Aux Input and Output Commands
OAUX? [ j ]
The OAUX? j query returns an aux input voltage. The parameter j (0 – 3) selects aux input
1 – 4 on the rear panel.
Example
OAUX? 0 Returns the aux in1 voltage v
OAUX? 1 Returns the aux in2 voltage v
AUXV(?) [ j ] { , v { NV | UV | MV | V } }
The AUXV? j, v command sets an aux output to voltage v. The parameter j (0
–
3) selects
aux output 1 – 4 on the rear panel. The voltage v can be set from – 10.5 V to +10.5 V.
Example
AUXV 2, 678.9 MV Set aux out3 to 678.9 mV
AUXV 2, 6.789E-1
AUXV 2, 0.6789
AUXV? 2
Returns the aux out3 voltage setting in Volts
