SCH100 series key features ? double-oven performance in a single-oven design ? unmatched wide temperature range stability ? sc-cut resonator ? temperature stability as low as 0.2 ppb common applicatons ? test instrumentaton ? satcom terminals ? broadcast reference standard ? military weapon/communicaton systems sofware compensated ocxo doc. #: SCH100-3p-ss rev: - functonal descripton through the implementaton of esterline research and design's new patent-pending m-sac technology, the new sch series of sofware-compensated ocxos is able to provide unparalleled temperature performance over the industrial temperature range and beyond. in additon, no other device on the market can ofer a comparable performance rato of temperature stability to input power. unlike traditonal ocxo products, sch-series ocxos are compensated for trim efect to ensure that temperature stability performance is maintained as the frequency is adjusted to correct for drif over tme (aging). the sch-series of ocxos also enjoys a higher immunity to orientaton and airfow efects, as compared to other contemporary ocxo designs. the standard co8, or euro package makes the sch-series ocxo ideal for upgrading existng applicatons to provide improved temperature stability or to expand the applicatons operatonal temperature range. p
