connector, this signal is used as the external reference source and “Ext
Ref” is displayed in the status bar of the user interface. When the external
reference is lost, transfinite or not connected, the instrument swithes to
its internal reference source automatically and “Ext Ref” on the screen
disappears.
 The [10MHz IN] and [10MHz OUT] connectors are usually used to
build synchronization among multiple instruments.
6. 10MHz OUT
DSA800 can use internal or external reference source.
 When internal reference source is used, the [10MHz OUT] connector
can output a 10 MHz clock signal generated by the analyzer. This signal
can be used to synchronize other instruments.
 The [10MHz OUT] and [10MHz IN] connectors are usually used to
build synchronization among multiple instruments.
7. TRIGGER IN
In external trigger mode, the connector receives an external trigger signal
through a BNC cable.
8. LAN Interface
Through this interface, the analyzer can be connected to your local network
for remote control. An integrated testing system can be built quickly, as the
analyzer conforms to LXI Core 2011 Device instrument standards.
9. USB Device Interface
The analyzer can serve as a “slave” device to connect external USB devices.
Through this interface, a PictBridge printer can be connected to print screen
image or a PC can be connected to control DSA800 remotely through
programming or PC software.
