Smeaszrt - Keithley 4200A-SCS Reference Manual

Model 4200A-SCS Parameter Analyzer Reference Manual

smeaszRT

This command makes and returns impedance measurements for a voltage or frequency sweep in real time.
Usage
int smeaszRT(int instr_id, long model, long speed, double *result1, char *colname1,
double *result2, char *colname2);
instr_id
model
speed
result1
colname1
result2
colname2
Details
This command is similar to the smeasz command; both commands return the measured impedance
readings for a sweep returned in arrays. However, the readings from smeaszRT are posted to the
Clarius Analyze sheet and graph in real time. Two measurement results appear 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 colname1 and colname2 parameters specify names for data sheet columns in Clarius.

Example
smeaszRT(CVU1, 2, KI_NORMAL, result1, "result1", result2, "result2");
This command posts the results into the Clarius data sheet under columns named result1_arr and
result2_arr.

Measure model (see "Measurement model parameter values" table in Details)
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
