5.6.1 Sample column
In the “sample” column there is simply the index of the value read out from the FIFO (registers:
data_range). In this example we have 97 samples, corresponding to a value of 0x30 (in decimals:
48) of window length (see sw_start and sw_length registers).
5.6.2 Raw data column
Here we have the data as read out from the FIFO. Maxima and minima are highlighted. Only the
data in this column and the analysis data (see 5.5) are read out from AVM16.
5.6.3 Time column
Here we have the time at which the corresponding raw data value was sampled. This values were
not read out from the ADC, they were added manually basing on the “window start time” value.
The window start time is part of the data analysis and can be read out from the FIFO after the raw
data block, if raw data are present, or directly (see 5.5).
5.6.4 Hex column
This column is a repetition of the raw data column, with background colours indicating for which
parameter calculation (integral, average…) the data are used.
5.6.5 Dec column
This colums translates the values of the hex column into decimals, so that we can easily verify the
calculations made by the FPGA.
5.6.6 Absolute column
Here there are the same values as in the dec column, pedestal subtracted. The pedestal is the
“mean level” value from the data analysis (see 5.5), in this example it is 0x770, i.e. 1904 in
decimals.
