Performance
Verification
Test
This program is designed to do the Performance Verification Test found
in Chapter 2 - Verification Tests.
NOTE
These programs assume a primary address of 09 and a secondary address
of 14. If your Multiplexer address does not match this, you must either
change the Multiplexers address setting or change the program lines
# define ADDR "hpib7,9,14" to match your Multiplexers address setting.
Example: Closed
Channel
Resistance Test
This example performs a Closed Channel Resistance Test to measure
Channels 00 - 47, Channels 90 - 92, cna Channel 93 HI, LO, and GU
relay contact resistances. If the relay contact resistance for a channel is
> 2.0W, the program prints a message indicating which channel has
failed the test. on all channels in the RF Multiplexer. If a channel is out
of specification, the program prints a message and pauses.
