The phase noise for a standard Rubidium source is not acceptable for some applications and we offer a low noise Rubidium frequency reference that includes a low noise OCXO that is locked to the Rubidium source (NR2110-R/O). To further enhance long-term stability, GNSS locking of the Rubidium source is added. The stability of Rubidium, the low phase noise of an OCXO and the long-term stability of GNSS locking. The dual time base adds a second GNSS receiver that provides master timing for an embedded frequency counter to monitor the Rubidium reference. Measured performance is displayed locally or is acessisble over the Internet.
