10 MHz REF
Coaxial BNC connector used as an input or output for the 10 MHz reference clock signal.
The function of the 10 MHz REF connector depends on the Int. Reference or Ext. Reference setting in the
System menu:
 If Int. Reference is active, 10 MHz REF is used as an output connector for the 10 MHz internal
reference clock signal of the analyzer.
 If Ext. Reference is active, 10 MHz REF is used as an input connector for an external 10 MHz
reference clock signal. The external reference signal must meet the specifications of the data
sheet. The internal reference signal is synchronized to the external signal.
