You will observe on the function keys on

the right of the screen.

These are referred to as soft keys as their

function changes depending on the

nature of the current display – the

functions are shown on the right of the

display as you will see in the following

images taken from the instrument’s

display.

Averaging

Various averaging modes let you further refine spectrum

analysis measurements.

Time averaging extracts repetitive signals out of the noise

while rms averaging reduces the noise to its mean value.

Exponential averaging, available for both time and rms

averaging, is useful for reducing the noise while following

changing signals—tracking the resonance shifts in a

fatiguing structure for example.
