Hello All,
As the rain-scatter season is here I am again working to improve my
10g system. My current project is to get my WJ TWT online.. I need
information in regards to the power supply and general instructions on
its operation.. First, this power supply has a 12 pin military
quick-connect plug for the power supply input and control. I am needing
information on what pins go to what.. Obviously two of them are the 120
volts AC input.. The power supply output connector mates to the TWT and
should require no information..
Here is what I know of this unit so far..
The TWT is labeled:
Watkins Johnson TWT type WJ3075, Spec No.: 6633-2/72
TWT 3372...
Freq Range 7 - 11 Ghz, Gain 43 - 48 db.
Saturated Power +34 - +38dbm...
Power Supply is labeled:
WJ 1200-5 ,
Spec. No.: 6633-2/72 UPS 3370
Input 115 Vrms, 400 Hz, 1.3 Amp.
I have a 400 Hz 120 volt inverter ready to use with this unit.
Any help with this "Beasty" would sure be appreciated..
73's, Al
