Some units permitted users to connect A different oscillator, which could then be calibrated by comparing it on the oscillator which was section locked to WWVB [71]. The uncertainty of the WWVB disciplined oscillator was connected to the WWVB sign top quality, which meant that it had been frequently a purpose on the receiver’s length with the transmitter. Nonetheless, a frequency uncertainty of a lot less than one × 10−eleven could generally be acquired with in the future of averaging in most aspects of The usa.

Determine 15 is really a photograph of David Andrews and Robert Oase of NBS tuning the WWVB antenna to resonance about two weeks following the station went within the air. Equipment was later on mounted that tuned the antenna mechanically.
