Aux Input and Output Commands
AUXI? i
The
AUXI?
command queries the Aux Input values. The parameter
i
(
1
or
2
)
selects an Aux Input and is required. The Aux Input voltages are returned in units
of Volts. The resolution is 1/3 mV. This is a query only command.
AUXO(?)i{,x}
The
AUXO
command sets or queries the Aux Output voltage. The parameter
i
(
1
or
2
) selects an Aux Output and is required. The parameter
x
is the output
voltage (real number of Volts) and is limited to –10.500
≤
x
≤
10.500 .
