?The FY6800 Double Channel DDS Function Arbitrary Waveform Signal Generator Adopts the Direct Digital Synthesizer (DDS) technology and provide stable, precise, pure and low distortion signals.Desktop design with ABS plastic housing, AC 100 - 240V (AC) wide voltage supply; High reliability: Large-scale integrated circuit, surface mount technology, long service life; Two or more instruments can synchronize multiple instruments through the SYNC port. ? 2.4 inch TFT Color LCD with 320x240 resolution, displaying parameters and graphics of the two channels at the same time.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.Fully independent dual-channel output (equivalent to two independent signal sources), able to work synchronously.Burst Output Function: Manual Trigger, internal CH2 Trigger, and External Trigger. ?No range limit: program-controlled settings; With digital signal output function, it can realize any CMOS level with 0~10V amplitude;It can scan the four properties of the signal: frequency, amplitude, offset, and duty cycle.Two scanning modes: linear scan and logarithmic scan. Frequency accuracy can reach 10-6 orders of magnitude;The full-range frequency resolution is 1uHz (0.000001Hz);100M Frequency meter function:It can measure frequency, period, pulse width and duty cycle. ?Various modulation types:AM,FM,PM,ASK,FSK,PSK modulations.Counter Function:2 coupling measure modes including DC coupling and AC coupling.Amplitude resolution can be as low as 1mV (0.001V);With -10V~+10V DC bias function (<20MHz), resolution up to 1mV;The duty cycle of both channels can be adjusted independently, with an accuracy of 0.01%;The phase adjustment range of the two channels is 0~359.99°, and the accuracy is 0.01° ?Open communication protocol makes secondary development very simple;Output short-circuit protection: All signal outputs can work under load short-circuit conditions 60S or more;Equipped with channel tracking function.Up to 98 sets of function/arbitrary waveforms can be output, including 34 sets of preset waveforms and 64 sets of user-defined waveforms.Support VCO voltage control signal output function (such as voltage controlled oscillator).
