Description of the MCA527 Firmware Commands
Command name
CMD_QUERY_ENRICHMENT
Compatibility
Identical to the MCA166 command.
Execution right
Not necessary
Description
The command reads current dead time, real time and the integral of two ROIs. This is very useful
during a running measurement because in this way there is no need for transferring parts of the
spectrum data for calculating the ROI integrals itself. The name of the command refers to its original
usage. The command is, of course, usable for all applications that need this information.
