Click Vertical or Horizontal in the math dialog box to

recall the FFT vertical or horizontal settings dialog box:

A. Set the vertical scale and reference level

B. Set the unit (dBVrms, Vrms, and dBm). When the unit

is dBm, the oscilloscope will automatically calculate the

dBm value based on the Ext Load value set in

area

C. Set the external load, which is used to calculate the

correct dBm result

D. Return to the previous menu

E. Set the center-span frequencies

F. Set the start-end frequencies

Unit

The unit of the vertical axis can be set to dBm, dBVrms, or Vrms. dBVrms and Vrms respectively using

either logarithmic or linear scaling. dBVrms is recommended to show larger dynamic ranges. dBm is a

power unit, the correct result can be obtained only if the value of Ext Load is set to be consistent

with the load impedance of the actual measured signal.

Vertical Control

 Click Ref Level to set the reference level of the FFT waveform by the mouse wheel or the virtual

keypad.

 Click Scale to set the vertical scale of the FFT waveform by the mouse wheel or the virtual

keypad. The reference point for vertical scale scaling is the reference level.

Horizontal Control

 Click Center to set the center frequency by the mouse wheel or the virtual keypad.
