    PXIe-3352 User Manual Chapter 1 Overview and Features The PXIe-3352 (Figure 1-1) is a Rubidium/GPS module for use in PXI hybrid and PXI Express slots in a PXI mainframe. It provides a basic accuracy of 5e in free- run mode, but, given an external GPS antenna (not included) and a view of the sky, can be disciplined to GPS satellites for improved timing accuracy.

  • Page 10: Functional Description

    GPS module when needed. All controls are via the PXIe bus in a PXIe compatible mainframe. Figure 1-2, PXIe-3352 System Configuration Example The PXIe-3352 card comprises three functional systems as follows: • The Rubidium Block •...

  • Page 11: Rubidium Block

    PXIe-3352 User Manual Rubidium Block The major component of the PXIe-3352 is the Rubidium block. The Rubidium block is a multifunctional Rubidium Frequency Standard. It is one of the smallest atomic clock standards currently available, where the accuracy and stability are derived from a quantum energy transition that occurs in a free Rubidium atom.

  • Page 12: Rs232 Interface

    The PXIe interface allows the FPGA to communicate data and commands between the PXIe chassis and the PXIe-3352. The FPGA then translates the data and commands via 9600 baud rate TTL serial to the GPS IC and via 9600 baud rate RS-232 to the Rubidium block.

    Publication No. 981049 Rev. B PXIe-3352 User Manual External DC Power Supported If the PXI mainframe is powered down, power may still be applied to the Rubidium oscillator via a front panel external DC power input. This keeps the Rubidium oscillator very stable over time and eliminates the effects of retrace.
