 If you activate the Noise Mkr function under the Marker Fctn key, the result of
the noise measurement will be corrected automatically and normalized to 1 Hz.
The application of Delta marker
Measuring the signal-noise ratio of single spectrum signal, for example, separately
place the Reference and Delta Markers onto the signal and noise, the amplitude
shown in the measurement result is the signal-noise ratio.
2.5.1.4 Delta Pair
One of the marker types. When selected, a pair of markers will appear on the trace,
which are the Reference Marker (marked as a combination of the marker number and
letter “R”, such as “1R”) and the Delta Marker (marked as the marker number, such as
“1”).
Key Points:
 You can use the knob, direction keys or numeric keys to set the location of the
Reference Marker (selecting Ref) and the Delta Marker (selecting Delta).
 This is different from the Delta type marker in that you can modify both the
Reference and Delta Marker. Additionally, both the X and Y values of the
Reference Marker are stable in “Delta” type during the sweep, but the Y value of
the Reference Marker is updating along with the sweep in “Delta Pair” type.
2.5.1.5 Span Pair
One of the marker types. When selected, a pair of markers will appear on the trace,
which are the Reference Marker (marked as a combination of the marker number and
letter “R”, such as “1R”) and the Delta Marker (marked as the marker number, such as
“1”).
Key Points:
 You can use the knob, direction keys or numeric keys to set the location of both
the Reference Marker and Delta Marker at the same time.
