5 Test conditions
5.1 General
The test requirements are designed to determine the performance level of black and white
CCTV monitors. The main operating parameters are described.
Monitors shall also conform to the current safety standards for electronic devices.
If a method of measurement and a standard exists for a given parameter, this has been
used in the following tests.
If a method of measurement and standard does not exist for a given parameter, the method
and standard indicated in this standard takes into account the objectivity, repeatability, and
complexity of the tests.
5.2 Test equipment
Test equipment shall be calibrated to tolerances in relation to the required accuracy of the
respective measurements.
The test equipment normally required is:
a) Video wave form monitor or oscilloscope, preferably with facilities for triggering of
the sweep from the field or line pulses of the video signal. Its input impedance
shall be at least 1 MΩ. For some measurements it is essential that the oscilloscope
has an adjustable delay relative to the field synchronization for the selection of
individual TV lines. A marker pulse output indicating the selected line on a monitor
is useful for measurements on individual TV lines.
b) Luminance meter, indicating cd/m².
c) Test signal generator capable of generating the test signals specified in 5.3.1.

This signal may be a white window or grey scale with white reference.
The APL of the signal shall be 60 % or less and the composite video signal shall have the
standard level as specified in 5.3.1.
The test signals used in this standard are:
a) Window signal: The window signal to be used in specific tests within this standard
shall generate a displayed rectangle having a 4/3 aspect ratio and an area equal
to nominally 20 % of the normal active raster area (see Figure A.1). This signal
may be generated electronically or by a TV-camera.

c) Linearity test pattern, see Figure A.3.
d) Grey scale signal, see Figure A.4.
e) Frequency burst signal, see Figure A.5.
f) Checker board signal, see Figure A.6.
5.3.3 Test preparations
If provisions are available to switch the monitor for NORMAL SCAN/UNDERSCAN
operation, the monitor shall be operated in the NORMAL SCAN mode.
If the monitor includes a switch for DC restoration ON/OFF, it shall be operated in the ON
mode.
The aspect ratio of the displayed area shall be 4/3.
By means of the brightness and contrast controls, the black reference in the video signal
shall be set to subjective black, and the white reference in the video signal set to the
manufacturer’s rated maximum luminance.
To allow for variations in black level, subjective black may be re-established by adjusting
the brightness control only when switching to test signals of different APLs, unless specified
otherwise.

meter or a TV camera focused on the monitor face plate. For these tests the ambient light
falling on the display shall be ≤ 3 lux.
