The introduction of zero-dead-time counters removed the need for this analysis. A zero-dead-time counter has the property that the stop event of one measurement is also being used as the start event of the following event. Such counters create a series of event and time timestamp pairs, one for each channel spaced by the time-base.
1940s – Precision measurement instruments including radio frequency analyzers and Geiger counters. Type 2401, a vacuum tube voltmeter, was the first instrument produced. Type 4301, launched in 1943, was the world's first charge accelerometer, while Type 2301 marked the success of the company in 1949. Since then it has been updated a number of ...
Narrow pulses can offer good resolution, but they have high frequency signal components that are attenuated in long cables. The shape of the pulse is often a half cycle sinusoid. [2] For longer cables, wider pulse widths are used. Fast rise time steps are also used.
is the motor constant [1] (sometimes, motor size constant).In SI units, the motor constant is expressed in newton metres per square root watt (/): = where is the motor torque (SI unit: newton–metre)

The 41.8% point is the wavelength-frequency-neutral peak (i.e. the peak in power per unit change in logarithm of wavelength or frequency). These are the points at which the respective Planck-law functions 1 / λ 5 , ν 3 and ν 2 / λ 2 , respectively, divided by exp ( hν / k B T ) − 1 attain their maxima.
