In its factory default mode, the signal generator can detect a valid reference signal at this
connector and automatically switch from internal to external reference operation. See
the Signal Generator” on page 40
. With Option 1ER (flexible reference input), you must explicitly
tell the signal generator the external reference frequency you wish to use; enter the information
through the front panel or over the remote interface.
