Glossary Item Box

Gets or sets a value indicating whether the optional frequency reference (option B7E) is enabled.

Syntax

Visual Basic (Declaration) 
Public Overridable Property OptionalFrequencyReference As Boolean
C# 
public virtual bool OptionalFrequencyReference {get; set;}
C++/CLI 
public:
virtual property bool OptionalFrequencyReference {
   bool get();
   void set (    bool value);
}

Remarks

If Optional Frequency Reference (B7E) is False (default), connect the 10 MHz external reference signal directly to the 10 MHz Ref In connector near the bottom of the ESA rear panel. The close-in phase noise specs for the ESA are much better in this mode of operation. In this mode the ESA will also auto-detect the presence of the external reference signal and switch between internal and external automatically. The external reference state will be displayed in the 89600 display.

If Optional Frequency Reference (B7E) is True, you can set the external reference frequency from 1 MHz to 30 MHz. The default is 10 MHz. Connect the external reference signal to the Ext Ref In connector.Connect a short BNC cable from the 10 MHz Out connector to the 10 MHZ REF IN connector.
