2. USB Device Interface
The analyzer can serve as a “slave” device to connect external USB devices. Through this
interface, a PC can be connected to control the analyzer remotely through programming or PC
software.
3. LAN Interface
Through this interface, the analyzer can be connected to your local network for remote control.
4. REF IN 10MHz
The analyzer can use internal or external reference source.
When a 10 MHz external clock signal is received through the [10MHz IN] 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 switches 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.
5. REF OUT 10MHz
The analyzer 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.
6. Trigger in
In external trigger mode, the connector receives an external trigger signal through a BNC cable.
7. Security Lock Hole
If needed, you can use a security lock (buy it yourself) to lock the analyzer to a desired location.
8. AC Power Supply and Fuse
The analyzer accepts 100-240V, 50/60/440Hz AC power supply. Please use the power cord
provided as accessories to connect the instrument. Before power on, make sure the spectrum
analyzer is protected by fuse.
