binning times are 50 x 2
standard deviations) will be selected and displayed. In automatic binning mode, the Binning

(3) PCH
In PCH panel the binning time used for the photo
counting histogram can be selected.
• Click on the PCH tab to open the PCH panel
(Fig. 293).
You can either check the Automatic check-box, in
which case 32 different binning times will be used,
or you can de-activate the check box and enter a
number of a constant binning time (in µs) in the
Binning display window. You can either type in
values or use the arrows. Units are displayed at the
right of the display box. The default value of 10 µs
can be selected by pressing the 10 button.
(4) Dust filter
The Dust filter panel allows you to activate an
electronic dust filter that will be active in operation
during the measurement. You can define a
threshold in the Count rate intensity that, if
exceeded, will lead to a removal of the
corresponding count
correlation analysis (Fig. 375).
• Click on the Dust filter tab to open the Dust
filter panel (Fig. 294).
• Switch on or off the dust filter by ticking/
unticking the check box.
• A threshold in % is set by typing in a value into
or by using the arrows of the Deviation to
erase peak in Count rate display window. All
measurement points within a binned count rate
time window having a deviation of more than
the specified value from the average count rate
will be cut out and not used for the correlation
analysis (Fig. 295). The default value of 10 %
can be activated by pressing the 10 button.
