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, simplifying "what if" test scenarios by allowing the easy creation of composite signals.
The standard AWG2021 configuration provides one 5 V output or a second independent 5 V 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 conjunction 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 modulation 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 waveform transfer capability makes the AWG2021 the perfect complement to selected Tektronix oscilloscopes.

Operating Modes
Continuous - Output continuous at programmed waveshape, frequency, amplitude and offset.
Triggered - Output quiescent until triggered by an external, GPIB or manual trigger; then generates a sequence only one time.

Burst - Output quiescent until triggered by an external, GPIB or manual trigger; then generates "n" sequences or cycles.
Waveform Advance - Continuously generates the waveform in a predefined sequence; the next trigger advances to the next waveform in sequence.
