Item Element Description
1
Analysis Time Control Click a button to select the value to be adjusted. In order, the buttons
represent Analysis Offset, Analysis Length, Spectrum Offset, and Spectrum
Length.
2 Position and Scale Adjusts the vertical scale and position.
3 Amplitude vs. Time graph The trace represents the entire acquisition record (at full horizontal scale).
The graph indicates the Analysis Length or Spectrum Length on the graph
with a darker background.
4 Autoscale button Resets the horizontal scale to display the entire acquisition record and the
vertical scale to show all trace points.
5 Horizontal Offset Adjusts the horizontal offset.
6 Results Timeline This fuchsia line indicates the portion of the record actually used for
calculating the selected result. For example: if a pulse measurement is
selected, it shows the period of the speci
fi c pulse. For a constellation display,
it shows the points included in the demodulation.
7 Horizontal Scale Adjusts the span of the graph. By decreasing the scale, the graph essentially
becomes a window that you can move over the acquisition record by adjusting
the offset.

Spectrum Length and Offset
Indicator This red line indicates the Spectrum Length and Offset. The longer the time,
the longer the bar. Adjusting the offset shifts the bar left or right.
9 Actual length display Displays the actual time for the selected value. If the user-adjusted length
extends past the end of the acquisition record, the realizable analysis length
is less than requested.
10 Analysis Length and Offset
Indicator This blue line indicates the Analysis Length and Offset. The longer the time,
the longer the bar. Adjusting the offset shifts the bar left or right.
11 Setting Adjustment box Click in this box to adjust the value selected by the Analysis Time Control
buttons.

NOTE.
The area with black background (not gray) in the Amplitude vs. Time Graph highlights the control
selected in the Analysis Time Control drop-down list.
