Benefits of the PicoSource PG912, Tunnel Diode 40 ps Pulse Heads

  • Differential pulse generator for USB 2.0.
  • 50 Ω positive and negative tunnel diode pulse heads.
  • For TDR, semiconductor testing and many other applications.

PicoSource PG912 - USB differential pulse generators

The fast-transition pulse can stimulate a transmission path, device or network with a broad spectrum signal in a single instant. Such a pulse is very useful for many of the high-speed broadband measurements that we need to make; for instance in time-domain reflectometry/TDR, semiconductor test, gigabit interconnect and port test and in radar. Differential high-speed data in particular dominates the measurement challenge in our digital, computing, interconnect and telecommunications systems. Surprisingly, cost-effective fast-transition differential pulse generators have been very hard to find... until now!

  • Three PicoSource models:
    • Integrated 60 ps pulse outputs: PG911.
    • Tunnel diode 40 ps pulse heads: PG912.
    • Both output types: PG914.
  • Tunnel diode pulse heads:
    • Differential with deskew (±500 ps timing deskew in 1 ps steps).
    • <40 ps transition time.
    • Fixed 200 mV output amplitude.
    • External 50 Ω N(m) positive and negative tunnel diode pulseheads.
    • Inter-series N(f)–SMA(m) adaptors included with pulse heads.
