Features: Adopt the Direct Digital Synthesizer(DDS) technology and provide stable, precise, pure and low distortion signals. 2.4 inch TFT color LCD with 320*240 resolution, simultaneously display parameters and graphics of CH1 and CH2. Use 14-bit high-speed D/A converter chip(5Vpp output quantization error is less than 1mV), 250MSa/s sampling rate and 14bits vertical resolution. Can output up to 97 groups of functions/arbitrary waveform: 33 groups of preset waveform and 64 groups of user-defined waveform. 64 groups of arbitrary wave storage function, each one of waveform storage depth is 8192 points * 14bits. Various modulation types: AM, FM, PM, ASK, FSK and PSK modulations. Sweep Function: linear sweep and logarithmic sweep functions; 0.01s-999.99s sweep time; forward, backward and roundtrip sweep directions. VCO Function(Voltage Control Output): voltage controlling frequency/amplitude/offset/duty cycle and PWM modulations. Burst Output Function: there has manual trigger, internal CH2 trigger and external trigger for your options. It can output 1~1048575 pulse trains. Frequency Meter Function: Max. frequency workable is 100MHz and Min. frequency workable is 0.01Hz. Counter Function: 2 coupling measure modes including DC coupling and AC coupling. Support two or more signal generators connected to achieve multi-channel output, the maximum support 16-channel synchronous output. Completely independent dual channels output, synchronizing operation between channels. Precisely adjust the phases of the two channels, Precision can be 0.01. High Amplitude Resolution: the minimum amplitude resolution can reach 1mV, amplitude range is 0Vpp~20Vpp. Duty-cycle of each channel can be adjusted independently(0.01%-99.99%), the adjusting resolution is 0.01%. -10V~+10V DC offset range, offset resolution is 0.001V. Storage Function: can save 20 groups of parameters set by the user and extract at any time. Communication Function: all functions can be controlled by PC program and the communication protocol is open for secondary development. Output Short-circuit Protection: all channels can work more than 60 seconds when the load is short-circuited. Arbitrary Waveform Editing Function: user can edit arbitrary wave on PC and then download to output from the instrument.
