ClockWatch Radio Sync
WWVB Receivers
The Ultralink receivers offered with Radio Sync provide
accuracy and precision at an affordable price. The receivers
receive VLF (very low frequency) radio signals broadcast by WWVB operated by
the National Institute of Standards and Technology (NIST). This accurate
time and date information is referenced to the United States Atomic Clock
Standard.
Each of these receivers feature:
- Microprocessor based control
- Factory tuned internal ferrite loop stick antenna
- Internal real-time-clock backup
- Serial connection to Windows computer via COM port
- Seamless integration with Radio Sync software
| Model 325 | |
|
The Ultralink Model 325 receiver incorporates a high quality ferrite
loop stick antenna, factory tuned for maximum sensitivity and selectivity. The
receiver uses base band amplification with crystal band pass filtering. A
demodulator provides a digital output corresponding to received signal data. A microcomputer processes WWVB signals, maintains
an accurate real time clock and hosts the serial communication interface.
Received data is correlated over time to set an internal real-time clock (RTC).
The RTC is driven by a precision quartz crystal for continuous accurate time
reference. Power circuitry provides internal operating voltages and maintenance. The 325 comes with a 25 foot interface cable, with a DB9 serial data connector.
