Operating Impedance Bridge
This unit provides Iow distortion signals from 10 Hz to 100 kHz. An RC audio Circuit is followed by an amplifier with extremely Iow distortion characteristics. It is ideał for testing broadcast station response, high fidelity equipment, filter characteristics, and any equipment requiring a signal of a known frequency.

OIB-1 Operating Impedance Bridge
Delta CPB-1/1A Common Point Impedance Bridge
These two bridges are similar in operation to the OIB-1 model, but are designed for permanent installation in the phasing equipment at the antenna common point. The
CPB-1 will handle common point powers up to 5 kW with _
100% amplitudę modulation on a continuous basis. The
CPB-1 A is designed for transmitter powers up to 50 kW. B & K 210 Oscillator B & K 410 Distortion Meter
