Query :ENABle? Query enable register
Description These commands are used to set the contents of the event enable regis-
ters (see Figures 5-7, 5-8 and 5-9). 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 corresponding bit in the event register is unmasked. When the un
-
masked 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 in-
cluded in Figures 5-7, 5-8 and 5-9. The sum of the decimal weights of the
bits that you wish to set is sent as the parameter (<NRf>) for the appropri
-
ate :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
