    A new price point for a DDS generator

    The TG2000 breaks new ground by offering a high quality DDS function generator at a significantly lower price.  DDS (direct digital synthesis) is a technique for generating waveforms digitally using a phase accumulator, a look-up table and a DAC. The accuracy and stability of the resulting waveforms is related to that of the crystal master clock.  When correctly engineered, the DDS generator offers not only exceptional accuracy and stability but also high spectral purity, low phase noise and excellent frequency agility.

    Total digital control

    Unlike some other generators which only provide digital control of frequency, every function is digitally controlled enabling complete instrument set-ups to be stored, or full remote control to be implemented .

    Wide frequency & amplitude range

    The generators can generate waveforms between 0.001Hz and 10MHz or 20MHz with a resolution of six digits and a one year accuracy better than 10ppm.  Amplitude is variable between 5mV and 20V pk-pk from a source impedance of 50 Ohm or 600 Ohm. Waveform quality remains excellent over the full amplitude range.

    RS-232 & USB interfaces

    The TG2000 includes both an RS-232 interface and USB interface as standard. These interfaces can be used for remote control of all of the instrument functions and for storing instrument set-ups.

    Easy and convenient to use

    The generators are particularly easy to use. All of the main information is clearly displayed on a backlit LCD with 4 rows of 20 characters. Sub menus are used for the modulation modes and other complex functions.  All parameters can be entered directly from the numeric keypad. Alternatively most parameters can be incremented or decremented using the rotary encoder for quasi-analogue control.


    All waveforms can be swept over their full frequency range (0.1Hz minimum) at a rate variable between 20 milliseconds and 15 minutes. The sweep is fully phase continuous.  Sweep can be linear or logarithmic, single or continuous. Single sweeps can be triggered from the front panel, the trigger input, or the digital interfaces.   A sweep marker is provided that is adjustable whilst sweep is running. The markers can provide a visual indication of frequency points on a ‘scope or chart recorder.


    The Gated mode turns the output signal On when the gating signal is high and Off when it is low.  The gating source can be the front panel key, trigger input socket, or bus interface signal.


    External Amplitude Modulation is available for all waveforms via the VCA input.


    Frequency Shift Keying provides phase coherent switching between two selected frequencies at a rate defined by the switching signal source.  The switching source can be the front panel key, internal trigger generator, trigger input socket, or bus interface signal.

    Tone Switching

    The generator can be set to switch between a number of different frequencies in response to a trigger signal.  Up to 16 frequencies can be defined. The tone is output while the trigger signal is true, and stops (after completion of a full cycle) when the trigger signal is false. The next tone is output when the trigger signal goes true again.
