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).

Essential to any differential test or measurement is the ability to adjust for small but significant velocity and path length differences that are bound to exist in any measurement setup. The PG900 pulse outputs can each be adjusted (time-skewed) in 1 ps increments to deskew path differences before the measurement, or to deliberately stress a transmission path with timing skew.

Despite their small size and portability the PicoSource PG900 generators pack quite a punch, with integrated Step Recovery Diode outputs of up to 6 V pk each into 50 Ω. That’s a whopping 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. A user-settable amplitude limit is provided to protect more sensitive system ports and 20 dB attenuators are supplied fitted to the pulse outputs for small-signal and optimum-match applications.

The PicoSource PG900 Series generators are USB controlled from a Microsoft Windows PC running PicoSource PG900 software that is provided with the product. This is a very straightforward control application featuring a helpful graphical display of the pulse, limits and trigger settings as they are applied. Default and User pulse settings can be saved for future recall.

The pulse and trigger waveform displays can be toggled between three timebase settings to show the timing relationship of trigger and pulse, the pulse period or the pulse train being output.
