*STB?
Query the Status Byte summary register. The *STB? command is similar to a
serial poll but it is processed like any other instrument commands.
The *STB? command returns the same result as a serial poll but the “Request
Service” bit (bit 6) is not cleared if a serial poll has occurred.
*WAI
Instruct the power supply to wait for all pending operations to complete before
executing any additional commands over the interface.
The *WAI command is used only in the triggered mode.
