When displaying the saved image background color of the
screen changes to a light green color (Figure 28).
CONTEXT BUTTON FUNCTIONS ______________________________________________
- return to list.
- saves the signal under the marker (see section 3.5.2).
- transition to the current spectrogram with parameters corresponding to the stored image.
- pressing this button allows to subtract the saved spectrogram from the current.
___________________________________________________________________________________
Since with saving image not a static image is stored, but a dataset, when pressed
, the possibility
of cursor measurements is provided, both directly spectrogram and the transition to the
"OSCILLOSCOPE" sub-mode with measurements of signal timing parameters.
3.5.2 WORK WITH THE EXTRACTED SIGNAL.
When working with the spectrogram is possible quickly to
keep the information about the frequency and signal level for
subsequent analysis (manual creation of a list of frequencies).
Thus you can save the signal under the marker. Saving is provided
with a central frequency corresponding to the position of the
cursor and 10 MHz bandwidth.
To save signal press
. Check the appearance of
short inscription "Data is written! XXX. XXXX», wherein X - the
frequency value of the marker.
To view the list of saved signals, press
. This
displays a list of similar structure with lists created in the
"AUTOMATIC ANALYSIS" sub-mode (Figure 29).
3.5.3 WORK WITH THE SAVED RESULTS ANALYSIS
Access to stored results of the analysis performed by pressing
from the "AUTOMATIC
ANALYSIS" sub-mode. After that, there are 2 available shortcut keys:
- to store the result of a previous analysis. If there has not been analysis, the button will not
appear.
- to get a list of all previously saved analysis results for the current channel.
To get information about used memory, press
