Keithley 2016 - Figure 5-7 Measurement Event Enable Register; Figure 5-8 Questionable Event Enable Register

SCPI Command Reference 5-57
Each event enable register is used as a mask for events (see [:EVENt] for
descriptions of events). When a bit in an event enable register is cleared (0),
the corresponding bit in the event register is masked and thus, cannot set the
corresponding summary bit of the next register set in the status structure.
Conversely, when a bit in an event enable register is set (1), the
corresponding bit in the event register is unmasked. When the unmasked bit
in the event register sets, the summary bit of the next register set in the status
structure will set.
The decimal weighting of the bits for each event enable register are included
in Figure 5-7, Figure 5-8, and Figure 5-9. The sum of the decimal weights of
the bits that you wish to set is sent as the parameter (<NRf>) for the
appropriate :ENABle command. For example, to set the BFL and RAV bits
of the Measurement Event Enable Register, send the following command:
:stat:meas:enab 544
where; BFL (bit B9) = Decimal = 512
RAV (bit B5) = Decimal = 32
<NRf> = 544
