MiniScan measurement mode views and analyzes the carrier levels of up to twelve channels and displays the results on a single screen. View the results in graph or table form:

Graph View

The user-configured channels are displayed in order of frequency, with start and stop channels indicated on the horizontal axis at the bottom of the graph. Use the right and left arrow keys to move the marker horizontally to the previous or to the next channel. Use the up and down arrow keys to adjust the reference level. Measurements are continually updated in this view.

Table View

Access the table view by pressing the VIEW softkey. Use the arrow keys to select Table and press ENTER. The MiniScan measurement table is comprised of data in the following categories for each tested channel: channel number, channel type, channel label, carrier frequency, signal level measurement and units, and (when enabled) limit-checking results. Measurements are not continually updated in this view.
