10.3 System Settings
10.3.1 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.
10.3.2 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 Source
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 other generators (set the
clock source to "External) respectively. Finally, set the output frequencies of all the
generators as a same value to realize the synchronization among multi-instruments.
