For example, assuming a station at 1000 kHz and a measured reactance range of +/- 300 ohms, we would set the dial for 300 ohms, and then with the bridge grounded, adjust the initial balance knobs for ...

Some 30 years ago, my complement of RF test equipment consisted of a General Radio 1606B impedance bridge (GR bridge), a Potomac SD31 synthesizer-detector and a Delta OIB-1 operating impedance bridge.

In practice, LCR meters often replace the op amp with a zero phase detector and a modulator. This scheme lets autobalancing bridges work to about 100 MHz. MEASUREMENTS IN SOFTWARE ...

The model has been validated by performing: 1:1 and 0.1:1 impedance comparisons by means of two different typologies of calculable resistance standards. For the measurements, we relied on the accuracy ...
