2 hz - 35 KHZ audio oscilloscope C51 simple oscilloscope Product use: One, the system structure STC12C5A60S2 MCU internal AD sampling; LCD12864 display waveform; The LM393 of hysteresis comparator measured small signal frequency, To simplify the design, to the greatest extent through capacitance directly into the MCU AD input signal, there is no input, by adjusting the R10 waveform in the centerline location. Second, the basic functions 1, per time: 10 5 ms/ms/ms/ma / 1, 2, 500 us 200 us / 100 / us/us / 20 us 50. Basic can show 20 ~ 20 kh signal. 2, the voltage of each cell: 1 V / 0.5 V / 0.2 V. About 3, HOLD the function: after freeze waveform, translation can show a total of 4 screen (including the current screen) waveform. 4, take 5 KHZ square wave output all the way. 5, power to keep users to set parameters. The function of the power supply voltage stability the demand is higher, under voltage or over voltage parameters will be washed away or not boot properly. Third, directions for use 1, K6 keys, grid line style transformation: (1) the scatter and grid line, the style reference from the previous teacher wu DIY series oscilloscope display style; (2) only grid line; (3) blank. Three kinds of style switch in turn. 2, K1 key, waveform freezing and normal display switch. Waveform frozen state, the lower left corner shows that local frequency will show HOLD MODE. 3, K2 / K3, each grid voltage adjustment, 1 V / 0.5 V / 0.2 V switch in turn. 4, K4 / K5, normal display, adjust per time; Waveform after freezing, the realization of waveform translation. So under the waveform frozen can't be adjust time! Delivery Quantity :1 pcs Payment Policy: We ONLY accepted PayPal payment.
