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 charac-
ters will be read from the module.
Throughout this document writes to the 73A-308 Module will be shown as:
Send “QER
lf
”
where QER
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
crlf
”
where NO ERRORS
crlf
is the ASCII string returned from the 73A-308 Module, termi-
nated with a carriage return and linefeed (
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: “
cr
” is the carriage
return character (character 13) and “
lf
” is the line feed character (character 10). These
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 termi-
nated with both characters and are shown as “
crlf
”. Writes to the module require only a
“
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”.
