If you move your gear to someplace strange, you have to consider warm up time and changes in temperature and local magnetic field and who knows what else. You can calibrate it without help from a cesium. Just use GPS and wait long enough for the short term noise to be insignificant. One approach would be to use the 10 MHz from your Efratom FRK to drive the clock on one of tvb's picPETs and feed the PPS from your GPS to its event input. http://www.leapsecond.com/pic/picpet.htm Then just collect the data for a day or week. -- These are my opinions, not necessarily my employer's.
