[SFDXA] Searching for info about Power Sensor

[Kai]

I am looking for hook-up information for a Thruline Power Sensor that I picked 
up at an estate sale. The specs are:
Thruline Power Sensor Model 4142B
RFL power 1200 W
FWD power 1200W
2-30 MHz frequency range.

The unit has two RF connectors for the thru-line RF power, plus two additional 
BNC outputs (F and R) signal from internal sensor diodes. I need to know how the 
dc voltage/current on those BNC ports relates to the F and R power.

The unit looks like the the picture of the Bird 4192-010 Thruline Power Sensor 
225-400 MHz 50 WATTS
when you search e-bay for "Bird-4192-010-Thruline-Power-Sensor"

Any help will be appreciated.
