forcev

This command sets the DC bias voltage level.
Usage
int forcev(int instr_id, double voltage);
instr_id
voltage
Details
This command sets a DC bias level for a single impedance measurement and a frequency sweep.
Use the setfreq and setlevel commands to set the AC drive frequency and AC voltage for the
sweep.
The DC source operates independently of the AC source. Changes to the level and state of the DC
source take effect immediately; the AC frequency and source value are only used during measz
operations.
Example
Programming example #1
rdelay command provides a settling time before the measurement.
