The TG4001, new from TTi, is a low cost DDS function generator with arbitrary waveform capability that can generate high purity sine waves up to 40MHz and square waves up to 50MHz, double the frequency of other functions generators within a similar price bracket.

In addition to sine and square waves, it can generate cosine, haversine, havercosine, pulse, triangle, ramp and sine(x)/x waveforms. Setting resolution is 10 digits or 1mHz.
The TG4001 can generate not just pulses but complex pulse trains. A pattern of up to 10 pulses can be quickly defined with each pulse having its own amplitude, width and delay. The whole pulse train pattern can then be replayed at a user defined repetition rate.

As an arbitrary generator, it can produce waveforms of up to 65,536 (64K) words at sample rates of up to 100MS/s. Waveform Manager Plus software for Windows is supplied for creation and editing of waveforms on a PC. Waveforms are downloaded to the generator using RS232 or USB interfaces.

A full voltage output signal of 5mV to 20V pk-pk EMF from 50 Ohms is available over the full frequency range of the generator. Amplitude flatness for sinusoids is +/-0.2dB to 1MHz and +/-0.4dB to 40MHz. Pulse rise and fall times are less than 8ns.

Modulation modes include wide-range phase-continuous sweep, AM, tone switching, and signal summing. A built-in trigger generator provides gated & triggered burst modes. All waveforms can be swept over their full frequency range at a variable rate.

The TG4001 includes both RS232 and USB interfaces as standard. These give full control of every instrument function as well as providing arbitrary waveform download capability. A GPIB (IEEE-488) interface is available as an option.

The generator is housed in a half rack 3U case suitable for bench top or system use. A rack mount kit is available.

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
