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
dependability.
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.
