Description
These commands are used to set the contents of the event enable registers (see Figure 15-7,
Figure 15-8, and Figure 15-9). An :ENABle command is sent with the decimal equivalent of the
binary value that determines the desired state (0 or 1) of each bit in the appropriate register.
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 correspond-
ing 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 15-7,
Figure 15-8, and Figure 15-9. 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
