Precision Dial Gauge Attenuators
These precision calibrated
variable waveguide attenuators provide a highly accurate, stable means of
adjusting or measuring attenuation in a waveguide system. They are widely
used in laboratory application providing accurate measurements with long life
A bilaterally matched parallel type attenuator element is positioned within the waveguide section by means of an ultra-precise mechanism which is absolutely free of backlash or play. Precision dial gauges are utilized to indicate the exact relative position of the attenuating element in the waveguide section. Special attention has been given in the design of the instruments to provide shielding against leakage.
A single frequency calibration at 5 dB points throughout the attenuation range of the instrument is provided at the frequency specified in the chart. A calibration curve showing dial reading versus attenuation is supplied with each instrument. Additional calibrations may be obtained on special order. Alternate flanges and materials are available. See flange section. Finish is instrument gray enamel.
