5 Key Reference

Delta

 

Activates a second marker at the position of the

 

first marker. (If no marker is present, two markers

 

appear at the center of the display). The amplitude

 

and frequency (or time) of the first marker is

 

fixed. The marker number is indicated above the

 

delta marker, and the same number is indicated

 

with an R (for example, 1R) above the reference

 

marker. Use the data controls to position the delta

 

marker. Annotation in the active function block

 

and in the upper- right corner of the display

 

indicates the frequency (or time) and amplitude

 

differences between the two markers. The markers

 

will be turned off if the scale type is changed

 

between log and linear.

 

Press Delta again moves the reference marker to the active

N O T E

marker position, so you are allowed to make delta

 

 

measurements from differing reference points without having

 

to turn off the makers and begin again.

 

 

 

The delta marker function permits signal-to-noise

N O T E

measurements provided the signal is a single spectral

 

 

component (sinusoid). Place a normal marker on the signal,

 

press Delta, place the delta marker in the noise, and activate

 

Marker Noise. The indicated amplitude indicates

 

signal-to-noise/Hz.
