• Annotazioni

• Purpose: The General Radio R-F Bridge 1606-A is a null instrument especially useful for accurate measurement of antennas, r-f components and other circuits having relatively low impedances.

  The frequency range of the bridge is from 400 kc to 60 Mc. Measurements can be made with reduced accuracy at frequencies somewhat above and below the normal limits. The low frequency limit is determined mainly by sensitivity considerations, and satisfactory measurements usually can be made at frequencies as low at 100 kc.

  The complete measurement setup usually consists of the Type 1606-A R-F Bridge, a well-shielded radio-frequency oscillator (eg. GR Type 1211-C Unit Oscillator), and a well-shielded radio receiver, which serves as a detector.

  The receiver should have a sensitivity control, a beat frequency oscillator, a switch to cut out the AVC circuit, and coverage of the frequency band 400 kc to 60 Mc, or any desired portion thereof. Conventional communication-type receivers usually are satisfactory.

  The bridge is mounted in an aluminum cabinet. Since capacitance between the bridge components and the inside walls of the cabinet comprises one arm of the bridge, the instrument cannot be used outside of the cabinet. For rough usage in field applications, a separate luggage type carrying case is available as an accessory.
