The Keysight 33120A is a 15 MHz Function/Arbitrary Waveform Generator that delivers precise signal generation for test, measurement, and development applications. Built on Direct Digital Synthesis (DDS) technology, it produces stable waveforms across a broad frequency range—from 100 µHz to 15 MHz—with selectable standard waveforms and custom arbitrary waveform capability. The instrument combines front-panel simplicity with full programmability via GPIB and RS-232, supporting both standalone operation and automated system integration.
