[NLRS] Looking for connectors or cable

[Dr. Gerald N. Johnson]

An HP X347A waveguide noise generator arrived yesterday. Now I'm looking 
for the mating Cannon connectors or HP cable.

The connectors of the cable (340A-16A) are Cannon GK-R7-21C-1/2 (female) 
and GK-R7-22C-1/2 (male). Could have the suffix 5/8 which is the size of 
the cable clamp. These have 7 pins and are about 1-1/2" diameter with an 
acme thread. HP Part numbers 1251-0081 and 1251-0080. I have an HP340A 
that with new filter capacitors and a few tubes could supply the noise 
generator or I have a home brew NF supply that has new capacitors and 
uses another connector which I have, so the female would be most useful, 
otherwise I'll cobble something in a 6 pin cinch jones.
