HP5335A HP5334A is measuring time from 'every other 1PPS' clock debug signal to XLI 1PPS out.
The unwrapped TIC data is really just a simple remapping of [0,1] to [-0.5, 0.5].
Temperature measurements from Acromag 965EN (loaner unit courtesy of WV7U. TNX!) “Clock” channel thermocouple is in the air about 2 inches from the 10 MHz crystal. “Window” channel thermocouple is leaning against the window (about 18 inches from the clock).
