Pico USB Pulse Generators
Triggerable Differential Pulse Generators "PicoSource PG900"
The new PicoSource® PG900 Series pulse generators are high-speed, low-cost instruments for the USB Port of a computer 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.
Applications for the Superfast Step Generators
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.
Different PicoSource Models
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.
Accessories for the PG 900 Pulse Generators
Pico Technology also offers a complete range of TDR and TDT accessories to partner these differential pulse generators with its PicoScope 9000 12 GHz and 20 GHz sampling oscilloscopes.
