1. Handle
Pull up the handle vertically for easy carrying of the instrument. When you do not need the handle,
press it down.
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 SPA-900 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
SPA-900 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.
