Waveguide-models Information

The waveguide power sensors (excluding Option CFT) measure power
levels from –35 dBm to +20 dBm at frequencies from 26.5 GHz to 50 GHz.
They consist of a multi- stepped coax which adapt the 50 W thermocouple
impedance to the desired waveguide impedance, and hence provide a very
low SWR up to 40 or 50 GHz.

prevent the sensor from being connected to a high power source when an attenuator is
not attached. The sensors must only be connected to the power meter for calibration or
to a high power attenuator for any RF measurements.
