In general, the 590 outputs a linear staircase voltage sweep from −4 V to +6 V in 50 mV steps. As
shown in the following figure, a capacitance measurement is made on each step of the sweep. A test
example demonstrates how to perform a C-V sweep (see Model 590 test examples (on page 4-6)).

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.
For Range, the measurement range values are shown in the following table.
