TG5011 Aim-TTi Function/Arbitrary/Pulse Generator

The Aim-TTi TGxx11 Series Function/Arbitrary/Pulse Generators represent the state-of-the-art in DDS based function generators.

The 50MHz TG5011 significantly outperforms other generators in its price range, not just because of its frequency range, but because of its all round performance and features.

The TG2511 incorporates a similar feature set and represents exceptional value for those with lower frequency requirements.

The frequency of these waveforms can be set with up to 14 digits or one micro hertz of resolution. The DDS based frequency generation system uses a TCXO timebase oscillator with a stability of 1ppm.

The TG5011 and TG2511 generate high purity sine waves with low harmonic distortion and low phase noise. Square waves have a rise time of below 8ns (13ns on TG2511) and low overshoot. Variable symmetry can be used up to 25MHz.

High quality triangle and variable symmetry ramp waveforms can be achieved up to 500kHz (TG5011) or 250kHz (TG2511). These waveforms can also be achieved at higher frequencies via the arbitrary function but without symmetry adjustment and with reduced waveform quality as the frequency increases.

The high resolution of the DDS system means that very low frequencies can be set. For example, a frequency of around 1mHz could be set with a resolution of 0.1% and a stability of 1ppm.

Both models incorporate a pulse generator mode which provides wide range pulse width and delay independent of period. Rise and fall times (edge speeds) are also fully variable.

On the TG5011, the pulse period can be set between 80ns and 2000 secs. (0.5mHz to 12.5MHz) with a resolution of 14 digits or 1 µHz. On the TG2511, the minimum pulse period is 160ns (6.25MHz).

Pulse width and pulse delay can be independently set to a resolution of 10ns. Minimum pulse width is 20ns and duty cycles can be as low as one in two billion.

The generators offer very fast edge speeds of better than 8ns on the TG5011 or 13ns on the TG2511, but the edges can be slowed down to simulate slower pulses. Rise and fall times are independently variable in the range 5ns to 40us (10ns to 40us on the TG2511), or can be linked so that both edge speeds are the same.

As with all other waveforms, pulses can be triggered from an external trigger input (or manual trigger, the internal trigger generator or a Bus command). Burst mode creates a burst of between one and a million pulses in response to each active edge of the trigger. Gated cause pulses to be generated only when the gate signal is true. The gate source can be external or internal exactly as the trigger signal.
