apollo psa test point adaptor

[Curious Marc]

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.
