5.1.5. ADC Settings dialog
Clicking in the Settings overview the
ADC Settings...
button opens the ADC Settings and Presets
dialog box. Here parameters like presets, range parameters, coincidence time, etc. can be set.
If expanded ADC ports are enabled in the MPA4.INI file, additional controls for
Port width
and
Binwidth
appear as shown right in Fig. 5.8.
In the edit field
Range
the length of the spectrum can be chosen in binary steps.
Set All
sets the
range for all ADCs, otherwise each ADC can be selected from the drop down list and changed
seperately. If the checkbox
ROIpreset
is marked, the measurement will be stopped after
acquiring more events than specified in the corresponding edit field. The events are counted only
if they are within the
ROI
6
limits, i.e. >= the lower limit and < the upper limit. Another possibility is
to acquire data for a given run time via the
RTimepreset
or a given live time via the
LTimepreset
. A measurement will be stopped if the corresponding checkbox is marked. The
width of the coincidence window can be set between 0.15 and 3276
µ
sec in steps of 50 nsec by
entering the number or using the scroll bar. The
Data Ready Timeout
can be set within the same
limits. It must be large enough to cover the ADC conversion time.
OK
takes all settings.
Cancel
cancels all changes. Pressing
Save Settings
writes all settings into the file
MPA4A.SET
resp. the
entered setup name.
