KXCI command: :CVU:MEASZ?
Purpose: Triggers and returns single Z-measurement using current CVU settings. When the command
System Mode
KXCI command: :CVU:SOAK:DCV voltage
Purpose: Sets the presoak DC voltage for CVU card for ALL sweeps (that is, frequency sweep, DC
Parameters: voltage: Voltage to bias before test sequence begins. Voltages range from -30 V to +30 V.
KXCI command: :CVU:BIAS:DCV:SAMPLE biasv, samples
Purpose: Configures the CVU to bias a DC voltage and sample n Z-measurements for the CVU card.
Parameters: biasv: Voltage to source while sampling Z-measurements. Voltages range from -30 V to +30
KXCI command: :CVU:SWEEP:FREQ fstart, fstop, <order>
Purpose: Configures the CVU to sweep frequency and sample Z-measurements for the selected CVU
Parameters: fstart: The frequency that is used for capturing the initial sample in the sweep.
KXCI command: :CVU:SWEEP:DCV dcvstart, dcvstop, dcvstep
Purpose: Configures the CVU to sweep DC voltage and sample Z-measurements for the selected CVU
Parameters: dcvstart: start voltage

parameters are set by their respective commands.
fstop: The frequency that is used for capturing the final sample in the sweep.

Values are coerced to one of the 28 discrete frequencies or 37
discrete frequencies for the 4200-CVU and 4210-CVU, respectively.
The other parameters (AC voltage level, frequency, and so on) are
set by their respective commands. Valid voltage levels are -30 V to
+30 V.
