Direct Reading Attenuators
These variable attenuators
are direct reading precision calibrated units which provide a range of
essentially 0 to 40.0 dB with a maximum VSWR of 1.15 over the frequency range of
the instrument. These models find wide use for system applications and are
adaptable for through-the-panel installations.
A smooth operating dial and drive mechanism provides accurate
control of attenuation free from any backlash or play. The engraved dial
is marked directly in 1 dB values from 0 to 40.0 dB. Calibration is made
at a single frequency in accordance with the table.
The instruments are designed, electrically and mechanically, for
precise operation over wide ranges of temperature and humidity. The
maximum attenuation range is achieved in less than one counterclockwise rotation
of the drive shaft. Calibration accuracy and mechanical dimensions are
shown in the tables. Alternate flanges and materials are available.
See flange section. Finish is instrument gray enamel.
