3.0 PERFORMANCE REQUIREMENTS

3.1 General Definition

The TCXO is a high reliability signal generator that provides a sine-wave output. The TCXO has been

designed to operate in a spaceflight environment with an expected lifetime in excess of 15 years.
Lifetime is defined as the sum of operational and storage environments.
