Superior Performance at an Affordable Price
Most electronic devices, circuits, and systems are designed to handle some
form o f signal. These signals can be simple like an audio frequency or
clock signal or more complex like a serial data stream or the outpu t of an
airbag sensor d
uring a crash. With 20 MHz bandwidth, 14-bit resolution,
and 250 MS/s sample rate, the AF G 2021 Arbitrary Function Generator can
create both simple and complex signals at an entry-level price. With 12
standard waveforms, modulation capability, and a built-in noise generator
you can quickly create the signal you need to thoroughly exercise your
designs.
Intuitive User Interface
The innovati
ve ease-of-use features first seen o n the AFG3000 Series
arbitrary/function generators are the building blocks for the AFG2021,
providing quick access to setup and operational features. Experienced
AFG3000 users will find it especially easy to set up the new AFG2021. A
3.5 inch color T FT screen shows relevant parameters in both graphic and
text formats, so you can have full confidence in you r sett ings and focus on
the task at ha
nd. The front-panel sho rtcut b uttons and rotary knob provide
quick access to the most frequently used functions and settings.
Frequency
range from 1 μHz to 20 MHz, supports a wide range of amplifier and filter
testing ap
plications.
Excellent Frequency Agility
Traditional function generators created their output sig nals using ana log
oscillators and signal conditioning. The Tektronix AFG2021 relies on
Direct Digital Synthesis (DDS) techniques. DDS technology synthesizes
waveforms by using a single clock frequency to generate any frequency
within the instrument’s range. DDS architecture provides exceptional
frequenc
y agility, making it possible to program fast frequency a nd phase
changes, which is useful for testing radio and satellite system compone nts,
amplifiers, and filters.
