Presetting the Spectrum Analyzer

Preset provides a known instrument status for making 
measurements. There are two types of preset:

Factory Preset

Restores the analyzer to its factory- defined state. Please 
refer to 

“Factory Preset State”

on page 92 for details.

User Preset

Restores the analyzer to a user- defined state.

Press 

 > Pwr on/Preset > Preset Type

 to select the preset 

type.

When 

Preset Type

 sets to 

Factory

, pressing 

 > Preset

 

triggers a factory preset. 

When 

Preset Type

 sets to 

User

, pressing 

 > Preset

 displays 

both 

User Preset

 and 

Factory Preset 

softkeys, then select the 

preset you need.

Setting up a User Preset

If you constantly use settings that are not the factory 
defaults, use the following steps to set up a user- defined 
preset:

1

Set customized parameters as required.

2

Press

 

 > Pwr on/Preset

 

> Save User Preset

, to save current 

instrument settings as the ‘user preset’ state. the user preset 
do not affect the default factory preset settings.

Viewing a Signal

Refer to the procedures below to view a simple signal.

1

Press 

 >

 

Pow on/Preset > Preset Type > Factory 

to enable 

the factory- defined preset state. 

2

Press 

 > Preset

 to restore the analyzer to its 

factory- defined state.
