Attenuators
Attenuators
It is constructed from cylindrical cavity resonator with a variable short circuit termination. The shorting plunger is used to change the resonance frequency of the cavity by changing the cavity length. DRF measures the frequency directly. It is particularly useful when measuring frequency differences of small changes.
Variable attenuators
These attenuators provide continuous attenuation power upto 20 dB.
