Do like this:
* Tune in any TV-channel on TVLOOK and chose ITS-mode (button nr 2 in the TV-menu).
TVLOOK shows an ITS-line (default setup is line 19 but a TV-channel shows the ITS-
information normally on a couple of the lines between 15 and 25, alt. 325 and 335).
The picture below shows how an ideal ITS-signal should look like (correct level of the videosignal).
* Find an ITS-line by pushing the control-button one time (
V-line
”Videoline” lit on top of the LCD-
display).
* Turn the knob until a valid ITS-line been found (ex. it may be line 19 for the video-signal level and line
20 for the presentation of the frequency response).
- A video-signal shall be 1 Volt ”peak to peak” i.e. from the synclevel floor to top.
- The sync-pulse (above the burst – linesync) shall be 0.3 Volt from the synclevel floor which means that
it is 0.7 Volt from black to white.
* The TVLOOKcan present the ITS-line in two ways; plotted or drawn. The drawn line looks “better”
and is more complete than the plotted one.
At the other hand, the plotted one is better when the line is being continuos scanned (when, for
example, adjusting modulator video-levels etc.).
Chose between drawn or plotted with button nr 3.
Chose continuos scanning with the auto-button (nr 2) or ”write one time” with the “trigg”-button (nr 1).
* It is easy to memorize an ITS-line by simply pushing the ”Memory”-button and, thereafter, chosing a
free memory position (with the knob).
The memory positions (pos 00-99) is shown in the bottom of the LCD-display.
After selecting a free position, push the “save” button (button nr 1).
* Retrieve a saved ITS-line by chosing ”Memory” (button nr 4) in the ITS-menu.
Select, with the knob, the memory-position to load. Push the ”Load”-button (nr 2) and the ITS-line is
retrieved to the picture-screen.
