The USB-connected PG900 Series offer differential outputs with programmable de-skew in 1ps steps. De-skewing allows timing inequalities in test connections and fixtures to be nulled out, or the deliberate introduction of timing skew to stress-test a system. Each of the outputs can also function in single-ended mode.
These generators can simulate broad spectral signals driving a 50 ohm cable to a device under test, with the reflected or transmitted pulse monitored and displayed by a broadband or sampling oscilloscope, such as a Picoscope 9300 20GHz Sampling Oscilloscope. This Time Domain Reflection analysis is widely used for testing very fast data paths such as Ethernet, USB, HDMI, SATA, RF, radar and microwave devices, cables, networks and other high speed equipment.
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 < 60ps 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 less than 40ps with fixed 200mV amplitude 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, with an internal trigger clock offering extensive width, period, and hold-off adjustments. Pulse edge jitter with respect to the trigger input and output is less than 3ps RMS.
Connected via USB to a PC running Microsoft Windows, the PicoSource PG900 Generators offer a compact and economical instrument, with the added advantage of the PC’s high-resolution graphical display and easy setup via keyboard, mouse, or touchscreen. The reasonable cost and extreme portability of these instruments now brings RF and microwave test to many on-site measurement situations, and thus can form an essential part of a broadband technician’s toolkit.
Made by Pico Technology, Europe’s award-winning oscilloscope adapter manufacturer, the PicoSource PG900 Series Differential Pulse Generators are available now starting at $7,382, with graphical control software and a 2-year warranty included, from Saelig Company, Inc. their USA technical distributor.
