Upgraded 15MHz DDS Signal Generator Dual-Channel vs Riiai 4-20mA / 0-24V Current Signal Generator
Overall winner: Upgraded 15MHz DDS Signal Generator Dual-Channel
Key Differences
Seesii FG-615 (A) targets lab bench use with dual-channel DDS, 200 MSa/s sampling and storage for 99 states and 60 custom waveforms, making it better for arbitrary-waveform and precision output. Riiai (B) focuses on 4-20mA and 0-24V current/voltage signaling with multiple modes and real-time curve display for PLC and loop testing. Choose A for high-speed, dual-channel waveform generation; choose B for process-signal and PLC testing where calibrated current/voltage output and on-screen curves matter
