I do not think this is correct. The IRIG almost certainly refers to the Apollo Inertial
Reference Integrating Gyro, which you can see in this video along with one of the PSA
trays Adrian?s contraption is supposed to be testing:

BTW I got my Apollo IRIG at the same auction that Adrian got the Apollo PSA tester from.

There's a switch labeled "IRIG" which stands for Inter Range
Instrumentation Group, and refers to a standard for
telemetry encoding. There is a standard for time code, a
standard for modulating analog signas onto a bunch of FM
carriers, and a standard for multiplexing several analog
signals onto one FM carrier.
Apollo documents are probably VERY hard to come by these days.
