Programming examples

These programming examples provide examples of how to use LPT commands to:
•
Make a single CsRs impedance measurement:
•
Do a single staircase sweep and measure CpGp for each step:
page 13-195)
•
Do a single frequency sweep and measure CpGp for each step:
page 13-196)
•
Do a voltage array sweep:
•
Do a voltage array sweeps with an array of delay values used for the sweep:
example #5
Programming example #1
Performs a single CsRs impedance measurement. Test parameters:
•
DC bias voltage = 1 V
•
AC drive frequency = 100 kHz
•
AC drive voltage = 15 mV
•
Measure model = CsRs
This example also acquires a timestamp for the measurement.

/* Set DC bias to 1 V. */
/* Set AC drive frequency to 100 kHz. */
/* Set AC drive voltage to 15 mV RMS. */
/* Set settling time to 100 ms. */
/* Select 1 mA measure range. */
/* Return timestamp for measurement. */
/* Reset CVU. */
