Universal Bridge 4265A

The Hewlett-Packard Model 42654 Universal Bridge provides high precision measurements of L, C, or R and D or Q.  Components can be measured in the ranges of 0.1 pH to 1111 H in inductance, 0.1 pF to 1111 pF in capacitance, and 0.1 mn to 1.111 Mn in resistance with full four digit in-line display. The L and C measurements are performed over a wide range of loss with either series or parallel equivalent circuits selected by the FUNCTION switch. The basic measurement accuracy is 0.2% of reading for L, C and R. The measurement frequency range is 50 Hz to 10 kHz with an external oscillator, and 1 kHz with internal oscillator. A DC measurement for resistance also is available with external DC power supply and null detector. The front panel design provides appropriate space and convenient positioning of knobs for easy balancing. The handle is used as the tilt stand, and a front panel angles of 40 or 60 degrees may be chosen.
