DSO2D15 7 Inch TFT LCD screen oscilloscope is fine quality and low price, with the characteristics of 150MHz band width and 1GSa/s sampling rate, built-in 25MHz signal generator, support any type wa-veoutput, with 14 types of trigger mode, There are five kinds of serial protocol triggering and decoding, 32 kinds of automatic measurement, with the function of statistical analysis of test results, with a wealth of SCPI remote control instructions. It is wildly used in communication, aerospace, national defense, embedded systems, computers, research and education and a lot of other industries and fields. Come on and try it. Features: Has 2 channels, and each channel with independent knob control. 150 MHz ana-log bandwidth and 1GSa/s sampling rate. It has a 7-inch TFT LCD screen, 800 * 480 pixels, 16 million display colors (24bit true colors). Built-in a 25MHz signal generator, support arbitrary wa-veburst output, support modulation wa-veform output. It can save settings, wa-veforms, reference wa-veforms, CSV, pictures and other data formats, with 5-digit digital voltmeter and 6-digit hardware frequency counter functions. Support 32 kinds of automatic measurement and statistics functions, real-time statistics of minimum, maximum, standard deviation and other statistical information. It has two sets of digital voltmeter functions, supports threshold testing, and can realize free measurement on the screen. With abundant SCPI remote control commands, it can provide a lot of types of peripheral interfaces, such as USB Host/Device. It can save 10 sets of reference wa-veforms, CSV wa-veforms, settings and USB one-key screenshot function. Serial bus triggering and decoding function, providing protocol monitoring function. 8M storage depth reduces wa-veform distortion and restores real wa-veforms. XY mode supports dual window display.
