______________________________________________Purpose:The DSS-31 oscilloscope is a standalone portable device with a graphic display and microcontroller control, and is designed to study electrical signals in the frequency range from zero to several 1MHz.The oscilloscope uses Anti-Aliasing technology, which reduces the discrete distortions of the waveform and brings the signal display closer to the typical analog oscilloscopes. Main technical characteristics: Maximum sampling rate of 2 MHz for single signals, 20 MHz for periodic signals; Maximum bandwidth by-3dB level (typical value) 0 ... 5 MHzInput impedance 1 MΩ, 25 pF;Sensitivity 10mV, 20mV, 50mV, 0.1V, 0.2V, 0.5V, 1V, 2V, 5V, 10V, 20V / div;Sweep 0.1 μs, 0.2 μs, 0.5 μs, 1 μs, 2 μs, 5 μs, 10 μs, 20 μs, 50 μs, 0.1ms, 0.2ms, 0.5ms, 1ms, 2ms, 5ms, 10ms, 20ms, 50ms, 0.1s, 0.2s, 0.5 s, 1s, 2c, 5s, 10s / div;Maximum input voltage 100V (ampl.);8-bit vertical resolution;Sweep start modes: automatic, standby, single, manual;Graphic display monochrome 128x64 pixels;The number of stored waveforms 2 records of 200 samples;Interface language is Russian, English;Off timer 2, 5, 10, 15, 20, 30, 45, 60 min., Off;LCD backlight adjustable, 6 levels;Output for tuning the probe with a divider ≈1.22 kHz, (4.5 ÷ 4.75) V (ampl.);Power supply external (5.0 ± 0.2) V, 100 mA;Display of measured parameters of a signal with 2 or 4 parameters for choice;Indication of the frequency of the test a periodic signal of 0.000 Hz ... 9999 kHz (4 bits);Indication of the launch level of the sweep arrow icon;Waveform Vertical Offset on the screen ± 9.6 div. (10 mV / div); ± 3.2 div. (20mV ... 10 V / div.); ± 2.4 div. (20 V / div.);Horizontal offset waveforms on the screen 0.0 ... 10.0 div .;Automatic function switch sweep and sensitivity limits (separately);Sound accompaniment of pressing the control buttons (adjustable volume);Settings menu;Files:Bill of materialsSchematics diagramFirmware (fuses: LOW: 0x1F, HIGH: 0xC7)_________________________________________
