Quartzlock’s Journey1964 Saw the first Clive Green & Roger Davis production-run products in RF & microwave frequency “down convertors” and RF VHFsources. These were followed by CW & AM radio transmitters, 600 Watt HF SSB Passive Grid Linear Amplifiers with exceptionally low,cross and inter-modulation products.1970 High power VHF & UHF RF sources for MoD plasma research. RF Test equipment. An SSB, AM, CW TX 1000W single box testsolution with SSB power measurement.1980 True RMS RF power meter with dynamic range from 10mW to 1000W (linear scale), Worlds First TTL Synthesized SignalGenerator (Peter Broadbent) helped keep UK Sonar ahead. A 100MHz Synthesized Signal Generator (Toby Holland under PB) Manual& Automatic modulation meters with phase mod capability. The most compact single portable 230V / 12V dc radiotelephone test set(John Lake, John Bloice, PB, CRG, Peter Ward and others)1990 Exploited early LF Off Air Frequency Standard design with rapid R&D to an industry standard product selling low 1,000’s (PB…Colin Desborough…Graham McCloud/Dr Cosmo Little)2000 Consolidating Rubidium Technology and joined the Hydrogen Maser radio-technology originators and world leaders IEMKvarz. Subsequently sold some 50 Active & Passive H Masers around the world with Quartzlock’s own A5 Ultra Low Noise DistributionAmplifiers & A6 Frequency Convertors. The Quartzlock A7-MX Signal Stability Analyzer production began (CL, WK) A5, A6, A7 earlyA10 Rb, A5000, A8 GPS line followed (Dr Wolfgang Klisch, Hadwin Kramer).2010 New A5000, E1000, E8000, E8010, E8-X, E8-Y, include new A6-CPS technology for low noise & clean technology. 1PPS timingmodule introduced.2012 The introduction of completely new sub-miniature Rb components & Rb instruments with Ultra Low Noise versions available. TheE10-MRX Rb is lowest cost & power, OCXO size with 150g mass. A NMI level E5 Signal Distribution Amplifier (replaces E5) is introduced.Radio telephone test set 1980 10mW–1000W RMS Power Meter Modulation meter 1975 World’s first TTL synthesized signal generator 1970sContact QuartzlockFor all enquiries please contact us via any of the methods below:Head Office & Maser Lab:Quartzlock UK Ltd‘Gothic’Plymouth RoadTotnes, DevonTQ9 5LH EnglandTelephone:+44 (0)1803 862062Facsimile:+44 (0)1803 867962Email:sales@quartzlock.comOr visit our website www.quartzlock.comThe Quartzlock logo is a registered trademark.
