File System
Press System, More (1 of 3), More (2 of 3) to access the File System key. The

Free memory in units of megabyte (MB).
Reference
Press the Reference menu key to activate a menu which allows you to
select an external reference, or to deactivate a 10 MHz out signal on the
rear panel.
• Freq Ref - Allows you to select an external or an internal (the
default) reference. When toggled to Ext (external) you will set the
external reference frequency by entering a value between 1 and 30
MHz. When the instrument is locked to an external reference a
green Ext Ref indicator will appear in the annunciator bar.
NOTE External reference values are persistent. This means that the external
reference frequency you select will remain active until it is changed,
even if the instrument is turned off and on, or preset. If the frequency
you have input to the rear panel external frequency connector is not the
same as the external frequency value you have manually set, a red Ext
Ref error indicator and a red Unlock error indicator will appear in the
annunciator bar.
