The Type 561-D Vacuum-Tube Bridge makes possible the measurement of the low frequency dynamic coefficients of vacuum tubes and transistors over very wide ranges of values, and under a wide variety of operating conditions. The circuits used are such that independent, direct-reading measurements of forward and reverse voltage-amplification factor, resistance, and transconductance can be made quickly and easily. Interelectrode and other stray capacitances are balanced out in such a manner t ...
