    Furaxa Inc. hardware products are warranted against defects in materials and workmanship for a period of two (2) years from the date of shipment of the product. During the warranty period, Furaxa Inc. shall, at its option, either repair or replace hardware, software or firmware products which prove to be defective.

    PCI bus systems using supplied drivers for Windows 7™, Vista™, XP™ or 2000™. In addition to dual synthesizers, the SYNTH300-TRIG board has two TTL inputs which can be used to dynamically switch between up to four frequency profiles, for a variety of dynamic waveform synthesis applications (frequency/phase modulation, triggered quadrature frequency sweeping, etc.).

  • Page 6: Specifications

    Each DDS has 14-bit phase resolution, allowing fine phase adjustment of each DDS core. Further, the Synth300-TRIG boards incorporate dedicated circuitry and firmware to synchronize the two DDS cores at 1GHz, allowing advanced functionality such as synchronous frequency sweeping of two sinusoids with a fixed phase relationship (e.g.

    Alternatively, a single SYNTH300-TRIG -HS can be used to provide this clock to other SYNTH300-TRIG devices. In this setup the SYNTH300-TRIG -HS is software configured to use its own internal clock while the SYNTH300-TRIG devices are software configured to use an external clock (only the non-HS models allow for an external clock input).
