z is limited to -10.500 z 10.500. The voltages will be set to the nearest mV.

The SAUX? i query will return x,y,z if the output is in a sweep mode. The return string is in ASCII and multiple parameters are separated by commas. For example, the SAUX?1 command returns "3.456,7.890,0.000" if output 1 is sweeping from 3.456V to 7.890V with 0.000V offset.

Any set of sweep parameters which would result in an output voltage out- side of the -10.5VV10.5V range results in an error.

The TSTR command sets or queries the trigger start scan mode. The parameter i selects No (i=0) or Yes (i=1).
