T220-X PXI Timing Card
Learn about our PC timing solutions
The T220-X PXI timing card supports a variety of reference inputs and outputs, allowing different combinations to be used as needed to provide high-precision time information to computer systems and also to provide external time services. It supports GPS, 1PPS, and TOD signals as reference inputs, and outputs PTP, B-code, and TOD+1PPS signals for external time services. The card transmits time information and timer interrupt signals to the computer via the PXI interface, synchronizing computer software time with the card's time. It also features a built-in, highly stable, oven-controlled crystal oscillator. Even if all reference time sources are disconnected, the card's internal high-stability crystal oscillator can continue to operate within a certain time accuracy range for a specified period of time, thereby continuing to provide a relatively accurate time signal to the computer system and improving the reliability of the product's continuous operation.
Applicable fields: scientific research measurement, communications, electricity, transportation, industrial automation, etc.
