(symbol '&'). The results of all logical operations of this part are passed on to the sum
bit via an OR function (symbol '+').
ENABle-Bit = 0: the associated EVENt bit does not contribute to the sum bit
ENABle-Bit = 1: if the associated EVENT bit is "1", the sum bit is set to "1" as well.
This part can be written into and read by you at will. Its contents is not affected by
reading.
Sum bit
As indicated above, the sum bit is obtained from the EVENt and ENABle part for each
register. The result is then entered into a bit of the CONDition part of the higher-order
register.
The instrument automatically generates the sum bit for each register. Thus an event,
e.g. a PLL that has not locked, can lead to a service request throughout all levels of the
hierarchy.
The service request enable register SRE defined in IEEE 488.2 can be taken as
ENABle part of the STB if the STB is structured according to SCPI. By analogy, the
ESE can be taken as the ENABle part of the ESR.
