Three models meeting a variety of needs
The TG315 includes dual digital display of frequency and amplitude, along with the basic generator functions of sine, square & triangle waveforms, variable DC offset, variable symmetry and an external sweep input. It also offers internal or external amplitude modulation.
Exceptional waveform quality
The TG300 series provides very high waveform quality under all conditions. That means low sinewave distortion, low aberation triangle waves and fast-edged square waves with low overshoot. Unlike many competitive products good waveform quality is maintained throughout the frequency range, and at low output levels. All models have bi-directional variable symmetry at constant frequency from 1:9 to 9:1.
Wide range level control
The main output has a maximum emf of 20V pk-pk from a 50 Ohm or 600 Ohm source. An amplitude vernier with a range of 40dB is combined with a -20dB switched attenuator to provide levels down to 20mV pk-pk. Variable DC offset of +/-10V is available via a centre detent control. An auxiliary output provides a fixed 0V to +5V level suitable for driving both TTL and CMOS loads.
Digital display for precision and convenience
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.
