TF2330 Marconi Wave Analyser
The TF 2330 Wave Analyser provides comprehensive measurement facilities for the analysis of the performance of devices operating within the audio and ultrasonic frequency spectrum. The amplitude of each individual frequency component of a complex signal may be determined in terms of absolute voltage or relative to a fundamental datum level in decibels or in percent.

Basically the instrument comprises a sensitive narrow band tuned voltmeter covering the range 3 p.V to 300 V. With a bandwidth of 7 c/ s it may be tuned to any frequency from 20 c/s to 50 kc/s; after initial tuning internal automatic frequency control may then be employed to lock it to the signal component to obviate continual retuning, thus ensuring accurate meter readings.

While a signal is being investigated a variable output voltage is available, having the same frequency as the signal component to which the Analyser is tuned. When the component is not harmonically connected to any other known component of the input signal, this output may be applied to an external counter for a more accurate determination of its frequency.

Another function of the instrument is to provide a convenient facility for determining frequency responses. A beat frequency oscillator, controlled by the voltmeter tuning and in step with it, provides a variable output voltage which, when set, remains constant over the whole frequency range. By applying this signal to the input of a circuit and monitoring the output with the tuned voltmeter section the response of the circuit can be rapidly ascertained.

TF 2330R is a rack mounting model which differs only in having a special case with flanges for fitting to a 19 inch rack.

An optional accessory's Tunable Rejection Filter TF 2334. This instrument has been designed primarily to extend the measuring range of wave analysers for the measurement of very low level harmonic and intermodulation components (but can also be used in conjunction with a valve voltmeter for approximate distortion factor and frequency measurements).
