Pulse Height Spectroscopical Measurements
be adjusted such that a shift of the spectroscopical filter of 100ns forward or backward will
not change the result. This modification is also very close connected to the decay time
constant of the preamplifier and therefore there is only one adjustment parameter which
adjusts both for pole zero and jitter.
Misadjustments will cause characteristic deformations of the peak shape as shown in
Figure 20.

Left: Correct PZC setting and Jitter compensation.
Right: PCZ=0, no Jitter compensation, the jitter error gives a rectangular
distribution.
