Using *OPC? synchronization is the simplest approach. It requires
no status handling or loops. However, you must set the controller

Messages
Tables 3--3 through 3--9 list all the programming interface messages
the oscilloscope generates in response to c ommands and queries.
Each message is the result of an event. Each type of event sets a
specific bit in the SESR and is controlled by the equivalent bit in
the DESER. Thus, each message is associated with a specific SESR
bit. In the message tables that follow, the associated SESR bit is
specified in the table title, with exceptions noted with the error
message text.
Table 3--3 shows the messages when the system has no event s or
status to report. These have no associated SESR bit.
Table 3- 3: No event messages
