Frequency Referencing, Calibration, Standards Lab, Production Test for
Oscillator Manufacturers
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.
