Create complex, multi-level sequences of output changes.
Create output changes that have rapid or precise timing requirements.
The following power source functions are subject to transient control:
AC output current
AC output current phase shift
DC output current
Start phase angle
AC and DC current slew rate
The following transient modes can be generated using the Sequoia Virtual Panels GUI or SCPI commands:
Step Generates a single triggered output change.
Pulse Generates an output change which returns to its original state after a specified
time.
List Generates a sequence of output changes, each with an associated dwell time or
paced by triggers.
Fixed Turns off the transient functions; with SCPI commands, only the IMMediate values
are used as the data source for a particular function.
Figure 8-15 shows a representation of programming changes in the transient modes, and the output
waveform that is generated in each mode.
When a trigger is received in Step or Pulse modes, the triggered functions are set from their SCPI
command, IMMediate, to their TRIGgered value. In Step mode, the triggered value becomes the
immediate value. In Pulse mode, the functions return to their immediate value during the low portion of
the pulse. If there are no further pulses, the immediate value remains in effect. In List mode, the functions
remain at the last list value at the completion of the list. STEP, PULSe, and LIST modes are not allowed
to be mixed among functions.
