The PicoSource PG900 Series are low-jitter triggered differential USB pulse generators. Pulse outputs are optimized for broad spectral content (fastest transition time) to best suit spectral and time-domain transmission and reflectometry measurements. An internal clock is provided for stand-alone, self-triggered operation and trigger input and output allow the generators to source or respond to system triggers. Differential outputs ensure that the proliferation of gigabit differential interconnect and systems can all be addressed (e.g. SATA, USB3, HDMI, Ethernet).
