Ultra Low Noise, Rubidium Frequency Standard.
A10-M
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.

1pps-Locking-Modules
This is a module to control an OCXO or Rubidium oscillator with 1PPS from a GPS receiver. The Quartzlock A6-1PPS uses a 3 state Kalman filter algorithm to measure & correct the frequency offset of the oscillator with respect to the 1PPS input. Time-tagged input 1PPS to 200ps resolution & <1ns jitter. Analog interpolator is self calibrating. Interface to GPS decodes messages & extracts relevant info. i.e. time correction data for 1PPS output, this has AVAR of the Rb or OCXO i.e. 5 x 10-12/s & <100ps RMS jitter. The output is steered to time coincidence with GPS time/UTC to 1ns resolution. Holdover initiated by 1PPS fail or data from GPS RX that 1PPS is inaccurate. During holdover, measured frequency offset & drift steer the oscillator & 1PPS is still available.

Distribution Amplifiers
The Quartzlock range of distribution amplifiers are intended for use when multiple outputs from a single frequency standard/generator are required. This may be encountered in engineering labs, national standards labs, research and development, calibration labs and production. This is vital for the distribution of signals from other precision frequency standards like Hydrogen Masers, Cesium oscillators.
