The AWG2021 Arbitrary Waveform Generator offers fast (250 MS/s) and deep memory (256 k). As with the entire 2000 Series family, the graphical user interface allows on-screen viewing of waveform editing and simplifies "what if" test scenarios by easily allowing the creation of composite signals. The unit provides one 5 V output 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.
