Features: Adopt 320*240 2.4 TFT color LCD display, simultaneously display parameters of CH1 and CH2. Ability to reproduce patterns of custom waveform. Use soft silicone keys instead of traditional patch keys, high sensitivity and convenient for operation. Using DDS direct digital synthesis technology to generate precise, stable and low distortion output signal. Max. output frequency(sine wave) up to 15MHz/30MHz/60MHz(Optional), 266MSa/s sampling rate and 14bits vertical resolution. Completely independent dual channels output, synchronizing operation and adjustable phase difference. Great improvement for square wave performance, square frequency range up to 15MHz with no distortion. 60 groups of arbitrary wave storage function, memory depth of each group is 2048*14bits. High frequency accuracy and resolution: frequency accuracy up to 10^(-6) magnitude, total range frequency resolution is 0.01uHz. High amplitude resolution: the minimum amplitude resolution can reach 1mV, amplitude range is 0Vpp~20Vpp. Duty-cycle of each channel can be adjusted independently, the adjusting resolution is 0.1%. Sweep function: linear sweep and logarithmic sweep functions; 0.1s-999.9s sweep time; forward, backward and roundtrip sweepdirections. With pulse trains burst output function: allow the unit output 1~1048575 arbitrary pulse trains. Measurement functions: can measure signal frequency, cycle, positive/negative pulse width and duty cycle; 1Hz~100MHz frequencyrange. -9.99V~9.99V DC offset range, offset resolution: 0.01V. With digital signal output function, CMOS output range 0~10V. Storage feature: can store 100 groups of parameters set by the user and extract at any time. Counter function: with DC and AC coupling modes. Arbitrary wave editing function: user can edit arbitrary wave on PC and then download to output from the instrument. Communication function: the PC can be used to control the instrument. With output short-circuit protection: all signal output can work 60s under load short-circuit condition.
