If you want to run your test procedure on a station that has a dual compensation
control mode in which the compensation type is Mean and Amplitude Control,
you may disable the setpoint without any adverse effect.
For more information about how the setpoint control is affected by dual
compensation control modes, see the 793 Control Software manual (PN 100-147-
130).
About Command Hold and Stop Behaviors
The Command Hold Behavior and Command Stop Behavior functions allow
you to specify how an active MPT command process behaves when a procedure
transitions to the hold or stop states.
The following selections are the same for each control:
•
Stay at Level—The waveform holds/stops at the current level.
•
Ramp to Mean—The waveform ramps to mean.
•
Ramp to Zero—The waveform ramps to zero.
•
Taper to Mean—The waveform tapersto mean.
•
Taper to Zero—The waveform tapers to zero.
The transition times for all ramp and taper functions are specified using the
Command Options tab on the Station Manager’s Channel Options window. The
default transition time is two seconds.
For more information about specifying command options, see the MTS 793
Control Software manual.
Special consideration
If the procedure ends normally, and the Command Stop Behavior is set to
Ramp to Mean or Taper to Mean, the signal may not respond as you expect.
When a procedure ends normally (without being manually held or stopped), all of
its processes end normally, and then the Command Stop Behavior is run. In
these situations, Ramp to Mean and Taper to Mean settings behave like a “stay
at level” setting, and the Taper to Zero setting behaves like a “ramp to zero”
setting. The Ramp to Zero setting works as expected.
