More waves than you could shake a stick at from this sophisticated and versatile universal generator for standard or arbitrary waveforms
The TGA1241, new from TTi (Thurlby Thandar Instruments), is a sophisticated universal generator capable of recreating virtually any waveform.
The TGA1241 has a universal signal source architecture and provides the functionality of several different generators within a single instrument.
It operates as a standard function generator producing high quality sine, cosine, haversine and havercosine waveforms from 1mHz to 16MHz with square waves available up to 20MHz.
Triangle, ramp and sine x/x waveforms are also available.
Setting resolution is seven digits or 1mHz. Arbitrary waveforms may be defined with 12-bit vertical resolution and from four to 65,536 horizontal points.
The waveform replay clock is variable between 0.1Hz and 40MHz.
The total amount of non-volatile waveform store is 256k words.
Up to 100 waveforms may be stored with the length and name specified by the user.
Waveforms may be strung together to form a sequence of up to 16 steps.
Each waveform may have a user-defined repeat count from one to 32,768.
This allows highly complex waveforms to be created.
The TGA1241 can generate not just pulses but complex pulse trains.
A pattern of up to ten 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.
Where variable risetime pulses are required, the arbitrary facility can be used.
Modulation modes include wide-range phase-continuous sweep, AM, tone switching, and signal summing.
A built-in trigger generator provides gated and triggered burst modes.
All waveforms can be swept over their full frequency range at a variable rate.
Amplitude modulation and signal summing are available for all waveforms.
Extensive waveform editing features between defined start and end points are incorporated, including waveform insert, point edit, line draw, amplitude adjust and invert.
More comprehensive features are available using the Waveform Manager Plus arbitrary waveform creation software supplied.
This is a powerful Windows-based design tool that enables the user to create waveforms from mathematical expressions, from combinations of other waveforms, freehand drawing, or using a combination of all three techniques. DSO waveforms can also be directly imported.
The TGA1241 uses an 80-character backlit LCD display with soft keys.
All parameters can be entered directly from the numeric keypad or can be incremented and decremented using the rotary control.
An RS-232 and a GPIB interface are fitted as standard, and can be used for remote control of all of the instrument functions and for the downloading of arbitrary waveforms.
The TGA1241 costs œ1095 (plus VAT), including Waveform Manager Plus software.
