• The maximum waveform period is 2.0 s. However, for 2D data,
because only one data point is generated per waveform period, the
effective maximum length of a waveform period depends on the data
collection rate (the rate at which Chromeleon collects digital data
points from the detector). The relationship is as follows:
• Multiple waveforms can be defined for a single run, provided they all
have the same cycle duration. Up to 15 waveform changes per run are
allowed.
• Each waveform can have only one integration interval.
• The integration interval generates one integrated data point per
waveform.
Chromeleon and Chromeleon Xpress provide several pre-programmed
waveforms (see Figure 2-28
).
