Configuring Dynamics Settings (Tuning) - Scanlab RTC 5 PC Interface Board Installation And Operation Manual

monitoring XY positioning because it's only
meant for querying a single signal and multiple
calls unavoidably lead to XYZ values across
different points of time.
• With set_trigger, you can simultaneously record
two desired signals via two measurement
channels (with set_trigger4
measurement channels).
• With transform and get_transform, you can use
the parameter Code to specify that values queried
via get_values or set_trigger
to X, Y and Z for backward transformation.

performed.
• Values queried via get_values, or arbitrary
synthetic values (e.g. measurement points of a
scanned test pattern) can actually be backward
transformed with transform. During backward

extrapolation, due to possible range violations or
other errors.
• If the application binarily stores both the
recorded values and the transferred transfor-
mation data (see get_waveform), then subse-
quent backward transformation via
(not get_transform) can also be executed offline,
hence without needing to further access a RTC
board.
• If control_command is used to specify
positioning error rather than actual position as
the to be returned data type by the scan system,
then it isn't possible to directly compare the origi-
nally defined pattern with the scanned pattern.
But you can check if the scan system correctly

processed the RTC 5 board's output values. This
is particularly useful if backward transformation
of actual values isn't (fully) possible or when it
can't be determined if deviations between
backward-transformed actual positions and origi-
nally defined coordinate values are due to scan
system error or clipping during forward transfor-
mation.
