Addendum -- Region ShiftSection 8 of this document describes a method for simulating jitter by convolving the data pattern with a second, slightly modified version of itself. This technique applies to the existing AWG 2000 Series products: AWG 2005, AWG 2021, and AWG 2041. Just before press time, Tektronix announced a new feature, known as "Region Shift," for AWG 2000 Series instruments. The first product to incorporate the feature is the AWG 2021. Region Shift allows the user to automatically modify a waveform's placement in time. The technique applies a minute amplitude shift to each point in a selected waveform region, with the net effect of making each point appear earlier or later in time relative to the unmodified pulses surrounding it. Using Region Shift, the AWG 2021 can produce jitter excursions as small as 4 ps. |

AWG 2000 Series Arbitrary Waveform GeneratorsTektronix AWG Arbitrary Waveform Generators give you the most extensive capabilities for editing waveforms, with 8 or 12 bits of vertical resolution and waveform frequencies to 500 MHz. AWGs contain a high speed, high resolution DAC with sophisticated triggering and mode settings, plus up to 4 megabytes of internal waveform memory in which to create and edit waveforms.
You can import a waveform from a scope or disk, select one of the AWG's standard waveforms, or define your own from scratch. Using powerful built-in editing tools, you can edit the waveform right on the screen, then clock it out at rates up to 1 GS/s.
TDS 744A Digitizing Oscilloscope![]()
The TDS 744A represents the next generation of digitizing scope performance. This versatile general-purpose instrument introduces Tek's new InstavuTM acquisition feature and sets a benchmark in waveform capture rate for DSOs. The TDS 744A can display more than 400,000 acquisitions per second--a rate 2,500 times faster than the most advanced DSOs available. Other TDS 744A features include advanced triggering, graphical user interface, high-speed signal processing, complementary probing, and sophisticated documentation capability. With its long record length and high bandwidth, the TDS 744A is an ideal complement to the 2000 Series AWGs for disk drive testing. Its feature set is also suited to applications ranging from digital system development to manufacturing test.
