The Agilent 33220A is a 20 MHz DDS function/arbitrary waveform generator with 14‑bit, 50 MSa/s AWG, 10 mVpp–10 Vpp output range, built‑in modulation and sweep modes, and standard USB/GPIB/LAN remote control; this unit powers on and functions but has a faulty front‑panel display which does not affect RF output or remote control operation. 

Technical Summary

The 33220A is a direct‑digital‑synthesis (DDS) function/arbitrary waveform generator intended for bench and production use. It produces clean sine and square waves up to 20 MHz, pulses up to 5 MHz, and linear ramps up to 200 kHz, with arbitrary waveform capability at 14‑bit resolution and 50 MSa/s sample rate (64k points). The instrument supports internal AM, FM, PM, FSK, PWM, burst, and sweep modes and stores up to four user waveforms in nonvolatile memory. 

Key Specifications

• Maximum frequency: 20 MHz for sine/square. 
• Arbitrary waveform: 14‑bit, 50 MSa/s, 64k points. 
• Amplitude range: 10 mVpp to 10 Vpp into high impedance; direct numeric entry in Vpp, Vrms, dBm supported.
