Adopt the Direct Digital Synthesizer (DDS) technology and provide stable, precise, pure and low distortion signals.Equipped with channel tracking function, when the tracking function is turned on, all parameters of both channels can be updated according to the user's configuration at the same time.No range limit: The full range of frequency is not divided into gear switches, program-controlled settings Desktop design with ABS plastic housing, AC 100 - 240V (AC) wide voltage supply; Two or more instruments can synchronize multiple instruments through the SYNC port.The phase adjustment range of the two channels is 0~359.99°, and the adjustment accuracy is 0.01° 2.4 inch TFT Color LCD with 320x240 resolution, displaying parameters and graphics of the two channels at the same time.Up to 98 sets of function/arbitrary waveforms can be output, including 34 sets of preset waveforms and 64 sets of user-defined waveforms. Preset waveforms include: sine wave, square wave (duty ratio adjustable), triangle wave.Burst Output Function The instrument uses 14-bit high-speed D/A converter chip (5Vpp output quantization error is less than 1mV), 250MSa/s sample rate, 14bits vertical resolution.Enable to store 64 arbitrary waveform data files, each one of waveform storage depth 8192 points * 14bits.High frequency accuracy: Frequency accuracy can reach 10-6 orders of magnitude.The duty cycle of both channels can be adjusted independently, with an accuracy of 0.01% Fully independent dual-channel output (equivalent to two independent signal sources), able to work synchronously, and the phase difference can be accurately adjusted;The frequency resolution is relatively high: the full-range frequency resolution is 1uHz (0.000001Hz).Amplitude resolution is higher: Amplitude resolution can be as low as 1mV (0.001V);With -10V~+10V DC bias function (<20MHz), resolution up to 1mV;
