MSO71254C

The Tektronix MSO71254C is a high-performance 12.5 GHz Mixed Signal Oscilloscope belonging to the MSO70000C Series. Designed for deep system-level debug of high-speed digital designs, it features 4 analog channels and 16 logic channels. It delivers real-time sample rates of up to 100 GS/s on 2 channels (50 GS/s on all 4 channels) and a 12.5 GS/s sample rate with 80 ps timing resolution on digital channels. The instrument is equipped with Pinpoint triggering, a hardware-based 6.25 Gb/s serial pattern trigger, iCapture analog multiplexing of digital lines, and comprehensive serial decoding options.
