Figure 4.38
The channel (video carrier level) diagram (figure 4.41) is located in the upper part of the
main window under the menu bar. The diagram represents the TV signals as vertical bars
measured by the Analyzer in accordance with the selected channel plan. The frequency
range of the diagram is the full operating frequency range of the IT-088. The diagram
panel has controls for selection of the area for viewing of the required spectrum region.
The signal spectrum panel (figure 4.42) represents amplitude versus frequency (signal
spectrum) response curve. The frequency resolution is 125 kHz. The viewing area of the
spectrum diagram in frequency and level are defined by the corresponding controls on the
channel diagram.
The marker panel (figure 4.39) represents the table of the active frequency markers.
The panel is located in the right part of the main window. It automatically appears when at
least one marker is active and shuts down when the last marker is deleted.

extension «*.it».
The program also allows exporting the data from the channel diagram, spectrum
diagram, of calibration characteristics, channel plans into files of standard formats, for
further calculations, pasting into the files of common formants, etc.
Export formats:
a) diagram image file *.bmp;
b) spectrum image file *.bmp;
c) text document *.txt;
d) MS Excel document *.csv.
