ZYP - AN AUTOMATIC IMPEDANCE AND ADMITTANCE PLOTTER,
Abstract
ZYP will measure and record as a function of frequency complex impedances in the range 0 - 100 kilohms, complex admittances in the range 0 - 10 millimhos, and complex transfer functions. A two-phase oscillator supplies reference and quadrature switching signals between 30 and 30 000 c/s to a two-channel synchronous detector. Complex ratios are measured by holding the donominator signal constant and by delivering the numerator signal, which is then proportional to the complex ratio, to each channel of the synchronous detector. The two filtered dc output voltages of the detector deflect meters or an x-y recorder in proportion to the real and imaginary parts of the unknown ratio. (Author)
