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 displayed 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 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 consequent
record will be started automatically.
Spectrum Compact 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, Spectrum Compact 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 record 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 back 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
Spectrum Compact is connected to a computer.
If deleting a record manually from the "RECORDS" folder (when Spectrum
Compact is connected to a computer), delete also the time plot file – it has the
same filename as the record file that has extension ".RSC".
To exit the OPEN TIME PLOT submenu, tap BACK. To exit the RECORD TIME PLOT
menu and return to the TOOLS menu, tap BACK.
