Hi Harry:

It's my recollection that PM made diode type detectors rather than bolometers.

You might check to see of the sensor mates with a Pacific Measurements scalar 
network analyzer.  They are similar to the HP 8756 8757 scalar NAs.  If you you 
might find a used PM SNA and make much better use of the sensor.   All that if 
the sensor is good.

If it fits the PM SNA then you should be able to find a manual for the SNA that 
might have information on the connector pin out.

Have Fun,

The cable didn't mate to the 432 but the guy selling it said that I could get a correct mating connector and rewire it.
