Enter and save capacitance source values (save-cap-file)
To enter and save the capacitance source values:
1. Select Configure.
2. In the project tree, select save-cap-file. The default parameters for the user module are
displayed, as shown in the following figure.

3. Enter the capacitance source calibration value for each range and frequency. If you are using the
5909, each capacitor has a label indicating the calibration value at 100 kHz and at 1 MHz.
For example, assume the low capacitance source for the 2 pF range is 0.47773 pF (100 kHz) and
0.47786 pF (1 MHz). Enter these values using scientific notation:
▪ Lo2p100k: Enter 0.47773e-12
▪ Lo2p1M: Enter 0.47786e-12
4. In the project tree, select the action.
5. Click Run to execute the action.
