The R&S ZVH starts the spectrogram measurement. The data is written directly to the
connected storage device in one or more files, depending on the overall length of the
spectrogram . the longer the recording last, the more files are created.
When you stop the recording, the
R&S ZVH shows a message
containing the directory where the
measurement data has been saved.
When you playback the spectrogram,
the currently used file is indicated in
the display.
Note that it might take a little while to access a new file during spectrogram playback (a
corresponding message is shown).
Configuring Long Time Spectrograms
You can define several characteristics of the long time spectrogram in the “Measure
Setup” menu:
● Recording Mode: Selects the way the spectrogram is controlled.
-
“Timer”: Recording starts and stops on a certain date and time. You can define
the date via
the “Start / Stop Date” and “Start / Stop Time” menu items (for
example from 6:00 am to 6:00 pm on January 1st in the year 3000. You can
also define a “Duration” instead of specifying a stop time.
-
“Immediately”: Recording begins immediately, and you can define a “Duration”
(for example 6 hours). Otherwise the recording stops when you deliberately so.
-
“Limits Failure”: Recording starts or stops when a limit has been violated.
Select the details with the “Limits Save Mode” menu item.
In any case, you can stop the recording deliberately any time by turning the
long time spectrogram off.
-
“Stop Recording If Battery Low”: Recording stops when the battery level runs
low.
● Recording Speed: Selects if the spectrogram measurement time is defined
automatically by the R&S ZVH or manually. In the latter case, define the
measurement time with the “Manual Recording Interval” menu item (Example: a
spectrogram line is added every 100 ms).
