When a mapped event is programmed to clear bits, the bit in the condition register is set to
0
when
the event is detected.
If the event is set to zero (
0
), the bit is never set.
See
(on page B-9) for information about event numbers.
Example
status.questionable.setmap(0, 4917, 4918)
When event 4917 (the buffer is 0% filled) occurs, bit 0 is set in the condition register and the event register of
the Questionable Event Register. When event 4918 (buffer is 100% filled) occurs, bit 0 in the condition register
is cleared.

SRQEnableRegister
The status of the service request (SRQ) enable register; a zero
(0) indicates no bits set (also send 0 to clear all bits); other values
indicate various bit settings (0 to 255)
Details
This command sets or clears the individual bits of the Status Request Enable Register.
The Status Request Enable Register is cleared when power is cycled or when a parameter value of 0
is sent with this command.
The instrument returns a decimal value that corresponds to the binary-weighted sum of all bits set in
the register.
