13.3 System Settings
13.3.1 Language
The signal generator supports Chinese and English menu, and provides corresponding
help information, prompt information and interface display.
Press [Utility] > Language softkey to select the desired language. When "Chinese" or
"English" is selected, the menu, help message, prompt message, and interface are
displayed in Chinese or English, respectively.
The language is not changed when the [P] key is pressed to restore the default settings.
13.3.2 Clock Source
The instrument provides an internal 10MHz clock source and can receive the external
clock source from the [10MHz In/Out] connector at the real panel. It can also output the
internal clock source from the [10MHz In/Out] connector for other devices.
Press Utility > Clock Src softkey 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 [10MHz In/Out] connector at the real panel. If no valid
clock source is detected, the prompt message "No valid 10MHz External Clock is
detected" would be displayed and the clock source would be switched to "Internal".
Users can also synchronize two or more instruments by setting the clock source. When
two instruments are synchronized, the SYNC of phase cannot be used. The SYNC of
phase can only be used to adjust the phase relation between two output channels of the
same instrument and cannot be used to change the phase relation between the output
channels of two instruments. Users can change the phase relation between two
instruments by change the "Start Phase" of each channel.
Sync methods for two or more instruments:
⚫
Synchronization between two instruments:
Connect the 10MHz In/Out connector of Generator A (set the clock source to
"Internal") to the 10MHz In/Out connector of Generator B (set the clock source to
"External") and set the output frequencies of the two instruments as a same value
to realize the synchronization between the two instruments.
⚫
Synchronization among multi-instruments:
Divide the 10MHz clock source of a generator (set the clock source to "Internal")
into multiple paths; then, connect them to the 10MHz In/Out connectors of the
