Timing Frequency Series
SDI-361B
SDI-361B can output 20MHz sinusoidal signal with high stability and low phase noise, and it can receive external 1PPS signal to tame local clock. There are indicators on the front panel of the equipment to indicate various working states, and the working status information of each module of the equipment can be automatically reported to the user’s monitoring computer through the RS422 interface. The equipment uses 12V direct current.
Features
- Small size & High precision
- High reliability& Excellent quality & Low phase noise
- Suitable for harsh and complex environments
Application
- Satellite network clock reference equipment
- Starlink system gate station clock equipment
- Communication reconnaissance terminal frequency reference
