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
channel, 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 (fig-
ure 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 particu-
lar channel for the duration of the Continuous Scan (figure 13k).
Channels with very low RF signals (below -70 dBm) should be consid-
ered 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
