:SOURce[1]
:VOLTage
[:LEVel]
[:IMMediate]
SOURce1 subsystem:
Path to voltage source commands.
[:AMPLitude]
<NRf>
Set voltage source amplitude (-500 to
500).
1
0
[:AMPLitude]?
Query voltage source amplitude.
:RANGe <NRf>
Set source range (10, 50, or 500[V]).
10
2
:ILIMit <NRf>
Set source current limit (2.5e-5 to 2.5e-2[A]).
3
2.5e-2
:STATe <b>
Enable or disable source output.
4
OFF
:STATe?
Query source output state.
:INTerlock
Path to control interlock:
[:STATe] <b>
Enable or disable interlock for 10V range.
5
OFF
[:STATe]?
Query interlock state.
6
:FAIL?
Query interlock status (1 = interlock
asserted).

1.
If voltage source is in operate, value will be updated immediately. Value cannot be set above voltage source range.
2.
Default for DDC mode (see
) is 50V.
3.
Limit settings are: 25
μ
A, 250
μ
A, 2.5mA, and 25mA; current limit will be set to closest programmed value. For the 500V and the
50V ranges, the maximum ILIMit is 2.5mA (0.0025A). On the 10V range, any of the four current limit choices can be selected.
The default 10V Ilimit is 25mA or 2.5mA in DDC mode (see
).
4.
STATe ON places source in operate.
5.
Ignored for 50V and 500V ranges since interlock is always enabled. Attempting to turn off the interlock state while on the 50 or
500V range will generate a “-221 Settings Conflict” error. Upranging from the 10V range will always cause the interlock to be
enabled. When the unit returns to the 10V range, the interlock state will be reset to the state it had when the unit left the 10V range.
6.
Querying the interlock state while on the 50V or 500V range will always return TRUE.
7.
Asserted interlock indicates that voltage source cannot be placed in operate.
