Phasemeter

Phasemeter is used for measuring the phase difference of two signals coming to the input channels of FFT spectrum analyzers. The upper line of the indicator displays the current phase difference value in degrees, the lower line – phase difference value in radians. It is possible to change the averaging of the displayed value (0.1 or 1 s) and to select necessary FFT spectrum analyzer channels.

Input data for Phasemeter includes digital data of the ZETLAB server channel.

Phasemeter is included into the following software packages:

• ZETLAB BASE – ADC/DAC module software;
• ZETLAB ANALIZ – FFT Spectrum Analyzers software;
• ZETLAB VIBRO – shaker control systems software;
• ZETLAB TENZO – strain-gauge station software;
• ZETLAB SEISMO – seismic station software;
• ZETLAB SENSOR – digital ZETSENSOR sensor software.

Phasemeter refers to the Measurement software group.
