[:SENSe]:ROSCillator:SOURce:AUTO <Boolean>
Sets or queries the state of the auto-specifying reference timebase. With this on, the
counter automatically choose the external reference signal as the reference timebase
when a valid signal is present at the Ref In connector on the rear panel. When an invalid
signal is present at this connector, the internal timebase is used.
Return
A single ASCII-encoded byte. 0 means Off and 1 means ON.

This will be set back to its default, which is ON, after the counter has been turned off
