Up to eight 10 MHz & 1 pps outputs (opt.) GPS/GNSS disciplined 10 MHz Double-oven OCXO timebase FS752 GPS 10 MHz Reference The FS752 GNSS Disciplined Time and Frequency Reference provides calibrated time and frequency distribution to your laboratory. A built-in receiver tracks any of the four major GNSS constellations: GPS, GLONASS, BEIDOU, or GALILEO. The instrument comes with a double-oven OCXO timebase that has phase noise of less than -125 dBc/Hz at 10 Hz offset. 3D Step File FS752 Volatility Statement FS740 GPS/GNSS DO FS725 Rb Frequency Standard PRS10 Rb Oscillator FS735 Distribution Amplifier RF Signal Generator FS740 GPS/GNSS DO FS725 Rb Freq.

FS752 10 MHz GPS/GNSS Reference 10 MHz Phase Noise X 10 MHz Phase Noise FS752 10 MHz and 1 pps Distribution The FS752 provides five buffered 10 MHz outputs and two buffered 1 pps outputs. The 10 MHz outputs generate 1 Vrms into 50 Ω and may be used as frequency references for laboratory equipment. The 1 pps outputs generate 10 µs pulses, with 5 V CMOS logic and rising edges aligned to UTC. Up to eight additional 10 MHz and 1 pps outputs are available as rear-panel options . Stability (locked to GNSS) X Stability (locked to GNSS) FS752 Stability (locked to GNSS) The FS752 provides bias for a remote active GNSS antenna. The unit's GNSS receiver tracks all satellites in view, automatically surveys and fixes its position, then uses all received signals to optimize its timing solution. The FS752 time-tags the 1 pps output from the receiver, corrects the result for the receiver's sawtooth error, then phase locks the timebase to the GNSS 1 pps. The TDEV between two instruments is a few nanoseconds. If the GNSS signal is lost, the timebase is left at the last locked frequency value. The timebase will age or drift in frequency by less than ±0.05 ppm/year. You may choose to purchase a GNSS antenna from SRS, or a third party, or use an existing GNSS antenna at your facility. SRS timing receivers require a net gain (after cable losses) of +20 dBi to +32 dBi, which is a very common level from a variety of available active antennas and typical cable lengths. The antenna input to SRS timing receivers have a female BNC connector, provide +5 V bias, and have a 50 Ω input impedance. Stability (unlocked to GNSS) X Stability (unlocked to GNSS) FS752 Stability (unlocked to GNSS) SRS offers two antenna solutions, both of which have LNAs. All systems components have a 50 Ω characteristic impedance. For antenna details click here . The FS752 includes a configurable SPDT switch on its rear panel. By default, the alarm is set to assert whenever the FS752 loses lock to the GNSS signal, but the switch can also be set to monitor the health of the timebase or the instrument's holdover state. The FS752 can be controlled and queried over its USB port. The instrument is fully programmable using its extensive high-level command set, and there is also a free GNSSDO application that makes sending commands, viewing instrument status, and changing the configuration of the FS752 easy.
