Digital Instruments EASYREF Signal Generator Tuned by GPS

Digital Instruments EASYREF Signal Generator Tuned by GPS 1 Overview EASYREF is an high stability Time & Frequency generator. The high stability is obtained by disciplining algorithms controlled by GPS receiver. EASYREF in the standard version provide 10 MHz frequency reference and 1PPS time reference as well as Etrhernet interface for LAN synchronization by NTP protocol. EASYREF is very flexible for all applications where high stability Time & frequence reference are needed in very small size. The unit is extremely compact and can be mounted on Omega DIN rail Equipment can be interfaced...
