Chapter 2 Front Panel Operations
Clock Source
DG2000 provides an internal 10MHz clock source and receives the external clock
source from the rear-panel [10MHz In/Out] connector. It can also output clock
source from the [10MHz In/Out] connector for other devices.
When the Shift key is illuminated, press Pulse/Utility → System Setting → Clk
Source to select "Internal" or "External". The default is "Internal". If "External" is
selected, the instrument will detect whether a valid external clock signal is input from
the rear-panel [10MHz Out/In] connector. If no valid clock source is detected, a
prompt message "No valid external clock is detected!" is displayed, and the clock
source will be switched to "Internal".
You can synchronize two or multiple instruments by setting the clock source. When
two instruments are synchronized, the "Align Phase" function cannot be used. It is
only applicable in adjusting the phase relations between two output channels of the
same instrument and cannot be used to change the phase relations between the
output channels of two instruments. Of course, you can change the phase relations
between two instruments by modifying the "Start Phase" of each output channel.
Sync methods for two or multiple instruments:
Synchronization between two instruments:
⚫
Connect the [10MHz In/Out] connector of Generator A ("Internal" clock) to
the [10MHz In/Out] connector of Generator B ("External" clock) and set the
output frequencies of A and B as the same value to realize synchronization
between two instruments.
Synchronization among multiple instruments:
⚫
Divide the 10MHz clock source of a Generator ("Internal" clock) into multiple
channels, and then connect them to the [10MHz In/Out] connectors of other
generators ("External" clock) respectively, and finally set the output frequencies
of all the generators as the same value to realize synchronization among
multiple instruments.
Beeper
When the beeper in DG2000 is enabled, a beep sound is generated when an error
occurs during front-panel operation, touch screen operation, or remote operation.
When the Shift key is illuminated, press Pulse/Utility → System Setting →
Beeper to select "On" or "Off". The default is "On".
