USB Oscilloscope Disco-2 is a great tool for your hobby and professional projects!
In the same box you get USB Oscilloscope, USB Logic analyzer, Spectrum analyzer, Signal recorder and Logic generator - the whole laboratory for the affordable price!
Simply connect the device to the computer USB port, run the Windows application and you can analyze the UART, SPI, I2C and 1-Wire interfaces besides the analog signals.
USB oscilloscope Disco-2 has the following operation modes:
- 2-channel XY (or AB) Oscilloscope: marker measurements, triggering (with absolute, differential, external trigger modes) and adjustable pretrigger, signal voltage and frequency measurement, filtering, etc.
- 16 (8)-channel Logic Analyzer: marker measurements, triggering (edge, level, mask) and adjustable pretrigger, external clocking (triggering), preset pulse miss, preset bit sequence/edge, decoding of the interface UART, SPI, I2C, 1-Wire, etc.
- 8-channel Logic Generator: tabular waveform formatting or direct timing chart plotting with mouse on the screen, etc.
- 2-channel Spectrum Analyzer: marker measurements, klirr-factor measurement, different window functions, filtering, etc.
- 2-channel Signal Recorder: marker measurements, option to add 99 markers with comments, maximal, minimal and average voltage measurement for each channel, waveform record within several tens of hours, etc.
