Details
This user module is used for 590 cable compensation. You enter precise capacitance source values.
When this test is run, the capacitance source values are saved to a user-specified file. The user
module to perform cable compensation (
CableCompensate590
) can then access the capacitance
source values from this file.
The default parameter values for this user module are shown in the following figure. These are
suggested low and high values that can be used for cable compensation. You must replace these
values with the calibration values of the capacitance sources.
Figure 569: save-cap-file action and SaveCableCompCaps590 user module
(on page B-6) demonstrates how cable compensation is done.
If the file defined for
CabCompFile
does not exist, or there is no path specified (null string), the
default compensation parameters are used. When entering the path, use two backslash (
\\
)
characters to separate each directory. For example, if your cable file is in
C:\calfiles\590cal.dat
, you enter the following:
C:\\calfiles\\590cal.dat
If a switch matrix to route signals is being controlled by a connection action (for example,
connect
),
there is no need to connect
InputPin
and
OutPin
. Set these parameters to
0
.
