This area consists of the start and stop frequency (as provided by the
sweep plan transmitted from the headend transceiver) and the forward sweep
telemetry level. The forward sweep telemetry level can be converted to
dBmV, dBm etc from the configuration settings of the DSAM. If zoom is
active, a zoom icon is also displayed.
MARKER STATUS AREA
The Reverse Alignment measurement mode also contains an area referred to
as the Marker Status area (below lower subtitle bar). This area consists
of the marker name (A or B), marker frequency (in MHz), and measured signal
level for the frequencies which the markers are on. The black square around
the letter A or B below the trace graph shows the active marker. The delta
value (in dB) between the markers is also displayed.
