The Tektronix AWG7121B is a single-channel arbitrary waveform generator delivering 12 GSa/s sampling for high-fidelity signal creation across communications, aerospace, defense, and serial data testing. It generates complex waveforms with 100 fs edge timing resolution, supports up to 64 M-point record length, and operates in continuous, triggered, and gated modes. The instrument provides selectable 10-bit or 8-bit vertical resolution, output voltage from 50 mV to 2.0 Vp-p (normal mode), and direct RF generation to 9.6 GHz. Total jitter measures 20 ps p-p typical at 10⁻¹² BER with 35 ps rise/fall time. Real-time sequencing supports up to 16,000 steps with repeat, wait-for-trigger, jump, and go-to-N controls. The AWG7121B accommodates up to 32,000 waveforms, handles 6 Gb/s data rates for serial streams, and imports waveform vectors from MATLAB, MathCAD, and Excel.
