50MHz function generator hits new price point

The new TG5011 from TTi is a combined function/arbitrary/pulse generator with a frequency range covering 1µHz to 50MHz. At under £900 or €1100 the generator achieves a new price point below that of competitor products offering only 20MHz or 25MHz bandwidth.

The generator offers high purity sine waves with low harmonic distortion and low phase noise over the full frequency range. Square waves have a rise time of below 8ns and low overshoot giving good wave-shape right up to 50MHz.

The frequency of these waveforms can be set with up to 14 digits and is based on a TCXO timebase oscillator with a stability of 1ppm. The high resolution of the DDS system means that very low frequencies can be set. For example, a frequency of 1mHz can be set with a resolution of 0.1% and a stability of 1ppm.

The TG5011 incorporates a pulse generator mode which provides wide range pulse width and delay independent of period. Pulse period can be set between 2000 seconds and 80ns (0.5mHz to 12.5MHz) and the duty cycle can be as low as one in two billion. Rise and fall times (edge speeds) are also independently variable over a wide range.

Arbitrary waveforms of up to 128k words can be generated at 14 bits vertical resolution and a sampling speed of 125MS/s. A front mounted USB port enables external Flash memory storage of up to 1000 waveforms. This memory stick also provides a quick and convenient method for transferring waveform files to and from a PC.

Commonly used complex waveforms are provided including sin(x)/x, exponential rise and fall, logarithmic rise and fall, gaussian, lorentz, haversine and cardiac waveforms. The generator comes with Waveform Manager Plus for Windows enabling complex waveforms to be created using a PC.

The TG5011 offers a comprehensive set of digital modulations including AM, FM, PM, PWM and FSK. The modulation source can be any standard or arbitrary waveform, or any external signal applied to the modulation input.

A wide band noise generator creates gaussian white noise with a high crest factor and a bandwidth of 20MHz. Noise can be added to any waveform or can be used as a modulating source.

USB and LAN interfaces are provided as standard, the latter conforming with LXI class C (Lan eXtensions for Instrumentation). A GPIB interface is available as an option. All functions of the generator can be controlled from the digital interfaces, and arbitrary waveform data can be transferred via them.

The TG5011 is housed in a highly compact casing with protective buffers and a multi-position stand. With the buffers removed it is half-rack 2U for rack mounted applications. Despite its small size it incorporates a 3.6” (90mm) diagonal LCD panel that provides a large amount of text and graphical information simultaneously and offers context sensitive soft key control..
