FY6900 DDS Dual Channel Arbitrary Waveform Generator

The FY6900 DDS Dual Channel Arbitrary Waveform Generator from meterk delivers precise, high-fidelity signal output using Direct Digital Synthesizer (DDS) technology. Designed for engineers, researchers, and labs, this dual-channel instrument generates stable, low-distortion waveforms across a wide range of applications—from routine testing to complex signal simulations. With two independent channels and advanced modulation and sweep capabilities, you can craft, analyze, and replay intricate signal patterns with confidence.

Key advantages include a 2.4-inch TFT color LCD showing real-time parameters and graphics for CH1 and CH2, and MagicPulse technology delivering ultra-low jitter (RMS < 200 ps). The 14-bit high-speed DAC, 300 MSa/s sample rate, and 5 Vpp output ensure high-resolution waveforms with minimal quantization error (less than 1 mV). The FY6900 supports up to 99 function or arbitrary waveforms, including 35 preset shapes and 64 user-defined files, with programmable depth of up to 8192 points for each waveform to preserve signal detail.

Beyond standard waveforms (Sine, Square, Pulse, Triangle/Ramp, CMOS, TTL, Exponential Rise/Fall, Noise, ECG, DC, and more), it offers comprehensive modulation options and advanced features such as AM, FM, PM, ASK, FSK, and PSK, as well as a versatile Sweep function to vary frequency, amplitude, offset, or duty cycle with Linear or Logarithmic sweep types. The built-in VCO lets you control frequency, amplitude, offset, and duty cycle from an external input, while Burst and Counter modes expand testing scenarios. Channel synchronization enables multi-channel, phase-controlled outputs up to 16 channels with 0.01° precision.

Benefits & Tips

• Create and reuse complex signal patterns by storing up to 64 arbitrary waveform data files and leveraging the 8192-point depth for high-detail reproductions.
• Simulate real-world conditions quickly by using the Sweep, Modulation (AM, FM, PM, ASK, FSK, PSK), and Burst features to stress-test devices and measure responses.
• Operate two synchronized channels with precise phase (0.01°) and independent duty-cycle control to compare signals or generate coordinated test sequences for multi-channel systems.
