STATUS REGISTERS
Status registers store a record of events and conditions that occur inside the DSO. Some of the events
recorded are: New data has been acquired; Processing has completed; Hardcopy has completed; An error has
occurred; etc. The programmer can use the registers to sense the condition of the instrument by polling them
until the desired status bit has been set. A status register can be polled by querying its associated remote
command (e.g., *STB, INR?, *ESR, etc.). Alternatively, with GPIB, the scope can request service from the
controller by using the mask registers to select the events of interest.
The following diagram (Figure 1) shows the steps necessary to acquire data using the status registers for
synchronization.
