A DDS generator at a non-DDS price The TG1010 breaks new ground by offering a DDS function generator at a similar price to that of a conventional generator of comparable functionality. It can generate a wide variety of waveforms between 0.1mHz and 10MHz with a resolution of 7 digits and an accuracy better than 10ppm. Direct digital synthesis for accuracy & stability Direct digital synthesis (DDS) 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. The DDS generator offers not only exceptional accuracy and stability but also high spectral purity, low phase noise and excellent frequency agility. A wide range of waveforms The TG1010 generates high quality sine, square and pulse waveforms over the full frequency range of 0.1mHz to 10MHz. Triangle waveforms, ramp waveforms and multi-level squarewaves can also be generated subject to some limitations in the maximum useable frequencies. Variable symmetry/duty-cycle is available for all waveforms. Arbitrary waveform capability Arbitrary waveforms can be loaded via the digital interfaces and then used in a similar way to the standard waveforms. Up to five arbitrary waveforms of 1024 10-bit words can be stored in non-volatile memory. The waveform clock is 27.48MHz maximum. This facility considerably expands the versatility of the TG1010 making it suitable for the generation of highly complex waveform patterns. In addition, the TG1010 offers numerous “complex” waveforms pre-defined in ROM. These include commonly used waveshapes such as sine x/x, decaying sinewave, exponential rise and fall etc. Locked generators The signals from the Clock In/Out socket and the Sync Out socket can be used to phase lock two or more generators. This can be used to generate multi-phase waveforms or locked waveforms of different frequencies. Fully programmable Addressable RS-232 standard, GPIB optional The TG1010 has an RS-232 interface as standard which can be used for remote control of all of the instrument functions or for the down-loading of arbitrary waveforms. As well as operating as a conventional RS-232 interface, it can also be used in addressable mode whereby up to 32 instruments can be linked to one PC serial port as part of a TTi “ARC” system. Alternatively, a GPIB interface conforming to IEEE-488.2 is available as an option.		Powerful modulation modes: Sweep All waveforms can be swept over their full frequency range at a rate variable between 10 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. Two sweep markers are provided which are adjustable whilst sweep is running. The markers can provide a visual indication of frequency points on a ‘scope or chart recorder. AM Amplitude Modulation is available for all waveforms and is variable in 1% steps up to 100%. An internal AM source is incorporated. Alternatively modulation can be controlled from an external generator. FSK Frequency Shift Keying provides phase coherent switching between two selected frequencies at a rate defined by the switching signal source. The rate can be set from dc to 50kHz internally, or dc to 1MHz externally. Trigger/Burst All waveforms are available as a triggered burst whereby each positive edge of the Trigger signal will produce one burst of the carrier, starting and stopping at the phase angle specified by the start-stop phase setting. The number of cycles in the burst can be set between 0.5 and 1023. Gated The Gated mode turns the output signal On when the gating signal is high and Off when it is low. Both Triggered and Gated modes can be operated from the internal Trigger Generator (0.005Hz to 50kHz) or from an external source (dc to 1MHz). Waveform hop The generator can be set up to ‘hop’ between a number of different waveform set-ups either at a pre-determined rate or in response to a manual or bus trigger. Up to 16 different hop waveforms can be defined in terms of frequency, amplitude, function, offset and duration, which is variable in 1ms steps up to 60 seconds. Noise generation The TG1010 can be set to simulate wide band random noise with adjustable amplitude and offset. Easy and convenient to use The TG1010 is 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. This system combines quick and easy numeric data entry with quasi-analogue adjustment when required.
