Scan

The XR-3 Signal Level Meter includes a Limit Scan feature that performs a quick scan of up to 5
transponders on a satellite, checks the values against pre-determined limits, and provides a
pass/fail indication. Use this test to quickly verify your installation against recommended level
and quality values.

Specifications

1)  Up to 5 transponders per satellite may be tested
2)  Up to 10 total satellites may be stored
3)  Signal quality test (IRD signal quality number – i.e. 0 to 100 signal quality scale)
4)  Signal level test
5)  Signal quality limits defined for individual transponders
6)  Signal level limit defined overall
7)  Limits are changeable and are stored in the instrument

Setup

Use the normal meter setup for whatever type of system you are installing. When the installation
is complete, select “Limit Scan” from the main menu:
