National Instruments Corporation Astronics PXIe-3352, Rubidium Reference Source with GPS
The PXIe-3352 is a high-performance rubidium reference source with integrated GPS receiver, designed and manufactured by Astronics Test Systems for use in PXI Express (PXIe) test systems. This module provides a highly stable 10 MHz reference output, leveraging a rubidium oscillator disciplined by GPS signals for long-term accuracy and stability. The PXIe-3352 is ideal for applications requiring precise frequency and timing synchronization, such as RF and microwave test systems, communications, and aerospace/defense testing. It features automatic switchover between internal rubidium and external GPS reference, ensuring continuous operation and reliability. The module is compatible with PXIe chassis and can be integrated into automated test setups, providing traceable timing to UTC via GPS. The PXIe-3352 supports remote monitoring and control through software interfaces, enabling flexible system integration and management.
