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. Adopt MagicPulse Technology, Low Jitter (RMS) 200ps. 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. Can output up to 99 groups of functions / arbitrary waveform, contains 35 groups of preset waveforms and 64 groups of user-defined waveforms.
Preset waveforms: Sine, Square (Duty Cycle adjustable), Pulse (Pulse width and cycle time can be set accurately), Triangle/Ramp, CMOS(0~12V), Four channels TTL, Exponential Rise, Exponential Fall, Noise, ECG, DC etc. Enable to store 64 arbitrary waveform data files, each one of waveform storage depth 8192 points * 14bits; (The longer the waveform storage depth, the more detail the waveform is saved, and the signal details can be restored with high precision.
) Various modulation types: AM, FM, PM, ASK, FSK and PSK modulations.
Sweep Function: it can sweep 4 properties of signals including frequency, amplitude, offset and duty cycle; It has Linear and Logarithm two sweep types; 0.01S ~ 999.99S sweep time; Up, Down and roundtrip sweep directions.
VCO Function (Voltage Control Output): can be achieved by an external input signal: voltage controlling frequency, voltage controlling amplitude, voltage controlling offset, voltage controlling 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.
100M Frequency Meter Function: it can measure frequency, period, pulse width and duty cycle. Max. frequency workable is 100MHz and Min. frequency workable is 0.01 Hz.
Counter Function: it has 2 coupling measure modes including DC coupling and AC coupling. This design can solve inaccuracy problem of AC coupling. Standard dual full functional channels which are equivalent to two independent generators.
Channel SYNC Function: support waveform copy and state copy between channels. Support two or more signal generators connected to achieve multi-channel output, the maximum support 16-channel synchronous output, the phase between each channel can be adjusted. Precisely adjust the phases of the two channels. Precision can be 0.01. Min amplitude resolution can be up to 1 mV. Amplitude range is 0~24Vpp. Duty-cycle of each channel can be adjusted independently 0.01 %- 99.99 %, the adjusting resolution is 0.01 %. -12V~+12V DC Offset function. Resolution 0.001V.
Save Function: it can save 20 sets user-set parameters and can be loaded at any time.
Communicating 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. Provide powerful waveform editing PC software. Users can download arbitrary waveform to this instrument after edit through PC program which is included in user CD. Adopt ABS plastic shell with table type design. Use 100-240V (AC) wide range voltage power supply.
