Description

The GP1700 PAV frequency response analyzer is a versatile and powerful test and measurement instrument. Using 10uV - 100Vpk (600Vpk with supplied probes) isolated inputs with a powerful DSP based Discrete Fourier Transform (DFT) measurement, accurate phase sensitive and frequency selective measurements are possible. In particular the GP1700's gain, phase, power and LCRZ measurements offer good accuracy and noise rejection, necessary in most switching power supply power conversion, ultrasonic and EL backlight applications. Its unique ability to measure impedance parameters during actual live operating conditions, up to 600Vrms, can reveal hidden circuit properties - not possible with conventional LCR meters.

The main applications for the GP1700 include assessment of synchros, resolvers, LVDT, gain phase margins and stability in closed loop control systems, ultrasonic equipment, analysis of inductors, response of active/passive filters, piezo devices and amplifiers. Using its frequency sweep capability to create Bode Plots, impedance plots, Q factor, reactance and Resr plots. Particularly suited to situations where the measured signal is not referenced to ground or buried in noise and distortion.
