| Abstract | Many calibration and testing laboratories now employ a Global Positioning System disciplined oscillator (GPSDO) as their primary standard * for frequency. GPSDOs have the advantage of being much less expensive than cesium oscillators, and serve as "self-calibrating" standards that should not require adjustment or calibration. This makes them an attractive choice for many laboratories. However, some of their performance characteristics make a GPSDO less suitable than a cesium oscillator for some applications. This paper explores the use of GPSDOs in calibration laboratories. It discusses how GPSDOs work, how measurement traceability can be established with a GPSDO, and how their performance can vary significantly from model to model. It also discusses possible GPSDO failure modes, and why a calibration laboratory must be able to verify whether or not a GPSDO is working properly. |
