190 WinView/32 Manual Version 2.4.M
Sequential Mode
If Sequential is selected, the Sequential Pulsing setup dialog box will appear as shown in
Figure 171. In the Sequential Pulsing mode, the Pulse Width and Pulse Delay do not
remain constant but change either linearly (
Fixed
) or exponentially as the measurement
progresses.
Fixed
is suited to sweeping over a time interval to locate and recover and
event that takes place at the same time with each iteration.
Exponential
is well suited
to fluorescence decay experiments where the effect under study changes rapidly at the
start of an experiment and then slower and slower, following a logarithmic curve, as the
experiment progresses. See page 339 for a detailed discussion of the Sequential Pulsing
setup parameters. In any case, if the measurement is to be done in the sequential pulsing
mode, set the pulsing parameters as appropriate for your intended measurement and click
on
OK
. The Pulse Sequence Setup dialog box will close and you return to the PTG
window.

button. This writes all of the parameter values to the
PTG.
Note:
The PTG can also be controlled interactively as data is being collected. For
more information, see the discussion of this feature starting on page 366.
