LOW PHASE NOISE, SPACE LEVEL OCXO

3.3 to 15Vdc - 1MHz to 125MHz

Q-TECH

CORPORATION

QPDS-0008 (Revision B, April 2013 )(ECO# 10835)

Description

Q-Tech’s High Stability Oven Controlled Crystal Oscillator

(OCXO) is a high reliability signal generator that provides Sine

wave or HCMOS output. The OCXO is designed to be used in

Aerospace applications.

It is designed to withstand radiation level up to 100kRad (*)

(total dose), high shock and vibration. The OCXO has very low

phase noise. Low G-Sensitivity SC-Cut Crystal utilized in the

design guarantees 1PPB/G or better. The reliable construction

of this design qualifies it for stringent environmental

applications.

(*) Please contact factory for higher level of radiation

hardness.

LOW PHASE NOISE, SPACE LEVEL OCXO Q-TECH 3.3 to 15Vdc - 1MHz to 125MHz CORPORATION Phase Noise and Phase Jitter Integration Phase noise is measured in the frequency domain, and is expressed as a ratio of signal power to noise power measured in a 1Hz bandwidth at an offset frequency from the carrier, e.g. 10Hz, 100Hz, 1kHz, 10kHz, 100kHz, etc. Phase noise measurement is made with an Agilent E5052A Signal Source Analyzer (SSA) with built-in outstanding low-noise DC power supply source.
