Tektronix 11801C Digital Sampling Oscilloscope, DC To 50-Ghz Bandwidth

The Tektronix 11801C is a microprocessor-based digital sampling oscilloscope delivering DC to 50 GHz bandwidth for high-speed waveform acquisition and analysis. With 7 ps rise time and 10 femtosecond sampling intervals, it captures transient events with exceptional temporal resolution. The modular architecture accommodates up to four dual-channel sampling heads across eight plug-in slots, expandable to 136 channels via SM-11 multichannel units. Standard eight-channel configuration scales to meet demanding measurement requirements in R&D, manufacturing, and test environments.
