The TG1304 is a classic analogue function generator with all the versatility
that this implies including the generation of complex waveshapes right up to
the maximum generator frequency of 13MHz.Unlike other analogue generators,
however, it harnesses the power of a digital control system to provide an
unrivalled range of features.Frequency stabilisation
The TG1304 uses digital "measure and correct" techniques to stabilise the
main generator frequency to an accuracy of up to 0.01%. That provides not
only precision setting but also negligible drift with time. Complex waveform
generation In addition to the normal sine, square and triangle waveforms the
TG1304 can generate uni-polar pulse waveforms and DC levels.Variable
symmetry, variable start/stop phase and variable frequency trigger gating
also enable complex waveshapes such as haversines, variable transition time
pulses and sine-edged pulses to be obtained.
