For ultrasonic components measuring instrument, the most important is the admittance chart, logarithmic graph of the two graphics (the two graphics is the main method of qualified qualified), and more than a dozen parameters: resonance frequency Fs, the maximum conductance Gmax, bandwidth F2-F1, anti-resonance frequency Fp, quality factor Qm, free capacitance CT, dynamic resistance R1, dynamic inductance L1, dynamic capacitance C1, static capacitance C0, effective electromechanical coupling coefficient Keff.
The Measuring instrument which can easily replac much more complex and more complicated, also many times more expensive instruments from Agilent/HP, as for instance: HP Impedance Gain-Phase Analyzer 4294A, Agilent E5100A, Network Analyzer, HP 3563A,Control System Analyzer etc. It is also very easy to use HS520A (by engineers or ordinary production workers).
HS520A is based on the HS70A and HS80A, a new generation of ultrasonic components analyzer;
