(EQP) BOON250A
Boonton Radio Co. RX Meter, Type 250A impedance meter. 0.5 Mc - 250 Mc. 19" x 12" x 10" high. Includes manual. Never used. Brand new in the box!! The RX Meter, Type 250-A is a wide frequency range Impedance Meter designed to permit accurate individual determination of the equivalent parallel resistance and parallel reactance of two terminal networks and components. The instrument is completely self-contained and consists, fundamentally, of a refined Schering bridge circuit, together with its associated oscillator, detector, amplifier, null detector and power supply. Bridge balance is obtained by means of two calibrated dials which indicate, respectively, parallel resistance and parallel capacitance of the unknown. |
