Type 31 (Hail Spectrometer)
SEA Model 300
Type 31 (Hail Spectrometer)
Description
This acquisition type is used to acquire the hail spectral data from the Hail interface card. This
single slot interface adapter card has fifteen sixteen bit counter channels and twenty four single bit
events. This acquisition routine acquires the fifteen counter channel data.

Parameters
This routine uses the first two parameters to control the reset mode for each counter. As shown
above, each counter is controlled by a single bit in parameter one or two. If the control bit for a
counter is zero, the counter will be reset to zero each time the counter value is acquired. The acquired
count will represent the number of counts that occurred since the last acquisition. If the control bit
for a counter is a one, the counter will not be reset during data acquisition. The count will then
represent the total number of counts that have occurred since the system was started. Their control
bits are assigned as follows:
Data Size
This routine acquires thirty bytes of data for each sample and 30 bytes should be allocated for
each sample.
