The NR8403-RO in a versatile modular package bring stability to almost any location. Wide power operating range with optional GNSS locking to further enhance long-term stability (NR8403-RG). The Rubidium source affords outstanding holdover stability (<1 ppb/year). The low noise OCXO adds a low noise OCXO that can be also vibration isolated to reduce mechanical induced phase noise . Phase noise < 155 dBc/Hz at 10kHz. Unit may also be locked to an external 10 MHz or PPS. Popular in scientific, calibration labs and satellite up-links.
Harmonics <40 dBc
Excellent holdover stability < +-1ppb/year
Outputs are fault protected and monitored continuously
Built-in test circuitry throughout the design
Available with and without display
10 and 50 MHz available
Need low noise and GNSS locking? NR8403-ROG
Kits are available that include antenna, cables and power supply. Several features can be customized at the factory – frequencies other than 10 MHz either from a unique crystal or with a built-in synthesizer that is GNSS-locked. Time stamping capability to 100ns resolution. To meet unique requirements, we have shipped product with output features requiring a custom amplitude, square wave output, high voltage and high current drive.
