Complications in Recording Spectra

The best possible case for recording an undistorted spectrum when the pulse is incident on the probe circuit is given by the sine function for the power distribution of the pulse. Complications beyond this include the frequency response of the probe in detecting the 

In addition to the effects from the probe there is the electronic deadtime, including pulse ringdown (100 ns), preamplifier recovery (800 ns), filter overdrive recovery (1 p.s) and ADC conversion droop (200 ns) (Hoult 1979). Magnetoacoustic ringing (up to 200 p.s) can be very significant if careful probe design (e.g. coil wire) is not considered. Samples that exhibit peizoelectric behaviour can lead to very long response times of up to 10 ms.
