9.13 Power Tracker
Note: Power Capture can only be enabled on licensed M3i versions of Voyager.
The Power Tracker displays the power, voltage, and current at each time.
Select Report > Power Tracker, or click to display the Power Tracker.
If you select Power Tracker from the Report menu, you can select Hide, Full Screen,
Sync by Time, or Real Time Monitor (see “Power Tracker Toolbar” section below).
The left side shows power, voltage, and current levels. Right-clicking a column allows you
to select the vertical-scale origin. The origin is 0 or near the minimum measurement
value.
The horizontal axis shows time in milliseconds. You can navigate with the slider. The
slider sets the left vertical line. The distance to the right dashed vertical line represents
the sampling interval.
You can use time markers to measure times in this view. To delete markers, right-click the
marker and select Remove Marker(s).
You can show/hide minimum and maximum values for Power, Voltage, and Current by
right-clicking and choosing Show Min/Max Values from the popup menu.
You can go to the time at which Minimum or Maximum values of Power, Voltage, or
Current occur by right-clicking and choosing Go To from the popup menu.and then
choosing a submenu item.
The Power Tracker samples are acquired from the start of the recording to the finish.
Since packet traffic or other "Bus Condition" events can start long after the recording
starts or finish long before the recording ends, many power samples in these end ranges
can "map" to the first packet or last packet in a trace. For all events, when synchronizing
between the Power Tracker view and other views, the items associated in the other views
are the ones closest in time to the timestamp of the Power Tracker sample.
