WebApr 25, 2024 · Acquisition Time. The acquisition time (AT) is the time after the pulse for which the signal is detected. Because the FID is a decaying signal, there is not much point in acquiring the FID for longer than 3 x T 2 because at that point 95% of the signal will have decayed away into noise. Typical acquisition times in 1 H NMR experiments are 1 – 5 sec.

WebHigh precision time-of-flight (TOF) measurements in modern high-energy physics experiments have often a high demand to measure both pulse timing and pulse width at the same time.
