R&S PR100 User Manual
ENABle bit = 0: the associated EVENt bit does not contribute to the
summary bit
ENABle bit = 1: if the associated EVENT bit is "1", the summary bit is
set to "1" as well.
This section can be written into and read by the user in any way. Its contents
is not changed during reading.
Summary bit
As indicated above, the summary bit is obtained from the EVENt and ENABle
section for each register. The result is then entered into a bit of the CONDition
section of the higher-order register. The device automatically generates the
summary bit for each register. Thus an event, e.g. a PLL that has not locked,
can lead to a service request through all the hierarchy levels.
Note
The service request enable register SRE defined in IEEE 488.2 can be taken
as ENABle section of the STB if the STB is structured according to SCPI. By
analogy, the ESE can be taken as the ENABle section of the ESR.
