The Quartzlock A8 series GPS T&F reference does use a down-convertor mounted under the antenna. Contact Nick Law at [email protected] for details. We will service any unit, however old (we have never said “no longer supported” in 45 years) The series were A8-B (bench instrument GPS OCXO) A8-RT, (1U rack-mount GPS OCXO) & A8-M (2U rack-mount, metrology unit with high stab rubidium oscillator) disciplined by the 100% carrier phase tracking RX. Most problems were, as common with many GPS, poor antenna position or cable/connector assembly, where the cable had been extended or water ingress to down convertor (bike pump action) if connectors not sealed, we supplied real of self amalgamating tape with each unit. The cable only carries 90MHz & 10.23MHz with dc supply from the A8 GPS RX antenna input connector. uP now obsolete, so the line was replaced by current E8-X/E8000/E8010-Rb. E8-X board level OEM units £295. Can replace more expensive A8(£5k….15k) Rb have 3yr warranty. Earlier manuals will be on www.quartzlock.com “soon”. 2nd users will still have service.
