The Rigol MSO5102 is a 100 MHz mixed-signal oscilloscope built for signal analysis in engineering and laboratory environments. It combines two analog channels with 8 GS/s real-time sampling, 100 Mpts memory per channel, and 16 digital channels for comprehensive waveform capture and debugging. An integrated arbitrary waveform generator, serial bus triggering and decoding, and waveform recording capabilities make it suitable for complex signal characterization across analog, digital, and protocol-level measurements.
