These signals, combined with differential capability, are valuable for making high-speed broadband measurements in many fields such as time domain reflectometry, semiconductor testing, gigabit interconnect and port testing, and in radar systems. High-speed differential data is becoming the dominant measurement challenge in digital, computing, interconnect and telecommunications systems. Despite this need, cost- effective, fast-transition differential pulse generators were hard to find ... until now. Key specifications A versatile, portable pulse generator The PicoSource PG900 Series of low-jitter triggered differential USB pulse generators PicoSource PG911 and PG914 offer a range of advanced features: Integrated 50 SMA(f) step recovery diode outputs < 60 ps single-ended pulse transition time The pulse outputs are optimized for broad spectral content (fastest transition Two 2.5 V to 6 V variable amplitude outputs time) to best suit spectral and time-domain transmission and reflectometry 1 ns timing deskew in 1 ps steps measurements 20 dB 10 GHz SMA(m-f) attenuators supplied fitted to SRD pulse outputs The internal clock provides stand-alone, self-triggered operation Trigger input and output allow the pulse generators to source or respond to system PicoSource PG912 and PG914 triggers External 50 N(m) positive and negative tunnel diode pulse heads Differential outputs ensure that the proliferation of gigabit differential interconnects < 40 ps pulse transition time and systems (such as SATA, USB3, HDMI, Ethernet) can all be addressed Fixed 200 mV output amplitude Essential to any differential measurement is the ability to adjust for small but 500 ps timing deskew in 1 ps steps significant velocity and path length differences that are bound to exist in any Inter-series N(f)SMA(m) adaptors included with pulse heads measurement setup. The PicoSource PG900 pulse generator outputs can each be All PicoSource PG900 models adjusted (time-skewed) by 1ns (integrated pulse outputs) or 200ps (tunnel diode pulse Differential outputs heads) in 1 ps increments to deskew path differences before the measurement, or to 200 ns to 4 s pulse width deliberately stress a transmission path with timing skew. Adjustable 1 s to 1 s internal clock period Despite their small size and portability, PicoSource pulse generators have plenty of Typical 3.0 ps RMS jitter relative to external trigger drive capability, with integrated step recovery diode outputs of up to 6 V pk each into 50. Thats a powerful 12 V pk differential pulse amplitude to drive lossy paths or stress system ports. Outputs are adjustable in 10 mV steps down to 2.5 V pk. An adjustable amplitude limit is provided to protect sensitive devices, and 20 dB attenuators are supplied fitted to the pulse outputs for small-signal optimal match applications.
