CHAPTER 3
SIM 3 Configurations and Branches
3.1.9. Live Branch
The SIM 3 analyzer can only take measurements from one Branch at a time. This Branch
is known as the Live Branch. Data is being continually collected and displayed for the
measurement points defined in the Branch selected as the Live Branch.
NOTE: Make sure the check box to the right of the Live Branch field is
checked, and the Pause button has not been clicked in order for SIM 3 to take
measurements and display the information on the selected Branch.
Figure 3.14. Live Branch section of the Selector tab
Once the Live Branch has been selected, SIM 3 can display any of the measurements (Band
Spectrum, Line Spectrum, Delay Finder and Frequency Response) at the points defined on
the Branch. SIM 3 also allows you to view individual traces or multiple traces depending on
the View selected.
NOTE: If the check box on the Live Branch row is unchecked, the Live Traces
Hidden message appears in yellow in that row.
NOTE: If the Live trace area of the Names tab shows gray rather than the
standard blue color, it indicates that the system cannot find that switcher and
acquire data. Check the assignments in the Branch menu and the connections to and
addresses of the switchers.
