Level measurement mode views and analyzes the signal level of each carrier within a channel (as defined by the active channel plan). In Channel Tuning mode, carrier levels can be checked in relation to user-configured limit sets. In Frequency Tuning mode, signal levels can be measured at any discrete frequency within the tuning range. Digital performance measurements are conducted on digitally modulated channels in the selected plan.

When necessary, the user can troubleshoot an installation by performing this test at various locations to determine which components require repair or replacement. Test results can be stored for later reference.
