reference is lost, transfinite, or not connected, the instrument switches to 
the internal reference automatically. At this time, the icon "Ext" in the status 
bar of the user interface disappears. 
  The [10MHz IN] and [10MHz OUT] connectors are usually used to 
realize synchronization among multiple instruments. 
Note: When you input or disconnect an external clock signal for the first time, 
the network will be reconfigured. 
6.  10MHz OUT 
RSA3000E can use the internal or external reference source. 
  When the 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 
realize synchronization among multiple instruments. 
7.  TRIGGER IN/OUT 
Indicates the input and output terminal of Ext Trigger2. You can press 
Input Output  Ext Trigger2 to set it to be the external trigger input 
interface; or use it to synchronize the trigger output interfaces of other test 
devices. 
8.  TRIGGER IN 
Indicates the input terminal of Ext Trigger1. The Ext Trigger1 signal is sent to the 
spectrum analyzer through a BNC cable. 
9.  LAN 
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. 
10. USB DEVICE 
The analyzer can serve as a "slave" device to connect to the external USB device. 
The analyzer can be connected to the PC through this interface. Then, the 
RSA3000E series spectrum analyzer can be controlled remotely through 
programming or the PC software. 
11. USB HOST 
The analyzer can serve as a "master" device to connect to the external USB 
device. The USB storage device, the keyboard, and the mouse can be connected 
to the instrument via the interface. 
12. HDMI 
The interface is used to connect to the display, enabling you to clearly observe 
the signal under test and its characteristics.
