OUTPut Subsystem
The Output subsystem controls the output state, power-on, protection, and relay functions.
OUTPut [:STATe] 0|OFF|1|ON
OUTPut[STATe]?
Enables or disables the output. The state of a disabled output is a condition of zero output voltage and
zero source current. If a Keysight SD1000A SDS is connected, the SDS relays will open when the
output is disabled and close when the output is enabled.
Parameter
0|OFF|1|ON, *RST OFF
Turns the output off: OUTP OFF
When output is enabled, the front-panel status indicator changes from OFF to indicate the oper-
l
ating status of the instrument (CV, CC, etc.).
Separate delays can be programmed for the off-to-on and the on-to-off transition using
l
OUTPut:DELay:RISE and OUTput:DELay:FALL.
Because of internal circuit start-up procedures, OUTPut ON may take 12 milliseconds to complete
l
its function in voltage priority mode, and 14 milliseconds in current priority mode. If a Keysight
SD1000A SDS is connected, the start-up will take longer (see
OUTPut[:STATe]:COUPle[:STATe] 0|OFF|1|ON
OUTPut[:STATe]:COUPle[:STATe]?
Enables or disables output coupling. Output coupling allows the outputs of multiple instruments to
turn on and off sequentially according to their specified OUTPut:DELay:RISE and OUTput:DELay:FALL
programming delays. This parameter is saved in non-volatile memory.
Parameter
0|OFF|1|ON
Turns the output coupling state on: OUTP:COUP ON
You must connect and configure the ONCouple and OFFCouple digital connector pins of all syn-
l
chronized instruments as described in the
Because some power supplies have different minimum delay offsets, you must also specify a com-
l
mon delay offset for all of the synchronized units. This value must be the largest delay offset of the
synchronized group. Use OUTPut:COUPle:MAX:DOFFset? to query the delay offset for each unit.
The largest value returned must be specified as the common delay offset for each unit.
