MSD-295
Precision Rubidium Standard 10MHz and 1PPS, GNSS disciplined generator.
The MSD-295 is a high-precision rubidium oscillator-driven generator of 10MHz and 1PPS reference signals. It delivers unmatched signal purity and frequency stability for 10MHz sine wave, 10MHz pulse, and 1PPS. MSD-295 can be disciplined from the internal GNSS receiver to get a more accurate UTC scale.
