:ENABle? Query enable register
These commands are used to set the contents of the event enable registers (see Figures 3-27
through 3-32). 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 sta-
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 3-27
through 3-32. 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
RAV (bit B5) = Decimal
<NRf> =
PRINT #1, "output 16; :stat:oper:enab 514; enab?"
PRINT #1, "enter 16"
