Tektronix AWG Arbitrary
Waveform Generators give 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 digital to
analog convertor with sophisti-
cated triggering and mode
settings, plus up to 4 megabytes
of internal 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 wave-
forms, or define your own from
scratch. Using their powerful
editing tools, you can edit the
waveform right on the screen,
then clock it out at rates up to
1 GS/s.
For computer-controlled produc-
tion test applications demanding
high throughput, the AWG 2021
is available in VXI format as the
VX4792. This uncompromised
signal source delivers the same
bandwidth and accuracy as the
AWG 2021, and its waveform
record formats are identical to
those of the benchtop unit. As
such, the VX4792 allows easy
movement of waveforms and
instructions from the design lab
to the production line.
Where the utmost signal purity
is required, the AFG 2020
Arbitrary Function Generator
offers direct digital synthesized
waveforms with exceptionally
low distortion and high
frequency agility.
