For information on signature data, see Reviewing Data on page 161 .
For information on orbit data, see Review Orbit Data Screen on page 182 .
Review Orbit Data Screen
The Review Orbit Data screen lets you view the data in an orbit plot.
See Understanding an Orbit Plot on page 170 for more information about
orbit plots.
• To expand or compress the orbit, press the Up and Down arrows.
• To view the data in a time waveform, select Time X & Time Y from the
View menu.
• Use the Left and Right arrows to move the frequency cursor.
• Use the Up and Down arrows to move the amplitude cursor.
The cursor values appear above the signature data.
Cross Channel Phase
Measurements The Emonitor software and the Dynamix 2500 data collector support cross
channel phase measurement definitions. This topic lists the unique characteristics
of the Dynamix 2500 data collector that you may need to know when setting up
and collecting cross channel phase data:
• Set up a location in the Location pane for the two input channels.
• Set the Lo. Channel for the first location to 1.
• Set the Lo. Channel for the second location to 2.
IMPORTANT The Y-axis and X-axis are synchronized, which means the cursors are
in the same position on each trace in the Signature Data screen. The
X and Y axis will move together, and magnify as the display is
expanded.
