Details
This user module performs cable compensation for the selected ranges and test frequencies of the
590. The figure below shows the default input parameters for a UTM that uses the
CableCompensate590
user module.
Figure 559: CableCompensate590 default parameters
If the default parameters are used, cable compensation is done for the 2 pF, 20 pF, 200 pF, and 2 nF
ranges and for the 100 kHz and 1 MHz test frequencies. The line 1 input parameter indicates the
directory path where the user-input capacitor source values are saved. These values are entered and
saved using the
SaveCableCompCaps590
user module.
Test example 1 demonstrates how to do cable compensation (see
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
.
Returned values are placed in the Analyze sheet.
