Wayne Kerr Frequency Response Analyser RA200. An electronic laboratory instrument designed to measure and display the frequency response of electrical and electronic circuits. The unit features a cathode-ray display with calibrated grid, rotary and push-button controls for sweep rate, frequency range and output level, and input and output connectors for test circuits. Used to analyse amplifiers, filters, transducers and communication equipment by plotting signal response across a range of frequencies.
Manufactured by Wayne Kerr, a British company known for precision electronic test equipment, the analyser formed part of laboratory and industrial testing environments including telecommunications, research facilities and engineering workshops. Late 1970s to 1980s, prior to widespread digital spectrum analysis systems.
