smeasvRT
This command returns the sourced DC bias voltages (in real time) for a sweep.
Usage
int smeasvRT(int
instr_id
, double *
varray
, char *
colname
);
instr_id
The instrument identification code of the 4210-CVU:
CVU1
varray
Returned array of DC bias voltages
colname
Column name to pass into Clarius (character string)
Details
This command is similar to
smeasv
command. It returns the sourced DC bias voltages for a sweep in
an array. However, the voltage values are posted to the Clarius Analyze sheet and graph in real time.
Each voltage value appears in the sheet and graph after each step of the sweep is executed.
Note that the values are only available in real time if Clarius is running. Otherwise, they are stored in
an array.
The
colname
parameter specifies a name for the data sheet column in Clarius.
Example
smeasvRT(CVU1, volt_arr, "volt_arr");
This command posts the voltage values into the Clarius data sheet under a column named
volt_arr
.

smeasz
This command performs impedance measurements for a sweep.
Usage
int smeasz(int
instr_id
, long
model
, long
speed
, double *
result1
, double *
result2
);
instr_id
The instrument identification code of the 4210-CVU:
CVU1
model
Measure model; refer to "Measurement model parameter values" table in the
Details
speed
Speed settings:
•
KI_CVU_SPEED_FAST
: Fast measurements (higher noise)
•
KI_CVU_SPEED_NORMAL
: Selects a balance between speed and low noise
•
KI_CVU_SPEED_QUIET
: Low-noise measurements
•
KI_CVU_SPEED_CUSTOM
: Selects custom settings; the delay factor, filter
factor, and aperture are set using the
setmode
command
result1
Array of the first result of the selected measure model
result2
Array of the second result of the selected measure model
