The Rigol DS1052D is a mixed-signal oscilloscope integrating a 50 MHz bandwidth analog scope with a 16-channel logic analyzer on a single platform. It captures both analog and digital signals simultaneously, delivering 1 GSa/s real-time sampling on analog channels and 200 MSa/s on logic channels. The 5.7″ TFT display presents waveforms across a 5 ns/div to 50 s/div timebase range, supported by up to 1 Mpts memory depth for detailed transient analysis. This instrument addresses embedded systems development and mixed-signal design verification where synchronized observation of analog behavior and digital state is essential.
