- | <del>HP5335A</del> HP5334A is measuring time from TrueTime XLi 1PPS to CSAC 1PPS (which is not time aligned to the clock 1PPS, but should track it 1:1). | + | |

- | The unwrapped TIC data is really just a simple remapping of [0,1] to [-0.5, 0.5]. | + | |

- | Temperature measurements from Acromag 965EN. "Clock" channel thermocouple is about 6 inches from the PCB. | + | |
