The AWG2021 offers 250 MS/s and 256 k

deep memory. As with the entire AWG2000

Series, the graphical user interface allows

on-screen viewing of waveform editing, sim-

plifying “what if” test scenarios by allowing

the easy creation of composite signals.

The standard AWG2021configuration pro-

vides one 5 V output or a second independ-

ent 5V output (Opt. 02) each with 12-Bit

vertical resolution. Frequency of channel 2

is also independently programmable.

Option 03 adds a 12-Bit wide differential

ECL digital port which can be used in con-

junction with the marker outputs for data

generation up to 14 Bits wide at up to

250 MHz. Or if you prefer, Option 04 provides

TTL digital levels with up to two 12-Bit,

100 MS/s ports for a total of 28 Bits wide.

The built-in frequency domain (FFT) editor

(Opt. 09) is a perfect addition for customers

performing proprietary or standard modula-

tion simulations, filter design or in physical

layer testing. Real-time waveform sequencing

extends the effective record length output

to over a billion points!

The AWG2021 easily simulates signals

where moderate point definition and long

records are required for simulating very

complex waveform conditions. Direct wave-

form transfer capability makes the AWG2021

the perfect complement to selected

Tektronix oscilloscopes.

Operating Modes

Continuous – Output continuous at programmed

until the sequence started is completed.

Burst – Output quiescent until triggered by an
external, GPIB or manual trigger; then generates
“n” sequences or cycles.

waveform in a predefined sequence; the next trig­ger advances to the next waveform in sequence.

Autostep – Generates the predefined waveform
once in the Autostep File; the next trigger advances
