ANTENNA NOISE BRIDGE - WITH NOISE RECEIVER

Integration of an RF Noise Source, Impedance Bridge, and Noise Receiver into one package

Noise sources and noise bridges have been around for a long time. Traditional methods would have us use these with our ham station receiver to measure the noise impedance at a specific frequency. Problem with this configuration is that the noise source may not be adequate at some frequencies, the receiver may not have adequate sensitivity on some bands, and connecting all the component parts together into a working system is time consuming and error prone.

This project is an effort to design and construct an integrated HF noise source, noise impedance bridge, and 1.7 to 56 MHz noise receiver into one easy to use package.

OBJECTIVES

• 1.6 to 56 MHz Coverage
• 0 to 1000 ohms range
• Digital frequency readout

Battery power portability is not a primary objective, although some care will be taken to keep power requirements within reason.

Nothing really new here, except that the 1.7 to 56 MHz band-switched direct-conversion receiver will be part of the test instrument itself.
