Sequence Multiple Outputs
Turn-on and turn-off delays control the power-up and power-down sequencing of the output channels
in relation to each other.
Front Panel Menu Reference SCPI Command
Press the Channel key to select an output. Then select
Output\Sequence\Delay.
Select either Turn-on delay or Turn-off delay. Enter a delay in
seconds. Then press Select.
Select System\Preferences\Keys. Check On/Off key affects all
channels. Then press Select.
To program a 50 ms turn-on delay for output 1 and a 100
ms turn-on delay for output 2:
OUTP:DEL:RISE 0.05,(@1)
OUTP:DEL:RISE 0.1,(@2)
To program a 200 ms turn-off delay for outputs 3 and 4:
OUTP:DEL:FALL 0.2,(@3,4)
Output turn-on characteristics vary across the power module types - DC Power, Autoranging,
Precision, and Source/Measure. When output channels of the same module type are programmed off-
to-on, output sequencing is determined by the programmed turn-on delays.
When outputs of different module types are sequenced, there may be additional offsets of a few
milliseconds from one output to another that must be accounted for. Specifying a common delay offset
assures that the programmed turn-on delays will be synchronized to start at the completion of the
common delay offset. Select the delay offset of the slowest power module in the mainframe and use
that as the common delay offset. (See Synchronizing Output Turn-On for more information.)
Front Panel Menu Reference SCPI Command
In the front panel menu, select Output\Sequence\Couple.
Max delay offsetfor this frame displays the delay offsetof the
slowest power module in the frame. Enter this value into the
Delay offsetfield in milliseconds. Then press Select.
To query the delay offset of the slowest power module
in the mainframe (the maximum delay offset):
OUTP:COUP:MAX:DOFF?
To specify the common delay offset for the mainframe:
OUTP:COUP:DOFF 0.051
Program the Output Relays
Output relay availability and options are described under Options. provides double-pole,
double-throw relays that disconnect both the output and sense terminals. is the same as
option 761 but adds output reversal relays. Note that a small AC network is always present across the
output terminals.
Front Panel Menu Reference SCPI Command
Not Available To leave the relays closed when output 1 is turned off:
OUTP OFF,NOR,(@1)
To leave the relays open when output 1 is turned on:
OUTP ON,NOR,(@1)
