V Analyzer
4200A-901-01 Rev. C / February 2017 B-15
Filter
Enables or disables the analog filter:
• Disable: 0
• Enable (can minimize the amount noise in the readings, but increases
measurement time): 1
ReadingRate
The reading rate used to acquire the measurements (0 to 4); see Details
C
Output: The measured capacitance
V
Output: The bias voltage used
G_or_R
Output:
• Parallel measurement model: G_or_R is the measured conductance
• Series measurement model: G_or_R is the measured resistance
Details
This user module is used to make a single, fixed-bias capacitance and conductance measurement.
The default parameters for the 590-cmeas UTM, which uses the Cmeas590 user module, are shown
in the figure below.
Figure 560: Cmeas590 (cmeas UTM parameters)
In general, the 590 is set to source 5 V for 2 seconds, then make a measurement, as shown in the
following figure.
