key.

Initial Settings

If you have already been into Modulation Analysis mode since the instrument was
powered up, then the screen displayed and the settings in force will be exactly as
they were when you last switched out of Modulation Analysis mode.
When you put the instrument into Modulation Analysis mode for the first time
after a power up, the Monitor Spectrum screen will be displayed with a center
frequency setting of 1.0 GHz and a span of 3 MHz. This Monitor Spectrum
function allows you to check that there is a signal to be measured.
The center frequency can be changed by pressing
required frequency using the numeric keys. The span can be altered by pressing
Span and entering the required span using the numeric keys.
Before making a measurement, make sure the mode setup and radio standard
parameters are set to the desired settings. Refer to
Chapter 6 , "Front-Panel Key Reference,"
in changing parameter settings.
If you want to set the instrument (including the Error Vector Magnitude (EVM)
mode settings) to a known, factory default state, press
mode setup and all of the measurement setup parameters to the factory default
parameters. Note that

mode. You must re-access the EVM mode after the preset operation is completed.
You can set the instrument to use User preset or Factory preset under the
front panel key. If you set the preset to User, the instrument displays a Preset
menu when you press Preset
defaults or the
Factory
using user defaults, refer to the ESA Spectrum Analyzers User's Guide.
If you want to set only the EVM mode to a known, factory default state, press
