Interface Specs
Main line Diameters and center conductor setbacks per Bird
drawings.
Connectors One DB9(M), three N(F)
DB9 connector pinout
Pin 1 = “FWD” Analog output for forward RF power. 0 – 5.0 Vdc
proportional to RF power, 1 kohm
impedance. Fullscale RF input = 4.0V output.
Pin 3 = “RFL” Analog output for reflected RF power. 0 – 5.0 Vdc
proportional to RF power, 1 kohm
impedance. Fullscale RF input = 4.0V output.
Pin 5 = “Power” Power supply input. +11 to +18 Vdc, < 0.1 A.
Pin 9 = “Zeroline” Short this pin to ground to zero out any input offsets.
Normally floating. Unit can be zeroed whenever the unit is
powered up and there is no RF power being applied.
Pins 2,4,6–8 = GND
N(F) Testports Ports are labeled Forward, Test, and Reflected. Forward
and reflected testports include attached loads. These
testports must be terminated with the load, or some other
good termination such as a power sensor, during normal
operation to prevent measurement errors. Loads can
removed from the unit if desired without affecting calibration.
Forward Testport output is a sample of the forward RF signal.
Test Testport output is a nondirectional sample of the RF.
Reflected Testport output is a sample of the reflected RF signal.
