Newport XPS-D Programmer's Manual

XPS Unified Programmer’s Manual
Signal is generated with a random value at with a period defined by the controller
base time (CorrectorISRPeriod , default value 0.125 ms), then is filtered with a
second order low-pass filter at the cut-off Frequency value.
- Random-pulse-width binary-amplitude signal mode:
Amplitude (>0 and ≤Limit), Time (≥4 * CorrectorISRPeriod), Frequency (≥0.1 and
≤0.5/CorrectorISRPeriod).
Signal is a sequence of pulses (Signal = Amplitude or = 0) with pulse randomly
varied width (multiple of Tbase).
Frequency is the controlled system band-width (cut-off frequency), necessary for the
PRBS (Pseudo Random Binary Sequence) function configuration.
The function non-effective parameters can accept any value, the value 0 is
recommended for simplicity.
NOTE
If during the excitation signal generation the stage position exceeds the user
minimum or maximum target positions, the motor excitation command is stopped
and an error is returned.
NOTE
This function does exactly the same that the function
PositionerExcitationSignalSet() does, with only one difference between them. The
difference is that, with the function PositionerExcitationSignalCorrectorOutSet(),
the generated excitation signal is inserted at the corrector output, that can be
useful in some cases, like the measurement of robustness transfer function.
