100G-sample/sec real-time scope interleaves ADCs to reduce noise

摘要

Tektronix has announced the DPO (digital-phosphor-oscilloscope), DSA (digital-signal analyzer), and MSO (mixed-signal-oscilloscope) 70000C series, which simultaneously capture 100G samples/sec on two channels or 50G samples/sec on four channels. The higher sampling rate yields lower noise and increased numbers of data points on five-times-over-sampled 20-GHz waveforms. MSO models also include 16 logic-timing-analysis channels that each acquire 12.5G samples/sec.
