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, 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!
The new PicoSource® PG900 Series pulse generators are high-speed, low-cost instruments for use in single-ended and differential pulsed measurement applications. 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 essential for many of the high-speed broadband measurements that we need to make; for instance in time domain reflectometry, semiconductor test, gigabit interconnect and port test, and in radar system test.
The generators are typically used to drive broad spectral content into a 50 ohm cable, connector, RF semiconductor or other device under test. The reflected or transmitted pulse can then be monitored and displayed by a broadband or sampling oscilloscope. Known as Time Domain Reflection or Transmission analysis, these techniques offer an alternative to vector and scalar network analysis. They are widely used to speed the development, evaluation and testing of high-speed data paths such as Ethernet, USB, HDMI and SATA, and RF, radar and microwave devices, cables, networks and equipment.
Unlike traditional, bulky and expensive benchtop instruments, the PicoSource PG900 generators are compact USB devices that connect to a PC running Microsoft Windows. This gives the advantages of leading microwave performance in a compact and portable instrument, a high-resolution graphical display, and easy setup by means of keyboard, mouse or touchscreen. The low cost and portability of these instruments can bring RF and microwave test out of the lab and into the world of on-site measurement. With all these advantages, the new pulse generators will have a role in the toolkit of every broadband equipment designer, installation engineer and repair technician.
“Unusually and yet vital to the modern differential measurement challenge, the PicoSource PG900 pulse generators have deskewable differential outputs adjustable to 1 ps resolution,” explained Business Development Manager Mark Ashcroft. “This allows timing inequalities in test connections and fixtures to be nulled out; or the deliberate introduction of timing skew to stress-test your system.” Each of the outputs can also operate in single-ended mode.
The PicoSource PG900 Series offers two triggered step-generation technologies to suit different applications. The PG911, with integral step-recovery diode outputs, offers a transition time of < 60 ps with a large and adjustable output swing of 2.5 V to 6 V on each output. These pulses can support high dynamic range and long-distance measurements and can exercise all signal amplitudes in most transmission systems and devices. The PG912 uses external tunnel diode pulse heads to deliver a faster transition time of < 40 ps with fixed 200 mV amplitude right at the interface plane. A third model, the PG914, combines both technologies in one space-saving, economical unit.
All models feature low-jitter external trigger input and output and an internal trigger clock with comprehensive width, period and hold-off adjustments. Pulse edge jitter with respect to the trigger input and output is less than 3 ps RMS.

| Additional Info/Comments | 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. |
