REF-V01-MO

Product catalog summary

Overview
The REF-V01-MO is a high-stability signal generator designed for telecom and broadcasting applications, producing frequencies such as 2.048 MHz, 16.384 MHz, 5 MHz, and 10 MHz. It features a thermoregulated oscillator (OCXO) with minimal frequency drift, ensuring stability over time and temperature.

Synchronization Systems
The device uses two systems for tuning the internal oscillator: GPS synchronization via NAVSTAR and an external reference signal. The GPS system provides global, all-weather synchronization, while the external reference can be a sine or square wave, useful when GPS is unavailable.

Automatic Management
REF-V01-MO automatically manages both synchronization systems, allowing users to set one as a backup. It monitors GPS conditions and generates alarms if synchronization errors exceed 50ns.

External Reference
The external reference system supports frequencies like 16.66 kHz, 2.048 MHz, 5 MHz, and 10 MHz. It tracks frequency deviations over time, providing data for stability evaluation.

Control and Management
Management is possible via a front panel display and keyboard or a PC software package, facilitating installation and providing alerts and information.

Digital Instruments REF-V01-MO Signal Generator Tuned by GPS and External Reference REF-V01-MO is a synthesizer of reference signals. Its main application is related to generation of high-stability sample frequencies, i.e. the 2.048 MHz or 16.384 MHz (Telecom applications) or 5 MHz and 10 MHz (Broadcasting applications). The sample frequencies generated by REFV01-MO are extremely stable both for time and temperature. The device internally contains a high stability thermoregulated oscillator (OCXO), with minimum frequency drift. REF-V01-MO also implements two systems used to tune the internal...

Digital Instruments REF-V01-MO Signal Generator Tuned by GPS and External Reference The second system used by the REF-V01-MO for the control of the stability of the internal oscillator uses an external sample of frequency. This frequency may be chosen among the most famous, i.e. 16.66 kHz, 2.048 MHz, 5 MHz, 10 MHz. The signal defined External can be both a sine wave and a square wave form with TTL levels. The use of an external frequency reference may be useful in cases when there is the need to satisfy the lack of a GPS reference (failure, maintenance by the operator,…). The stability obtained...
