The 1644A is a bridge from General Radio. A bridge is useful for precise measurements, instrumentation, power conversion, and filtering in both linear and nonlinear applications. Pair bridges with other types of electronic test equipment to measure fixed and swept frequency return loss. Bridges check the performance of your system and its components, including amplifiers, couplers, filters, attenuators, terminations, and splitters.
Additional Features:
Seven fixed test voltages are available (10 to 1000 V)
Although any voltage between 10 and 1000 V may be obtained using an external resistor.
Resistance range of 10E+03 to 10E+15 ohms with ±1% accuracy to 10E+12 ohms (Delta R measurements to ±0.2%)
Utilizes self-checking internal standards
The General Radio 1644A, Megohm Bridge, that is ideally suited to measure a wide range of resistance from the insulation resistance of cables, to high-valued resistors, diodes, transistors, to voltage and temperature coefficients of resistance, to volume and surface resistivity of solids.
