Rubidium Frequency Standard
Novatech introduces the 2965AR Rubidium frequency standard. Housed in a small bench-top case, the standard contains an atomic time-base with a stability of 5 × 10㪣 per month. The product combines a 50 MHz direct digital synthesizer along with 10 MHz and 5 MHz outputs. This standard is suitable for use as external references for laboratory instruments or as a time-base for a variety of systems in industries like telecommunications and radar. The device uses an auto-adaptive disciplining algorithm, requiring no user intervention or tuning, that tracks a 1 pps source from a GPS1 smart antenna, or other 1pps source, and disciplines the rubidium oscillator. A 1 pps derived from GPS gives the standard accuracy at Stratum1 levels with 24 hour holdover of ۫µs (۫ × 10㪣). Three front panel BNCs provide sine wave outputs of 1 Vrms into 50Ω. The TTL-compatible 1 pps input and output signals are on rear panel BNCs.
