Rubidium for PXI: Astronics PXIe-3352


The Astronics PXIe-3352 is the world’s first PXI rubidium and combines a rubidium oscillator with a GPS receiver into a single, high precision instrument.

As the first test instrument to combine a PXI rubidium source with GPS assist technology, the new PXIe-3352 will be well-suited for use in a variety of commercial and military applications.

The PXIe-3352 is used in either a PXI hybrid or PXI Express slot in a PXI mainframe to provide high precision time and frequency accuracy for measurement equipment. Useful for telecommunications timing, calibration and metrology, and RF subsystems, the PXIe-3352 can be disciplined with GPS satellites for stability and improved accuracy.

Key features include:

  • Long-term stability with GPS assist
  • High system density due to dual width PXI Express module approach
  • Sine and square wave outputs 
  • Free run mode or lock to a built-in GPS receiver
  • Power maintenance through shutoff with external power input

Units will be available later this year and sold through the NI sales channel.
