forcev
This command sets the DC bias voltage level.
Usage
int forcev(int
instr_id
, double
voltage
);
instr_id
The instrument identification code of the 4210-CVU:
CVU1
voltage
DC bias voltage level (
−
30 V to 30 V)
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
(on page 13-194) makes a single impedance measurement. Note that the
rdelay
command provides a settling time before the measurement.
