  • A very high stability LOW NOISE 10MHz Rubidium Reference, primarily for production test of quartz oscillators and RF instrumentation frequency referencing. This industry standard 2U rack-mount instrument has a long heritage and ongoing production life for this latest 2009 version that features RS232 monitoring and control of the DPLL, locking the Ultra Low Noise OCXO to the Rubidium. Damping and Bandwidth is controlled by integrator digital gain, proportional digital gain, pre-filter order and subsample rate. Eight values of user selected bandwidth are available.
  • Phase noise to -115dBc/Hz @ 1Hz offset & noise floor of -173dBc/Hz with excellent short term stability at E x 10-13/s. Frequency accuracy of E-10 with bi-annual calibration or E-13 with GPS locking input option fitted (with QL E8-Y/E8000 GPS T&F ref) This industry leading product can offer 100MHz outputs with circa -180dBc/Hz noise floor. Ultra Low Noise multiple outputs are available. The internal distribution amplifier features -140dBc/Hz @1Hz offset, >110dB isolation @ 10MHz and 90dB @ 100MHz.
