This is a mean figure so I would guess they buy a whole lot and grade them, could be 120dB is only like 1 out of 100 which justifies the higher price. I purchased this OCXO (oven controlled crystal oscillator) for the Fluke 6060B when I wasn't sure if I could fix its faulty OCXO, turns out I could fix it, so I now have this one sitting around as. An OCXO (or Oven Controlled Crystal Oscillator) is near the top of the food-chain when it comes to quartz based frequency control devices, superseded only by the mighty DOCXO or Double Oven! An OCXO is a temperature-controlled device that maintains a quartz crystal's constant operating temperature. OCXO: Frequency Range (MHz) Output: Supply: Temp Stability 0 to 70°C (ppb) Temp Stability – 40 to 85°C (ppb) Aging (ppb) day: Aging (ppb) year: Phase Noise at 10 Hz: Phase Noise Floor: DX-040 50. USED (8663-XS 10 MHz Double Oven OCXO Double sinewave OSCILLOQUARTZ 8663-XS 10MHZ ). This will be in a box, probably metal, and I'm thinking that 4.

Taitien’s main products include a wide range of quartz crystals, oscillators, VCXOs, TCXOs, OCXOs, precision crystals, and thickness monitor crystals. Oven: Preheat oven to 450°F. The standard CO8, or "EURO" package makes the SCH-series OCXO ideal for upgrading existing applications to provide improved temperature stability or to expand the application's operational temperature range. temperature - up to ±1x10-10; • Available as RoHS. examples of Stratum 2 clocks are Rubidium Standards and Double Oven OCXO's. 'View in the areas of Business & Industrial,Consumer Electronics for sale by by fluke. It has been found that the present processor compensated OCXO 10 can achieve double oven crystal oscillator temperature stability without double oven labor costs. These new models come in a low profile 10. If stability requirements are too stringent to be met by a basic crystal oscillator or TCXO, the crystal and. The instrument comes with a double-oven OCXO timebase that has phase noise of less than -125 dBc/Hz at 10 Hz offset. The RoHS-compliant oscillator was designed to meet the frequency stability requirements of CDMA and UMTS applications. The IZT R3600 contains a high stable oven controlled crystal oscillator (OCXO). The type used in CARABAS-II and LORA is equipped with the optional double oven for the 10 MHz oscillator with a 24 h accuracy of 1* 10-12 when connected and locked to the. It is in compliance with European energy-saving standard Lot 6. examples of Stratum 2 clocks are Rubidium Standards and Double Oven OCXO’s. The internal OCXO can be locked to an external 10 MHz reference by connecting the reference to the 10MHZ_IN input. This unit also has a double oven OCXO. Stratum 3 is defined as a clock system which tracks an input as in Stratum 2, but over a wider range. The oscillator in conjunction with the EpsilTimeTM smart predictive slaving algorithm mitigates the effects of inherent GPS noise and complies to the most stringent. pdf Thunderbolt Monitor_Tboltmon.
