5 Key Reference

Amplitude

Activates the reference level function and access the associated softkeys to set functions that affect the way data on the vertical axis is displayed or corrected.

Ref level

Activates the reference level function.

The reference level is the amplitude power or voltage represented by the top graticule on the display. Changing the value of the reference level changes the absolute amplitude level (in the selected amplitude units) of the top graticule line. To change the reference level, use the arrow keys, the knob, or the numeric keypad. Pressing any digit (0 through 9) on the numeric keypad brings up the terminator menu.

Attenuation

 

Toggles the input attenuation between Auto or Man.

 

The input attenuation ranges from 1dB to 51 dB

 

and allows you to set the attenuation level in 1 dB

 

increments when Attenuation is set to Man.

 

The input attenuator, normally coupled to the

 

reference level control, reduces the power level of

 

the analyzer input signal at the input mixer. The

 

attenuator is recoupled when Attenuation is set to

 

Auto.

 

To prevent damage to the input mixer, do not exceed a

C ACUATUI O- N

 

power level of +33 dBm at the input. A granted power

 

level for stable sensitive measurement is less than 20

 

dBm.
