YERTAI ET3320C 20MHz DDS Dual-Channel Function Generator with USB

Description

Product Overview

The YERTAI ET3320C is engineered as a versatile, dual‑channel function generator that meets the demanding requirements of modern electronics development, research laboratories, and field service technicians. Operating with a Direct Digital Synthesis (DDS) architecture, the unit provides a clean, stable frequency output across a 20 MHz range, while delivering 13‑bit vertical resolution for fine amplitude control. The built‑in 100 MHz high‑precision frequency counter enables real‑time verification of generated signals, eliminating the need for separate measurement equipment. A 2.4‑inch TFT LCD with a 320 × 240 pixel matrix offers an intuitive graphical interface, allowing users to select from five standard waveforms—sine, square, triangle, ramp, and pulse—and up to 32 user‑defined arbitrary waveforms. The device stores up to 50 custom waveforms internally, and its USB communication port supports seamless integration with PC‑based waveform editing software, providing a flexible platform for complex signal generation tasks. Weighing only 600 g and measuring 9.5 × 9.3 × 4.6 inches, the ET3320C is portable enough for on‑site diagnostics while still delivering laboratory‑grade performance.

Usage

Designed for a broad spectrum of applications, the ET3320C excels in environments where precise signal generation and measurement are critical. In a research lab, engineers can employ the generator to synthesize test signals for filter characterization, amplifier linearity studies, and mixed‑signal verification. Its dual‑channel capability allows simultaneous generation of complementary signals, such as carrier and modulation waveforms, facilitating rapid prototyping of communication circuits. Field technicians benefit from the rugged yet lightweight design, using the unit to troubleshoot power electronics, motor drives, and sensor interfaces directly at the equipment site. The USB interface enables quick transfer of custom waveforms from a laptop, while the built‑in ASK, FSK, and PSK modulation functions support testing of digital communication protocols without additional hardware. Whether you are calibrating a spectrum analyzer, validating a microcontroller’s peripheral, or performing educational demonstrations, the ET3320C provides a reliable, user‑friendly solution.
