PostDataString

This command transfers a string from memory into the Clarius Analyze sheet in the user test module and plots it

on the graph.

Usage

PostDataString(char *variableName, int *variableValue);

variableName

The variable name

variableValue

The value of the variable to be transferred

Details

The first parameter is the variable name. For example, if the output variable name is DrainI, then

DrainI (with quotes) is first parameter.

The second parameter is the value of the variable to be transferred. For example, if DrainI[10] is

transferred, then you call PostDataString("DrainI", DrainI[10]).

rdelay

This command sets a user-programmable delay.

Usage

int rdelay(double n);

The delay duration in seconds

Example

double ir4;

conpin(SMU1, 1, 0);

conpin(GND, 2, 0);

forcev(SMU1, 60.0); /* Generate 60 V from SMU1. */

rdelay(0.02); /* Pause for 20 ms. */

measi(SMU1, &ir4); /* Measure current; return */

/* result to ir4. */

This example measures the leakage current of a variable-capacitance diode. SMU1 presets 60 V across

the diode. The device is configured in reverse-bias mode with the high side of SMU1 connected to the

cathode. This type of diode has high capacitance and low-leakage current. Because of this, a 20 ms delay

is added. After the delay, current through SMU1 is measured and stored in the variable ir4.
