Using Markers
To Use Delta (
∆
) Marker Mode
In delta marker mode, a reference marker is placed at the active marker
position. All marker values are then displayed in reference to this delta
marker. When the amplitude of the measurement trace changes, the
reference marker value also changes. The delta marker is represented by
a triangle pointing up (
∆
) with a delta symbol (
∆
) below it rather than a
number.
Limit testing can be performed on delta amplitude and delta frequency
using specific markers. See
“To Use Marker Limit Functions” on
chapter.
To follow along with this example, set up the instrument for an S
21
forward transmission measurement of the bandpass filter that was
shipped with your instrument.
1. Press
to move marker 1 (the active marker) to the maximum
value on the trace.
2. Press
to place a reference marker at the active marker
position.
3. Press
to place marker 1 to the minimum point on the trace.
4. The difference between the markers' frequency and amplitude value
is shown in the upper-right corner of the analyzer screen.
5. Press
. Use the front panel knob to
move marker 2 towards the right-hand side of the display screen.
Note that the marker 2 values are also in reference to the delta
marker.
