Understanding
Sweepless Sweep
Results
The Sweepless Sweep measurement mode provides signal levels of
all frequency points which are then displayed on a graph.
Measurement
Information Area
The reference filename, test point compensation icon/value, and the
tilt compensation value appear in this area above the graph.
When a sweep limit value is entered, a pass/fail indicator also is
displayed on the far left side of the subtile bar above the graph.
Graph
The graph updates with each new set of sweep data received by the
meter. If Sweep Limit is turned ON, a pair of horizontal markers appear
on the screen to indicate the limit boundaries based on the limit value
entered. These appear only when sweep limit value is ON within
Sweep Settings. An error message automatically is displayed if the
sweep telemetry level is too low.
Graph Information
Bar
This area consists of the start and stop frequencies (as provided by the
sweep plan transmitted from the headend transceiver and telemetry
level). If zoom is active, a zoom icon also is displayed and the start and
stop frequencies are updated to match the zoom view.

NOTE
The sweep attempts to use the last used reference file. If the last
reference file is incompatible with the current sweep plan, or if there
is no reference file, the entry REF field displays “NONE.”
