Isotope Edit...allows the user to edit isotope data, add to and delete from library.
Erase
The contents of the active buffer (both the displayed and card buffers) can be reset to zero by selecting Erase. Live Time
and Real Time status is also reset to zero. This action cannot be undone. Erasure may also be performed by clicking on
the Erase Button when acquisition is stopped.
Undo
The effects of Background Subtraction or Smoothing may be removed and the original spectra restored to the display
window by selecting Undo.
Copy
The contents of the current window are copied into the Windows Paste Buffer. If a spectral graph is displayed, the buffer
will contain a graphic image which may be pasted into a document of your choosing.
If the window is displaying a Data Report or Peak Report, that text is placed into the Paste Buffer and may be inserted into
a document of your choosing (such as a word-processing file). Once pasted, the text can be manipulated and formatted to
suit your needs.
Mode
Start - Start data acquisition using the currently defined settings for the currently defined mode.
Stop - Stop data acquisition.
PHA (Pulse Height Analysis) - The normal operating mode for collecting sample emission spectra. The amplitude of
each detector pulse is measured by the ADC and stored as an amplitude (energy) spectrum. By selecting the appropriate
mode, the signal may be routed through or made to bypass some parts of the internal electronics.
MCS (Multichannel Scaling) - This mode is used for measuring time related phenomena such as half-life decay or single
photon counting. Incoming events are counted for specific predetermined times (dwell time) and stored in sequential
memory locations. The card is supplied with the internal preamplifier/amplifier enabled for counting events directly from a
NaI(Tl) detector. When using an external signal, it will be necessary to select 'MCS External' from the menu.
