13.4.2.5. RF Scan (F6)
Use the RF scan to get a "picture" of the potential RF interference in your
location. You should perform a scan before every program so you can
Scan results are shown in several ways. A double green line indicates a
Sabine transmitter is active on the associated channel. Each green line
shows RF signal levels for left and right antennas respectively. This RF
Diversity function is especially useful for antenna positioning when using
distribution amp. A red line indicates ambient RF is present on the chan-
nel, at a level indicated by the scale on the left side of the chart. A dotted
red line indicates a previous RF level from an earlier scan, and a small
yellow "T" indicates the peak RF level observed over the entire time. Left
click on any line or channel number brings up the "RF Scan data history"
window, allowing you to disable the specific channel (figure 13J). If you
chose Continuous Scan you can also choose to see the Channel Details
(figure 13k) and a history of all RF activity on a particular channel for the
duration of the Continuous Scan (figure 13k).
Channels with very low RF signals (below -70 dBm) should be considered
open channels. We include this low level measurement so you can see
the activity in your location, but the Sabine transmitters will overpower
and ignore those very low signals.
You can choose to disable all channels with ambient RF levels above a
