5 Common (*) Commands
selected and a common command is received by the instrument, the
instrument remains in the selected subsystem. For example, if the program
message ":ACQuire:TYPE AVERage; *CLS; COUNt 256" is received by the
instrument, the instrument sets the acquire type, then clears the status
information and sets the average count.
In contrast, if a root level command or some other subsystem command is
within the program message, you must re- enter the original subsystem
after the command. For example, the program message ":ACQuire:TYPE
AVERage; :AUToscale; :ACQuire:COUNt 256" sets the acquire type,
completes the autoscale, then sets the acquire count. In this example,
:ACQuire must be sent again after the :AUToscale command in order to
re- enter the ACQuire subsystem and set the count.
Each of the status registers has an enable (mask) register. By setting the bits in the enable
register, you can select the status information you want to use.
