Remote Operation
The U3606B is shipped with both a GPIB (IEEE- 488)
interface and a USB 2.0 interface on the rear panel. Only
one interface can be enabled at a time. The GPIB interface
is selected by default when the U3606B is shipped from the
factory.
The remote interface can be selected from the front- panel
only.
• The interface selection is stored in the non- volatile
memory, and does not change when power is turned off
or after a remote interface reset.
• If you select the GPIB interface, you must select a unique
address for the U3606B. The current address for the
U3606B is displayed on the lower secondary display in
the Utility menu.
• You can select between two USB class: USB- TMC or
USB- CDC. USB- TMC is the default USB 2.0 full- speed
communication protocol interface that is compliant to
USB standards, while USB- CDC is simulates a serial
communication (RS- 232) interface at the PC through the
physical USB port connection.
The instrument automatically enters the remote state
whenever SCPI commands are received over the GPIB or
USB interface. The Rmt annunciator is illuminated and the
front panel keys are locked when in the remote state. Press
[Local] to return the U3606B to front panel operation.
