3.5.2 Operating Hints
The instrument is operated via the front panel keyboard. A thumbwheel switch on the rear panel
allows the user to select the TV system desired.
All pushbuttons under the PATTERN area of the front panel have LEDs to indicate the actual ON/OFF
state. The PURITY key has a step function; there are eight possible combinations, which are indicated
by three LEDs R-G-B.
After POWER ON and performance of the self-test routine, the instrument automatically switches over
to the operating mode to which it was set before POWER OFF. The instrument is mostly insensitive
to keyboard operation errors, which cannot cause any damage.
3.5.3 Test Pattern Selection
The user can select 18 basic and 3 special test patterns via the 12 PATTERN pushbutton. In addition
many of the test patterns can be combined, so that more than 70 different test patterns are available.
Refer to the following table.
By pushing a respective PATTERN key the required test pattern is switched on and off the assigned
LED is lighting. Each test pattern can be combined with the ‘circle’ pattern. If an additional test pattern
is selected to which the pattern already chosen cannot be combined the surplus patterns are
switched off.
The PURITY key has a step function; repeated pressing effects subsequent selection of ail colors of
the color bar signal in the following sequence: red, green, blue, magenta, yellow, cyan, white, black.
The chrominance signal in every pattern (including burst) is fixed to 100 % and can be turned off by
pressing the CHROMA OFF pushbutton.
