Operating Basics
Reference clock
The instrument can use an internal or external clock reference signal. When
the external clock reference input is activated, the rear panel Ext Ref Input
connector is used as the input for an external reference signal. The instrument is
synchronized by this signal.
The following procedure shows you how to set up the instrument to use an
external signal. Use of the internal signal does not require a connection to the
rear-panel input.
1.
Connect a reference
signal from a signal
source to the Ext Ref
Input connector on
the rear panel of the
AFG2021.
2.
Push the front-panel
Utility button.
3.
Push the System bezel
button.
4.
Push the Clock Ref bezel
button to toggle between
Internal and External.
