Adopt 320*240 2.4in TFT color LCD display, simultaneously display parameters of CH1 and CH2; Ability to reproduce patterns of custom waveform; 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 Use soft silicone keys instead of traditional patch keys, high sensitivity and convenient for operation; 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%. With output short-circuit protection: all signal output can work 60s under load short-circuit condition Max. output frequency(sine wave) up to 15MHz/40MHz/60MHz(optional), 266MSa/s sampling rate and 14bits vertical resolution;Sweep function: linear sweep and logarithmic sweep functions; 0.1s-999.9s sweep time, forward, backward and roundtrip sweep directions.With pulse trains burst output function: allow the unit output 1~1048575 arbitrary pulse trains Completely independent dual channels output, synchronizing operation and adjustable phase difference;Measurement functions: can measure signal frequency, cycle, positive/negative pulse width and duty cycle; 1Hz~100MHz frequency range. -9.99V~9.99V DC offset range, offset resolution: 0.01V. With digital signal output function, CMOS output range 0~10V Great improvement for square wave performance, square frequency range up to 25MHz with no distortion; 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
