Standard Products

Direct Reading Attenuator (DRA) - A calibrated, frequency independent, and waveguide direct reading attenuator device, suitable for both instrumentation and calibration applications. Available from 26.5 to 170 GHz in eight waveguide bands. Features low VSWR and small variation in phase shift over frequency.

Direct Reading Frequency Meter (DRF) - Offered in eight waveguide bands covering 26.5 to 166 GHz. Consists of a TE111 mode cavity resonator. The calibration is scaled around a drum dial that indicates frequency by noting the dip in detected power transmitted through the meter.

Direct Reading Phase Shifter (DRP) - Offered between 26.5 and 170 GHz in eight waveguide bands. These broadband instruments provide precise variable phase shift over the full frequency band with low insertion loss and VSWR. Consist of rectangular-to-circular waveguide transitions with mode suppressors, and a rotary phase shift vane.

Motorized Waveguide Attenuator (MWA) - Offered in nine waveguide bands covering 18 to 170 GHz. Consists of a rotary vane device and a controller. Attenuation is controlled by GPIB or RS-232C interface. The heart of the controller is a microprocessor that drives an accurate stepper motor to achieve the desired attenuation.
