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.
