Considerations for the Phase Noise Without Using
a PLL Measurement
When loading a Test File from the Mass Storage Media, it is possible for
the Source Control Diagram to be configured incorrectly. If the Source
Control Diagram contained in a Test File that is being loaded specifies an
instrument that is not listed in the current System Configuration Table,
the HP 3048A will not be able to include the specified instrument in
the Source Control Diagram. Instead, the HP 3048A will specify the
instrument that is currently listed in the System Configuration Diagram,
or if an appropriate instrument is not listed, the Users Source specification
will be selected. {The System Configuration Table is not stored with the
Test File.)
Changing the Measurement Type can change the Source Control Diagram
as well as other Measurement Definitions. It is recommended that
you verify all Measurement Definition screens after selecting a new
Measurement Type.
