If the Timebase DAC value has been changed, but no Save operation performed before exiting this menu, a warning is provided to the user that they have not saved their setting: Timebase DAC Allows the technician the ability to adjust the 10 MHz reference (“timebase”).

  • Page 353: Corrections

    Service and Diagnostics Menus Service Key Descriptions Corrections The Corrections menu allows the technician to activate and deactivate specific amplitude correction sets. With this capability, the technician can determine if an anomaly is a result of raw hardware performance or incorrect correction data.
  • Page 354 Service and Diagnostics Menus Service Key Descriptions IF Flatness This function turns the corrections related to IF flatness On or Off. When IF Flatness is OFF, the Advisory Event “IF Flatness corrections OFF” will be displayed. When IF Flatness is ON, the Advisory Event “IF Flatness corrections OFF” will be cleared.

  • Page 355: Band Lock

    Service and Diagnostics Menus Service Key Descriptions Band Lock Provides the ability to tune the analyzer over as large a range as can be accommodated by the specified harmonic number and 1st LO frequency range. As a result, this feature can be used to check performance in the frequency band overlap regions.

  • Page 356: Lo Band Lock

    Service and Diagnostics Menus Service Key Descriptions LO Band Lock Provides the ability to tune the analyzer over as large a range as can be accommodated by the specified LO Band. As a result, this feature can be used to check performance in the LO band overlap regions. By definition, multi-band sweeps are not allowed.
