tus 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 Figures 3-28
through 3-33. The sum of the decimal weights of the bits that you wish to set is sent as the pa-
rameter (<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
