Precision digital frequency response analyzer included
The Alpha analyzer includes a broadband precision digital frequency response analyzer (FRA).
The FRA can be used without gain phase mode for broadband phase sensitive ac voltage measurements, too. The frequency range is 3 µHz up to 40 MHz (depending on the analyzer model).
Two voltage input channels for gain phase measurements with 0.001° phase - and 10-5 in amplitude resolution are provided.
Each channel measures the amplitude of the harmonic base wave (or higher harmonics) contained in the applied signal with respect to the generator frequency.
In addition, the phase angle between either the base waves or higher harmonics of each channel is measured with respect to the other channel.
