BRAND: GENERAL RADIOMODEL: 1650-A SERIAL NUMBER: 8474 CONDITION: THIS IS IN VERY GOOD CONDITION. LOOK AT THE PICTURES OF THE FACE. IT HAS BEEN PROTECTED BY THE HANDLED CASE. CASE HAS A FEW MARKS ON IT BUT OTHERWISE IN EXCELLENT CONDITION. MADE IN: U.S.A. SPECS: RANGES OF MEASUREMENT - Frequency: from 20Hz to 20kHz with internal 1kHz and DC. Capacitance: 1pF to 1100series or parallel 7 ranges Inductance: 1to 1100 H series or parallel 7 ranges Resistance: ac or dc 1 mOhm to 11 MOhm 8 ranges Dissipation Factor: D at 1 KHz 0.001 to 1 of series C 0.1 to 50 of parallel C The 1650-A Impedance Bridge is a versatile and compact instrument capable of accurate measurements of resistance, capacitance, inductance, dissipation and quality factor over a very wide range: 1 milliohm to 11 megaohm for resistance, 1 picofarad to 1100 microfard for capacitance and 1 microhenry to 1100 Henry for inductance. Accuracy better than 1% was given for R, C and L. The 1650-A uses custom made precision components for the arms of the bridge: the CRL rheostat used a mechanical justifying mechanism with eight linearizing cams; a silvered mica, high precision capacitor is used as standard capacitor. The Orthonull device, with non reciprocal ganging of CRL and D dials, was available for easy of balance convergence in cases of low Q or high D. Virtually any impedance measurement could be done with this instrument ITEM CAME FROM A LAB ENVIRONMENT AND IS UP TO SPECS
