The Tektronix SD-30 is a single-channel sampling head delivering greater than 40 GHz of bandwidth for precision time-domain analysis of ultrafast signals. With an 8.8 ps calculated rise time and 8-bit vertical resolution, it captures transient phenomena in opto-electronic component testing, process control, and signal troubleshooting. The SD-30 integrates into Tektronix 11800 Series Digital Sampling Oscilloscopes, the SM-11 Multi-Channel Unit, and CSA 803 Series Communications Signal Analyzers through a precision 2.9 mm connector (K-type) that is mechanically compatible with SMA and 3.5 mm connectors.
