A versatile, portable triggered differential USB pulse generator

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).

Step Recovery variable amplitude pulse

The positive (fast rise) and negative (fast fall) pulses are both ground referenced and each pulses in opposite polarity to their user selected amplitude. This amplitude (the 'mark') is held for the user-selected pulse width and then returns to ground. Further pulses are prevented for the user set hold-off period and thereafter will repeat at 40 ns after the next received trigger. When the internal clock is selected, the pulse will repeat at the user-set period and holdoff is inactive. An output trigger is generated 40 ns before every pulse, however initiated.
Pulse transition time is typically 55 ps and spectral content (compared with a simulated ideal infinitely fast edge) extends to around 13 GHz @ –10 dB.

Tunnel Diode Head fixed-amplitude pulse

The positive (fast rise) and negative (fast fall) pulses are both ground-referenced and each pulses in opposite polarity to its user-selected amplitude. This amplitude (the 'mark') is held for the user-selected pulse width and then returns to ground. Further pulses are prevented for the user-set holdoff period and thereafter will repeat at 40 ns after the next received trigger. When the internal clock is selected, the pulse will repeat at the user-set period and holdoff is inactive. An output trigger is generated 40 ns prior to every pulse, however initiated.

TDR applications with a PicoScope 9300 Sampling Oscilloscope

Controlled over USB from a single PC, the PG900 Pulse Generators can be used with a PicoScope 9300 Sampling Oscilloscope to realize Time Domain Reflectometry with the models that do not integrate that functionality (PicoScope 9301, 9302, 9321 and 9341).

TDT applications with a PicoScope 9300 Sampling Oscilloscope

Controlled over USB from a single PC, the PG900 Pulse Generators can be used with a PicoScope 9300 Sampling Oscilloscope to measure Time Domain Transmission with those models that do not include that function (PicoScope 9301, 9302, 9321 and 9341). They may also add the versatility of a remotely placed signal generator for long line or installed system testing with any of the PicoScope 9300 models.

TDT and crosstalk with a PicoScope 9341 Sampling Oscilloscope

Controlled over USB from a single PC, the PG900 Pulse Generators can be used with a PicoScope 9341 four-channel Sampling Oscilloscope for simultaneous Time Domain Transmission and Crosstalk assessment.
