Yes.  It is an optional part of the A.R.C.Type 15D VOR set.
Typically the receiver and the signal data converter both fit in what looked similar to a single two-receiver rack A.R.C. Type E-14.  But if space in the aircraft did not allow that, the receiver could be mounted in rack A.R.C Type E-15 and the converter mounted in rack A.R.C. Type E-16.

The military equivalent of the E-15 is MT-1508/ARN-30A, optional part of AN/ARN-30A, B, and C.

At the moment I have near me only the Operator's Manual for the AN/ARN-30A, 30B, 30C.  It has no schematics.  It should be very easy to trace the circuit, but IIRC the maintenance manual is somewhere on the web.  I'll see if I can find my hard copy over the next few days, but currently my only computer is my smartphone so my scanning capability is out of service.

There should be info on the E-15 or MT-1508 there somewhere.
