Analysis and Processing of Result
Reading actual measurement points only/reading interpolated values
between measurement points
Reading actual measurement points only/reading
interpolated values between measurement points
The preset setting allows you to read, in addition to actual measurement points on the trace,
any point between measurement points by an interpolation calculation using the marker
(for example, you can directly enter the sweep parameter value of the desired destination
with the numeric keys to move the marker to that point). This can be done because the
marker interpolation mode is selected as the preset setting. Follow the steps below to set
one of two ways to read trace data using the marker: reading interpolated values between
measurement points (interpolation mode) or reading measurement points only
(non-interpolation mode).
Step 1. Activate the trace whose value you want to read (to which the setting is applied).
Step 2. Press the
[Marker]
key to display the Marker menu.
Step 3. Press the
MKR [ ]
key to select the marker interpolation mode or non-interpolation mode
(pressing the key toggles your selection).
NOTE In the marker non-interpolation mode, if you try to move the marker by entering a sweep
parameter value with the numeric keys and the entered value is not equal to the value of an
actual measurement point, the marker moves to the nearest measurement point having a
value larger than the entered value.
