Performance

Verification

Tests

These programs are designed to do the Performance Verification Tests

found in Chapter 2 - Verification Tests.

NOTE

These programs assume a primary address of 09 and a secondary address

of 14. If your FET Multiplexer address does not match this, you must either

change the FET Multiplexer address setting or change the program lines

#define ADDR "hpib7,9,14" to match your FET Multiplexers address

setting.

Example: Closed

Channel

Resistance Test

This example performs a closed channel resistance test of all measurement

paths. If a FET on resistance is >3.1 kΩ , the program prints a message

indicating which channel has failed. Before the closed channel

measurement, the program checks for stuck channels. If a stuck channel is

found, the program prints a message and halts.

#define ADDR "hpib7,9,14" /* Address of device */

#define DMM "hpib7,22"
