Appendix F – Performance Verification
Procedure
The performance verification procedure for the 73A-308 Relay and High Voltage Driver
Module verify that the module is operating within specification.
Conventions Used In This Procedure
All control of the 73A-308 Module will be accomplished through a VXI Slot 0 device.
ASCII characters will form the commands sent to control the module and ASCII characters will be read from the module.
Throughout this document writes to the 73A-308 Module will be shown as:
Send “QER
where QER
lf”
lf is the command (Query the ERror) terminated with a linefeed character (lf).
Commands will be sent exactly as shown.
Reads from the module are shown as:
Read “NO ERRORS
where NO ERRORS
nated with a carriage return and linefeed (
crlf”
crlf is the ASCII string returned from the 73A-308 Module, termi-
crlf). The ASCII string returned from the mod-
ule will be exactly as shown.
Unless noted, all commands are sent to the 73A-308 Module and all ASCII strings read
are read from the 73A-308 Module.
Two characters are used throughout the communication sequences: “
return character (character 13) and “
lf” is the line feed character (character 10). These
cr” is the carriage
characters are the terminating characters for communication. They are shown throughout
this document in the font shown here. Most reads from the 73A-308 Module are terminated with both characters and are shown as “
“
lf”, but both characters may be used.

An ASCII upper case letter “O” will be shown as “O” whereas a ASCII zero will be
shown as “0”.

Triggering
This tests the TTLTRG lines on the VXI backplane.
Steps 2 through 8 verify that the output will not go active until a trigger is received on the
selected TTLTRG line. The test uses Relay Output 72 and a 300 mA current supplied by
a +5V power supply.
Step 3 programs the Trigger Setup to use TTLTRG 0 as the input trigger line that activates Relay Driver 72. The command also sets TTLTRG 0 as the output line. This line
will output a trigger pulse on the Trigger command (step 6). Since TTLTRG line 0 is used
as both the input and output, the output trigger pulse will be the trigger input pulse that
activates Relay Driver 72.
Steps 3 and 4 ensure that the driver is not active until the trigger command is received in
step 6.
Steps 8 through 14 test that only the selected TTLTRG input line will cause the output to
go active. Step 9 programs the Trigger Setup to use TTLTRG 0 as the input trigger line
that activates Relay Driver 72 and TTLTRG 1 as the output line.
Steps 2 through 14 test TTLTRG line 0 for input.
