Quartzlock has built many customer specific products under the above heading.

Some examples that employ Quartzlock core technologies are;

  1. AIS, Air Interface Simulator for 1GHz GSM network quality analysis and simulation.
  2. RADEX, an aerospace antenna test site 400MHz RF switch and signal conditioning system with software.
  3. RF Switch for single source, multiple outputs 24 per card. Multiple cards. Low loss, high Isolation @ up to 10GHz complete with RS232 control.
  4. MBTS, Maser Based Timing System. To distribute Hydrogen Maser reference 1MHz, 5MHz, 10MHz and 100MHz signals of highest available stability to multiple users. Monitor both Maser physics and all vital functions, locally and remotely. Display locally and remotely performance verification data. Have station clock displays and 100% carrier phase tracking GPS time synchronisation for the Maser. High reliability redundant power supplies, battery backup and very low noise grounding / monitoring. Environmental monitoring, recording and plotting of multiple parameters.
  5. Galileo Test Solution, GNS IOV SV Space Qualified Passive Hydrogen Maser (SPHM) and Space Qualified Rubidium Atomic Frequency Standard (RAFS) test facility using Hydrogen Maser and very high quality frequency conversion and distribution with best available frequency and phase metrology analyser.
  6. Low Noise Rubidium reference source with multiple distribution system for EGNOS.
  7. Multiple Rubidium reference for Police Radio transmitter chain in a quasi synch system with very long life and end of life support.
  8. High Power 150MHz and 450MHz RF Sources with modulation for defence related Plasma research.
  9. HF SSB transmitter output analyser. Power, Modulation, VSWR, SSB envelope display etc.
Radiotelephone test system. VHF, UHF, power, modulation AM, PM, FM and Frequency of TX, CTCSS, Synthesized Signal Generator with AM, PM, FM, CTCSS den-code etc.
