Function generator


All the TG300 series generators incorporate a large dual-section digital display. Unlike competitive products the display provides a readout not just of frequency, but of amplitude or offset simultaneously.Auto-ranging reciprocal measurement gives 4-digit resolution with rapid update right down to Hz levels, below this an alternative technique is used to retain fast display update a sub-hertz frequencies.The output level display can be selected to show any of three values: volts pk-pk, volts rms, or dc offset.
The TG330 has all the features of the TG320 plus an internal sweep generator with linear or log sweep, variable sweep rate and a sweep output socket.It also offers internal or external amplitude modulation.
The TG320 and TG330 have an external counter mode which utilises the full width of the display to provide up to seven digits of resolution.The frequency range is from 5Hz up to 120MHz in two ranges, and the input sensitivity is better than 50mV rms.
The TG330 provides further versatility by adding AM facilities. The modulation can be external or internal (via a 400Hz internal generator) with modulation levels fully variable between 0% and 100%.
