GENERAL INFO
Stable frequency sources are crucial for test equipment, references and synchronization of the telecommunication networks.
To achieve this, the OSA 2230 BVA Frequency standard houses two independent 5MHz state of the art SC cut
crystal BVA 8607 oscillators . These BVA oscillators are the industry standard alternative to compact atomic
clocks (over 10’000 BVA 8607 oscillators have been shipped). The housing is a 19” subrack. Separate
frequency control is provided. Signal distribution is made via BNC connectors mounted on the back panel.
Main ApplicationS
Measuring and calibration equipment
Frequency standard
GPS and Loran C equipment
