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.

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.
