Frequency Response Analysers

Information from Newtons4th Ltd

Frequency response analysers (also known as gain/phase analysers or transfer function analysers) measure the relative gain and phase difference between two points in a circuit.

Frequency response analysers are particularly important in determining the loop stability of any closed loop feedback system (eg. amplifiers, power suppliers, control systems) - see our application note "Testing loop stability with QuanteQ or Veqtor". The results are usually presented in the form of Bode plots. They also have application in filter testing, electrochemistry, accoustics, R&D, and production testing.

Our Products

Netwons4th Ltd offer two frequency response analysers: the QuanteQ and Veqtor.

QuanteQ and Veqtor both offer a frequency range of 100µHz to 2.4MHz and will automatically sweep the frequency to generate Bode plots. The graphs are visible on the graphic displays, or may be printed out, or read into a computer over RS232. QuanteQ has high voltage capability to 500V peak cat II; Veqtor has input ranges from 1mV to 10V and a phase accuracy of better than 0.1°: at 100kHz and better than 1°: at 1MHz.

Both frequency response analysers offer other measurement capability as well as frequency response.
