Sequencing the Output
This section describes how you can synchronize output turn-on and turn-off sequences on single and
multiple units.

Output Turn-On/Turn-Off Behavior
Turn-On/Turn-Off Delays
All power supplies exhibit an internal delay offset that applies from the time that a command to turn on
the output is received until the output actually turns on. Specifying a common delay offset serves as a
reference point for any user-programmed turn-on delays. This user-defined offset also makes it
possible to connect multiple power supplies together and program accurate turn-on sequences
across multiple outputs. The user-programmed turn-on delay will then be added to the common user-
defined reference point.
There is no need to specify a common delay offset when outputs turn off. Outputs start executing their
turn-off delays as soon as an Output Off command is received. The internal delay offset is shown in the
following table.
Models Voltage Priority Current Priority
N6914xA ≤ 12 milliseconds ≤ 14 milliseconds
N6917xA ≤ 8 milliseconds ≤ 7 milliseconds
Coupling the Output
In addition to the front panel and SCPI Output On and Output Off commands, you can also use
OnCouple and OffCouple signals to enable and disable the output. These signals provide an additional
level of control when sequencing the output on individual and multiple units.
The following figure illustrates the programming path when using the OnCouple and OffCouple signals
to control the output.
