The BK Precision model 4078 Dual Channel Arbitrary Waveform Generator uses direct digital synthesis to generate waveforms up to 400,000 points HAMEG HMF 2550 digital AWG under an oscilloscope displaying the generated waveform. An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms.
The number of digital channels defines the maximum width of any pattern generated - typically, 8-bit, 16-bit, or 32-bit pattern generator. A 16-bit pattern generator is able to generate arbitrary digital samples on any number of bits from 1 to 16. The maximum rate defines the minimum time interval between 2 successive patterns.
One way to reduce the truncation in the address lookup is to have several smaller lookup tables in parallel and use the upper bits to index into the tables and the lower bits to weigh them for linear or quadratic interpolation. Ie use a 24-bit phase accumulator to look up into two 16-bit LUTS. Address into the truncated 16 MSBs, and that plus 1.
An arbitrary waveform generator (AWG or ARB) is a sophisticated signal generator that generates arbitrary waveforms within published limits of frequency range, accuracy, and output level. Unlike a function generator that produces a small set of specific waveforms, an AWG allows the user to specify a source waveform in a variety of different ways.
Direct digital synthesis (DDS) is a method employed by frequency synthesizers used for creating arbitrary waveforms from a single, fixed-frequency reference clock. DDS is used in applications such as signal generation , local oscillators in communication systems, function generators , mixers, modulators , [ 1 ] sound synthesizers and as part of ...
Arbitrary waveform generators may have distortion less than -55 dB below 50 kHz and less than -40 dB above 50 kHz. Some function generators can be phase locked to an external signal source, which may be a frequency reference or another function generator. Amplitude modulation (AM), frequency modulation (FM), or phase modulation (PM) may be ...
Keysight Technologies, Inc. is an American company that manufactures electronics test and measurement equipment and software. The name is a blend of key and insight. [2] [4] The company was formed as a spin-off of Agilent Technologies, which inherited and rebranded the test and measurement product lines developed and produced from the late 1960s to the turn of the millennium by Hewlett-Packard ...
Amplitude-shift keying (ASK) is a form of amplitude modulation that represents digital data as variations in the amplitude of a carrier wave. [1] In an ASK system, a symbol, representing one or more bits, is sent by transmitting a fixed-amplitude carrier wave at a fixed frequency for a specific time duration.
