theabsolutemarker.”
1 Move the marker to the largest part of the frequency response trace if it is not
already there:
Press [

2 Establish the reference point for the relative (offset) marker:

3 Move the marker with the knob to view the relative gain/loss of this particular
filter at different frequencies.
The offset marker allows you to establish a reference point with the
square-shaped marker. As you move diamond-shaped marker, the value
displayed by the marker readout reflects the difference between the reference
point and the marker.
The marker reflects the amplitude and frequency relative to the reference point
The marker frequency and amplitude
reflect the value of the diamond-shaped
marker relative to the offset (square)
