Page 5: Introduction
1.0 Introduction The FC-250-10P is a Low Noise Frequency Converter for Optical to RF Signals. This instrument can be used to generate low noise 10 MHz, 100 MHz and 1PPS signals that derive their phase noise and stability from an external 800-1650 nm pulsed optical signal with a repetition rate of 250 MHz.
Page 6: Safety And Preparation For Use
2.0 Safety and Preparation for Use The FC-250-10P was designed for indoor use only and is not intended for operation outdoors or in a wet environment. Inspect the instrument and power cords for damage before first use. 2.1 Electrical Safety and Preparation for Use Voltages capable of causing injury or death are present in this instrument.

Page 10: Installation
2U, half rack enclosure. Connecting Power The FC-250-10P ships with a standard North American, European, or Chinese IEC power cord. Locate the AC POWER entry module on the rear of the enclosure and connect the power cord.
Page 11: Operation
6.0 Operation Plug the power cord into an appropriate AC power outlet. Once AC power is supplied to the FC-250-10P the LED on the front panel labeled POWER will turn on. After the AC power has been applied, an optical signal may be applied to the input fiber optic connector.
Page 12: Troubleshooting
Disconnect the power cord and remove the top cover. Check the main AC power fuse and power cord. If the fuse is blown replace with same type and rating. Please contact SDI if the fuse blows again or if the event that caused the fuse to blow is not known.
