CVU Terminal Settings Advanced settings and circuits
You can apply AC drive voltage and DC bias voltage to either the CVH1 terminal or the CVL1
terminal. To change the options, select the
Terminals Settings
pane, then select
Advanced.
By default, AC source voltage is applied to the CVH1 terminal and the current measurement is made
at the CVL1 terminal. Also by default, the DC source voltage (bias) is applied to the CVL1 terminal.
The settings and test circuits are shown in the following figures.

You can change the configuration to source AC voltage to CVL1 and DC source voltage to CVH1
while measuring AC current at CVH1, as shown in the following figure.
