Analyzing Data

Retrieving Measurement Results at Specified Points

Markers allow you to retrieve measurement results at your specified points. You can use up

to eight markers for each trace, and you can move them to any point on the trace. In

addition to the regular markers, you can use a reference marker.

Showing/Hiding Markers

To show or hide markers including the reference marker, use the following command:

• :CALC{1-4}:MARK{1-10} on page 263

NOTE You can move markers or retrieve the data at a marker even when the markers are hidden.

NOTE The display of the reference marker is turned on or off when you turn on or off Reference

Marker mode.

Turning On or Off Reference Marker Mode

Turning on Reference Marker mode provides relative marker values with respect to the

reference marker (by deducting the value at the reference marker from the value at a

particular marker).

To turn on or off Reference Marker mode, use the following command:

• :CALC{1-4}:MARK:REF on page 262

Setting (Changing) and Retrieving Stimulus Value at Marker Positions

To set (or change along the frequency axis) the stimulus value at a particular marker or the

reference maker or retrieve the current stimulus value, use the following command:

• :CALC{1-4}:MARK{1-10}:X on page 279

When Reference Marker mode is on, the stimulus value at a regular marker is a relative

stimulus value obtained by deducting the stimulus value at the reference marker from the

actual stimulus value at that particular marker.

Retrieving Measurement Results at Marker Positions

To retrieve the measurement results (response values) at a particular marker or the

reference marker, use the following command:

• :CALC{1-4}:MARK{1-10}:Y? on page 280

When Reference Marker mode is on, the response value at a regular marker is a relative

value obtained by deducting the response value at the reference marker from the actual

response value at that particular marker.
