Stanford Research DS345 Function and Arbitrary Waveform Generator, 30 MHz

RENT STANFORD RESEARCH SYSTEMS DS345 Function and Arbitrary Waveform Generator

Experience unparalleled performance with the Stanford Research Systems (SRS) DS345 Function and Arbitrary Waveform Generator, a versatile 30 MHz instrument that leverages an innovative Direct Digital Synthesis (DDS) architecture. This sophisticated generator excels in creating a variety of standard waveforms with remarkably precise frequency resolution of 1 µHz. You can generate sine and square waves up to 30.2 MHz, alongside triangle and ramp waveforms reaching up to 100 kHz. Additionally, the DS345 features a wideband white noise source (up to 10 MHz) and supports extensive modulation options—including AM, FM, burst, PM, and frequency sweeps.
