THURLBY THANDAR INSTRUMENTS TGA1200 Series Single and Multi-channel Universal ARB Generators 1, 2 or 4 independent or inter-linked channels 40MS/s or 100MS/s, up to 1M words per channel Function generator and pulse generator capabilities
TGA1200 series universal ARB waveform generators Universal generators A true arbitrary generator Function generator The TGA1200 series combine a true variable clock arbitrary generator with a high performance DDS function generator and pulse generator in a single instrument. The TGA1200 series are highly sophisticated 12-bit arbitrary generators capable of recreating virtually any waveform. Each channel can operate as a full DDS function generator.
40MS/s or 100MS/s - one, two or four channels Waveform creation and editing Waveform creation and editing features are incorporated within the instrument. These include waveform insert, point edit, line draw, amplitude adjust and invert. A wide range of standard waveforms is available for insertion within an arbitrary waveform. Sections of existing arbitrary waveforms can also be inserted.
Waveform Manager Plus - included with all TGA1200 series generators Advanced waveform creation, editing and management software WAVEFORM MATHEMATICS The Waveforms Maths function allows waveforms to be combined and manipulated independently of the expression editor. Waveforms can be scaled, offset, added, subtracted or multiplied using dialogue boxes. Note: Waveforms can also be combined and manipulated within the expression editor giving access to the full range of mathematical functions.
Technical Specifications Variable-clock ARB architecture Direct replay for jitter-free waveforms All TGA1200 series units generate arbitrary waveforms using a variable clock architecture rather than DDS. This ensures that every point in the waveform is replayed exactly as it was defined, the rate of replay being set by the clock frequency. By contrast, a DDS arbitrary generator uses a fixed clock frequency and varies the replay rate by duplicating or omitting waveform points.
