No other DDS generator offers this performance at this price. The output amplifier has a bandwidth approaching 100MHz ensuring that waveform quality is excellent right up to the frequency limits. Amplitude flatness is better than 0.2dB to 1MHz and 0.4db to 40MHz. Low noise design ensures minimum waveform aberrations and provides high waveform quality even at minimum output amplitude. High speed arbitrary waveforms In addition to it's eleven 'standard' waveforms, the TG4001can generate arbitrary waveforms of any length between 4 and 65,536 points at speeds of up to 100MS/s. Up to four arbitrary waveforms can be stored within the instrument. Waveform Manager Plus software for Windows is supplied for waveform creation and editing on a PC.

Alternatives products: All waveforms can be swept over their full frequency range at a rate variable between 1 millisecond and 15 minutes. 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 TG4001 provides nine memories for storing settings (plus one memory for automatically storing the settings at switch off). Because all parameters are controlled electronically, the memories store the complete set-up of the instrument. Waveform Manager Plus (supplied) provides all of the features needed for the creation, manipulation and management of arbitary waveforms within a single Windows-based program. If the TG4001 doesn't exactly meet your needs, TTi can offer other generators with a different range of features. Amplitude modulation (VCA) and suppressed carrier modulation (SCM) are available for all waveforms using the rear panel modulation input. A separate signal summing input is also provided, allowing waveforms from another signal source to be amplified and summed with the main output.

Waveform Sync provides square wave at the frequency of the main output. Burst Done produces a pulse coincident with the last cycle of a burst. Sweep Sync outputs a pulse at the start of each sweep to synchronise an oscilloscope or recorder. Sweep Marker provides an additional output pulse for use as a marker in sweep mode. Phase Lock Out can be used to phase lock two or more generators. Produces a positive edge at the 0o phase point. Trigger Out provides a replica of the trigger signal which can originate from the trigger input socket, the internal trigger/gate generator, the manual trigger key, or the bus interface. All waveforms are available as a triggered burst whereby each trigger edge will produce one burst of the carrier. Start and stop phase is fully variable. Both Triggered and Gated modes can be operated from the internal trigger generator, from an adjacent channel, an external source or a key press or remote bus command. The trigger generator is variable between 0.005 Hz and 100kHz, and the signal is available as a separate output if required. Tone switching & FSK The TG4001 can provide triggered switching between up to 16 frequencies of standard or arbitrary waveforms. Tone switching modes can be gated, triggered or FSK using any trigger source. Frequency Shift Keying provides phase coherent switching between two selected frequencies at a rate defined by the switching signal source. In tone switching mode the generator is set to switch between a number of different frequencies in response to a trigger signal. Ease of use The TG4001 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 for quasi-analogue control. Frequency or period entry The generator frequency can be set in terms of either frequency or period. Numeric entry can be floating point using whatever units the operator prefers, or can be done in exponent format. Flexible amplitude entry Amplitudes can be entered in terms of peak to peak voltage, RMS voltage or dBm. The output amplitude can be set in terms of either the voltage into a 50W or 600W termination, or in terms of the source EMF (for a high impedance load). Choice of interfaces The program supports RS232, USB and GPIB interfaces for download and upload. Upload from DSOs The program can read several file formats and supports waveform import via the clipboard allowing it to accept waveform files from most DSOs and digitisers. A full suite of tools Powerful mathematical functions are combined with on-screen drawing tools and clipboard functions to enable virtually any waveform to be created either from scratch, or from the editing of existing waveforms. Waveforms can be built in any number of sections using any combination of the following: Standard waveforms, mathematical expressions, drawn waveforms, uploaded waveforms, imported waveforms (using clipboard), existing stored waveforms. Waveforms can be viewed with variable zoom and printed with annotation. Waveform management tools include Projects and Libraries for professional organisation.
