Homer Hot Measurement and Tuning System - S-TEAM Lab

Check/uncheck the Visible checkbox in order to show or hide a particular trace. Out of the three powers available
you may, for instance, wish to display only the incident power.
Line Panel
Check the Visible checkbox if you wish that the measured points be connected by a straight line. Select the color,
width (in pixels), and style of the line. Note that when the width is greater than one, only solid line will be drawn.
Markers Panel
The Markers panel defines whether and how the markers (dots) for each measurement point will be displayed during
the sweep and afterwards. It also depends on the Persist checkbox state (see below). Now suppose the Persist is
unchecked.
Visible
The Visible checkbox decides whether the markers will be drawn after completing the sweeping. For the behavior
while sweeping, see the description to Moving checkbox.
Moving
When the Moving checkbox is checked, a single point is shown on the trace running as the sweep progresses.
During sweeping, this happens regardless of the Visible checkbox state. After stopping measurement, the trace is
updated depending on the Visible status as follows:
If Visible is checked, the complete trace is shown, including all markers.
If Visible is unchecked, the markers are not displayed.
When the Moving checkbox is unchecked, the trace, both while sweeping and afterwards, is drawn with or without
all markers depending on the Visible state.
Pixels
When the Pixels checkbox is checked, a single dot (pixel) with the color equal to the Line color is left behind at each
measurement point in addition to anything else. You may wish to combine it with Moving Point in circular charts.
Marker Appearance
The marker appearance and size is defined by the rest of the controls in the Markers panel. Best try out and see. Line
Width affects only the thickness of the following three markers: + .
Other Controls
Persist
When the Persist checkbox is checked, the display acts as an oscilloscope with infinite persistence, not erasing
previous traces as the new trace is being drawn while sweeping. In this way glitches, e.g. temporary irregularities,
and measurement history can be captured.
Note, however, that this has only a volatile nature: resizing the display window clears all cumulated traces, leaving
only the final sweep.
The Persist function is also accessible from Trace|Persist menu item or the display window toolbar button .
If the Persist is ON the traces are displayed with or without markers depending on the Visible checkbox state.
Setting of Moving checkbox is irrelevant.
Clear and Go
When Clear and Go is checked, the display is cleared before start of each measurement. In this way, only one set of
traces at a time is displayed (like an oscilloscope). When the checkbox is unchecked, the contents of the display are
left unchanged and new traces are just added. In this way, more curves can be displayed simultaneously and visually
compared.
