of the SE to any value between 0 and 30. The address can only be set from the front panel. The
address is stored in non-volatile memory and does not change when the power has been off or
after a remote reset.
 The address is set to 8 when the instrument is shipped from the factory.
8.3 Interface Functions

8.4 USB/RS-232 / GPIB Interface Command List
Echo and Response Considerations
USB/RS-232 Responses
The USB/RS-232 bus will automatically send any response back to the controller's input buffer.
GPIB Queries and Responses
The SE GPIB bus will not send any data to the controller without being queried. A GPIB read
command must be sent after a command string to retrieve any data from a query command (?).
