The ET3320C is a high-performance DDS-based signal generator delivering precise waveforms up to 20MHz with ultra-low distortion. Featuring two independent yet phase-synchronized channels, it supports 5 standard waveforms (sine, square, triangle, ramp, DC) and 32 built-in arbitrary waveforms, with 8K memory depth and 200MSa/s sampling rate for exceptional signal fidelity. Equipped with a 2.4-inch TFT LCD (320×240) and bilingual menus (English/Chinese), the ET3320C offers intuitive operation. Its 13-bit vertical resolution ensures accurate output, while 50 user-defined waveform slots enable custom signal creation. Advanced modulation capabilities include AM/FM/PM, ASK/FSK/PSK (internal/external), alongside linear/logarithmic sweep and burst modes for dynamic testing. Additional features include a 100MHz frequency counter, 32-bit hardware counter, and USB connectivity for PC control via included editing software. Ideal for R&D, education, and electronics testing, the ET3320C combines versatility, precision, and ease of use in a compact design.
