2.13.7 Record Time Plot
The RECORD TIME PLOT menu allows visualizing the detected power values over time during a record. The vertical
axis is transformed into a time axis – the bottommost row of a time plot corresponds to the newest sweep and the uppermost
row corresponds to the first recorded sweep. Input power levels are indicated with different colors. The color legend is dis
-
played above the graph.
The color legend is generated based on the currently selected MAX (highest limit of the vertical
axis) and MIN (lowest limit of the vertical axis) values of the displayed input power range.
Adjust them at the SCALE menu before starting a new record.
TIME PLOT is not applicable for MAXHOLD, MIN/MAXHOLD and CUMULATIVE trace modes,
thus NEW RECORD button is not available when these trace modes are selected.
To start a new record with the currently selected sweep settings, tap NEW RECORD (NEW RECORD button turns on
continuous sweep). The filename is assigned automatically, but it can be changed afterwards when the file is open with the
button RENAME RECORD. The maximum length of a record is 30 minutes. If the recording is not manually stopped earlier either
by tapping the NEW RECORD button again (thus disabling it) or by tapping the OPEN TIME PLOT or BACK buttons, a new conse-
quent record will be started automatically.
Airscout Spectrum can be left at a site with NEW RECORD button active and the created records
can be examined later. While charging with the supplied power source, Airscout Spectrum can
record files continuously.
Records are sorted by the time they were created and the latest record is on top of the list. The start time of the re-
cord and the number of frames (sweeps) recorded is given under the filename. Navigate the records list by using the slider and
the arrows. To view a record using the time plot visualization, tap on it to select it, then tap OPEN TIME PLOT. Tap on the upper
part of the graph to view older sweeps that go beyond the currently displayed plot. Tap on the bottom part of the graph to get
back to newer sweeps.
Tapping the RECORD OPTIONS button opens the record with the regular visualization, see
RECORD
. To then return to
the time plot visualization, tap the button OPEN TIME PLOT.
A record can be deleted with DELETE RECORD or from the folder “RECORDS“, when Airscout Spectrum is connected to
a computer.
If deleting a record manually from the “RECORDS” folder (when Airscout Spectrum is connected to
a computer), delete also the time plot file – it has the same filename as the record file that has the
extension
“.RSC”.
