Features a 2.4 inch TFT Color LCD (320×240 resolution) displaying parameters and graphics for two channels simultaneously. Equipped with a 14-bit high-speed D/A converter (5Vpp output quantization error < 1mV), 250MSa/s sample rate, and 14-bit vertical resolution. Outputs up to 97 functions/arbitrary waveforms including 33 preset and 64 user-defined waveforms. Various modulation types: AM, FM, PM, ASK, FSK, PSK. Sweep Function: Sweeps frequency, amplitude, offsets, and duty cycle with linear and logarithm sweep types. Includes a 100M frequency meter function for measuring frequency, period, pulse width, and duty cycle. Standard dual full functional channels equivalent to two independent generators. Supports multi-channel output with options for up to 16-channel synchronous output. Precise phase adjustment between channels with 0.01° accuracy. Amplitude range of 0~24Vpp with a minimum resolution of 1 mV. Stores 20 user-set parameter sets for quick access. Comprehensive PC software for waveform editing, included with user CD. Technical Specifications Frequency Ranges: Sine (0~60MHz), Square (0~25MHz), Ramp/Triangle (0~10MHz), Pulse (0~10MHz), TTL/CMOS (0~10MHz), Arbitrary Waveform (0~10MHz). Resolution: 1μHz, ensuring high-frequency accuracy. Accuracy: ±20ppm, with stability ±1ppm/3 hours. Waveforms: Supports Sine, Square, Triangle, Sawtooth, and many more.
