Frequency Response Analyser

The Frequency Response Analyser enables you to measure the frequency response of a system in both magnitude and phase by using a swept sine output. They are commonly used to measure the transfer functions of electrical, mechanical, or optical systems.

Below is the Frequency Response Analyser’s user interface showcasing some of the key features explained below:

 

Key Features of the Frequency Response Analyser:

Stimulate the Device under Test

Select your required number of points per sweep and configure the settling and averaging times to balance the total sweep duration and signal-to-noise ratio. Then, quickly and easily measure the frequency response of a device from mHz to MHz, with a linear or logarithmic swept sine output.

 

Maths Channel

Add, subtract, multiply, or divide the input signals and view the result separately on the bode plot.

 

Cursors

Magnitude and phase cursors can be added to the interactive bode plot to monitor the phase, amplitude or frequency of the signals. The interactive bode plot allows you to view live results or pause the display for in-depth analysis.

 

Applications:

  • Impedance measurement
  • Biochemical impedance analysis
  • Electrochemical impedance analysis
  • Capacitance/inductance measurement
  • Stability analysis
  • Power supply analysis
  • EMI filter characterisation
