cvu-capacitor connections
The test configuration is shown in the next figure. Use only the supplied (red) 100 Ω SMA cables for
connections to the 4210-CVU. Be sure that all SMA cables are the same length.
After making or changing connections, be sure to use the Confidence Check diagnostic tool and do
connection compensation tests. Refer to
(on page 4-10) for details.

Formulas and constants
This project uses one formula with no constants.
•
NOISE: Calculates the standard deviation of the capacitance measurements:
NOISE = STDEV(CP_AB)
cv-10 pF test
This test performs a voltage sweep that measures capacitance on each step and generates a C
versus V graph. It also calculates noise.
Analyze sheet
Test data is displayed in the Analyze sheet:
Cp_AB
Measured parallel capacitance.
Gp_AB
Measured conductance.
DCV_AB
Forced DC bias voltage.
F_AB
Forced test frequency.
CVUS1
Status code for each measurement. Rows highlighted in blue indicate a
fault. For details, see
(on page 6-191).
NOISE
Formulator calculation result.
NOTE: AB = Terminal A to Terminal B.
