[I] Test Video
Test Video is used to check whether the video signals under target acquisition and tracking are inputted to and
processed in the target processing circuit normally.
However, it is sufficient to check that VDH in TEST VIDEO is displayed.
The start of the Test Video mode is available only in the Standby mode.
Procedure 1 Press [STBY] key.
The equipment will enter the standby state.
2 Press [TT MENU] key.
Press [6] key.
The TT Test Menu will appear.
3 Press [1] key.
The Test Video setting screen will appear.
4 Press a numeric key to select a video
signal you want to set.
The selected test video will be set.
The test video is displayed in the background of
the radar display.
In general, VDH is sufficient for target display checks in test video mode.
If any target displayed clearly in the radar display is not displayed in the Test Video mode, the target detection
circuit of the TT system may have a trouble.
z TEST VIDEO may not appear for targets that are not
acquired nor tracked, or if the [GAIN] and [SEA]
controls are adjusted properly
