Local Oscillator Distributor (LOD)

Double 1:16 ultra low-noise RF signal splitter

The “Local Oscillator Distributor” (LOD) is a double 1:16 ultra low-noise RF signal splitter whose main functionality is the distribution of sine clocks with minimal degradation at short distances ( tens of meters). For large distance please consider to use the specifically designed timing products.

The system FPGAField-Programming Gate Array: an integrated circuit designed to be configured by a customer or a designer after manufacturing – hence the term field-programmable. See also is dedicated to configure and monitoring the RF signals. An embedded softprocessor is used to provide a simple remote interface to the users. It is complemented with an EPICS driver based on Asyn and StreamDevice module, fully compliant with the EPICS official specifications.

LOD can be handled through the Ethernet port and the SCPI protocol. This SCPI protocol was released as an additional layer for the IEEE-488.2 standard, used for controlling and monitoring the instruments through GPIB.

• 16 Optical Timing Ports for WR, PTPv2 and NTPNTP, or Network Time Protocol, is a widely used networking protocol that enables computers and devices to synchronize their system clocks with a reference time source. It ensures accurate timekeeping in computer networks by allowing devices to obtain precise time information from NTP servers, which are typically synchronized to highly accurate atomic clocks. NTP is essential for various applications and services that rely on synchronized time, such as network security, authentication, and data logging.
