Events
In CPRI RE test mode the R&S
EX-IQ-BOX acts as a CPRI REC (master). As defined in
the CPRI standard specification, the CPRI REC provides the generation of Layer 1 mes-
sages. In this section, you can simulate some events. Use this function to see how the
DUT responds to these events.
SDI
Activate the SDI (
S
ervice Access Point
D
efect
I
ndication) defect indicator. This function
intentionally provokes an SDI event, in order to examine whether the DUT evaluates it.
In realtime applications, the function detects whether an SAP (

defective or is not working properly.
