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.
