The Rohde & Schwarz HMO3042 is a 2-channel mixed-signal oscilloscope delivering 400 MHz bandwidth and 4 GSa/s real-time sampling for simultaneous analog and digital signal analysis. Built on the R&S®HMO3000 Series platform, this instrument combines deep 8 Mpts memory with integrated MSO functionality and 8 or 16 logic channels via optional probes, making it ideal for embedded systems debugging and complex signal characterization.
