JDS2800 Adopt 320*240 2.4" TFT color LCD display,the instrument adopts the Direct Digital Synthesizer(DDS) technology and provides stable, precise, pure and low distortion signals. Max. output frequency(sine wave) up to 15MHz/40MHz/60MHz(optional), 266MSa/s sampling rate and 14bits vertical resolution .Use soft silicone keys instead of traditional patch keys, high sensitivity and convenient for operation; FEATURE ?Great improvement for square wave performance, square frequency range up to 25MHz 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 FUNCTION ?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.Measurement functions: can measure signal frequency, cycle, positive/negative pulse width and duty cycle; 1Hz~100MHz frequency range 2 YEARS WARRANTY? It's a great testing or measuring instrument for electronics engineers, electronic laboratory, teaching and researching. MULTIFUCTION? 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 : all signal output can work 60s under load short-circuit condition
