The PM 5415 and PM 5418 multi-system color TV pattern
generators are used for test and measurements, and
maintenance and repair of video equipment, such as color TV,
black and white TV, videocassette recorders,
teletext/Antiope receivers, video monitors, and cable TV
Applications for pattern generators are found in
development, production, quality control, and educational
areas and in TV studios and service workshops.
The instruments cover the complete RF frequency range from
32 MHz to 900 MHz. They operate according to the CCIR or
RTMA TV systems for either PAL or NTSC respectively. PM 5418
also offers SECAM.
The 18 basic test patterns and over 100 different test
pattern combinations are selected via the PATTERN keypad.
The patterns cover current and future purposes. Every test
pattern is available in 16:9 and 4:3 Aspect Ratio format.
The microprocessor control enables simple and rapid
operation; it also allows a program sequence to be stored
and recalled. Up to 10 instrument setups may be stored in
nonvolatile registers; they can be recalled in any order.
Each program may contain RF vision frequency, test pattern,
or a combination of patterns, as well as any of the sound
On PM 5418, the TV system is selected via the PAL/NTSC/SECAM
key and two thumbwheel switches on the rear panel of the
instrument. On PM 5415 the TV system is selected by the PAL/
NTSC thumbwheel switch. The line frequency is automatically
selected, either 15625 Hz for CCIR or 15734 Hz for RTMA.
Line and field synchronization are determined according to
the appropriate TV standard and are available as line and
field frequency for external applications at the BNC
connector at the front panel.
A part of the vision carrier section consists of a 4-digit
LED display. The first digit indicates which of the
selectable memory registers are in operation. The second,
third, and fourth digits indicate the vision carrier
frequency in MHz.
Fine adjustment of the frequency setting in increments of
0.25 MHz, 100 kHz steps in the lower frequency ranges, is
done by pressing the up and down steps keys near the
display. LEDs indicate the selected value. Frequency tuning
through the RF range is done by holding one of the step keys.
Keys for STORE and RECALL allow operation of the memory. The
RECALL facility can also be used in combination with the
step function to move swiftly through the sequence of stored
The VIDEO OUTPUT is 1 V standard in stop position; it can be
set from 0 to 1.5 V. The CHROMA amplitude is fixed to 100 %
in stop position; it can be set from 0 to 150 %.
