Using DDS direct digital synthesis technology to generate precise, stable, low distortion output signal; CH1 and CH2 completely symmetrical two channels, each channel can be independently set the parameters ; Supports user-defined waveforms, each arbitrary waveform memory depth 2048 * 12bits, 250MSa / s sampling rate; has burst burst output, selectable manual trigger, internal and external trigger CH2 trigger three trigger modes that allow the unit to any output 1 ~ 1048575 bursts ; Measurement functions: instrument comes with 100MHz frequency counter functions and pulse counter functions ; Waveform generator up to 12 bits wide, the output waveform is more delicate, waveform distortion is reduced magnitude
