Conversion Gain
— This sets the maximum channel number in the spectrum. If set to 16384, the energy scale
will be divided into 16384 channels. The conversion gain is entered in powers of 2 (e.g., 8192, 4096, 2048).
The up/down arrow buttons step through the valid settings.
●
Upper- and Lower-Level Discriminators
— The
Lower Level Disc
riminator sets the level of the lowest
amplitude pulse that will be stored. This level establishes a lower-level cutoff by channel number for ADC
conversions. The
Upper Level Disc
riminator sets the level of the highest amplitude pulse that will be stored.
This level establishes an upper-level cutoff by channel number for storage.
