Characterizing a Filter

To use the relative marker

Continue from “To set up a frequency response measurement” or from “Using the absolute marker.”

1Move the marker to the largest part of the frequency response trace if it is not already there:

Press [Shift], [Marker].

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

Press [Marker], [zero offset]

or

Press [Shift], [Marker⇒ ]

3Move 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 frequency and amplitude reflect the value of the diamond-shaped marker relative to the offset (square) marker

The marker reflects the amplitude and frequency relative to the reference point
