Application
The new digital studios need cost effective
and reliable synchronization for the
main equipment to work reliably. For this
purpose PTV offers a fully integrated
solution eliminating any costs associated
with modular structures, support of
many different signal types and fancy
operating features.
All solutions have been carefully designed
to meet all requirements for the
modern studio and editing.
PTV/DK-Technologies introduces the next
generation of the Compact Varitime
TM
Sync Generator.
The PT 5202 includes all basic features
for professional sync, timing and test
signals in one half-sized box.
New is a user friendly front plate control
and moving text on the color bar pattern.
Ease of Operation
A clearly labeled front plate with separate
pushbutton for quick access to
main functions, allows intuitive selection
of main functions.
When a main function is selected, the
detailed menu structure is opened on
the LCD screen. In the menus all programmable
parameters can be
managed, e.g. timing, test signals and
audio parameters.
Also the front plate gives instant access
to 4 presets.
In addition to the front plate control, all
configurations can be set via an RS232
interface.
To facilitate the remote control without
having to make a software code, a Windows
application program is included
with the instrument.
The Windows interface makes it easy to
manage all timing, test signals and
audio features in one screen. Modification
from factory preset can be saved as
a file on the PC or uploaded to the
PT 5202 as a setup. The setup is uploaded
to PT 5202 in an instant mode or
stored as a preset in the instrument.
Communication between PT 5202 and
PC via standard RS-232 protocol, makes
it possible to use any kind of PC.
Master/Genlock Applications
The PT 5202 is designed to manage slave as well as master operations, as a stand
alone unit. In systems where PT 5202 operates as a master unit it is controlled
by an internal TCXO reference oscillator. For use in applications where the PT
5202 operates as a slave the gen-lock function is used. The gen-lock function
features gen-lock to NTSC and PAL video signals, Black Burst, composite or a 10
MHz reference clock,
e.g. from a GPS receiver. Further more the gen-lock function features timing and
active loop-through of the gen-lock signal.
Analog Black Burst Outputs
The sync generator is equipped with three VariTimeTM analog Black Burst
outputs. Each of these Black Burst outputs is individually fully timeable (±4
fields in PAL, ±2 fields in NTSC) and can be configured as NTSC or
PAL-generator, in any combination. NTSC signal configurable with or without
set-up.
SDI Output
A SDI Test Signal generator, fully configurable in system and timing, is
also included. This Test Signal Generator provides standard color bars and
test-patterns, according to SMPTE and EBU. For diagnostics in studio setups a
list of test signals is available. The SDI output includes codes for embedded
audio, featuring data for 1kHz Stereo and silence The SDI signals are in general
generated as 10 bit signals, except one of the EBU 75% Color bar signals which
is generated with 8 bit according to ITU 801
Analog Video Outputt
The analog video generator is based on the same digitally signal definitions as
the SDI Test Signal Generator. It outputs the same test pattern in the same
system and with the same sync timing. The output is configurable with or without
set-up-
This output is primarily for testing purposes and is not usable as a timing
reference as the output is not consistently locked to the BB's. The colour-frame
(ScH phasing) of this output may randomly be one of four at power-up.
Source Identification
One line of 16 characters can be programd into the EBU Color bar and the SMPTE
bar. The text is fixed positioned or or can be made scrolling up/down to reveal
if a digital transmission link is a freeze condition.
Audio Generators
PT 5202 contains an Analog Audio Generator or an AES/EBU Serial Digital
generator. One format at the time as
both signals are available on the same
XLR connectors.
Analog Audio Outputs
The Analog Audio generator provides three different test tones in a number of
levels. The output is available in stereo, mono and includes click markers for
identification of left channel. The click interval is selectable.
AES/EBU Serial Digital Audio Outputs
The Serial Digital Audio generator provides three different test tones in a
number of levels. The output is available in stereo, mono and includes click
markers for identification of left channel. The click interval and samplings
frequency for the AES/EBU output is selectable. The generator also features
system lock and timing facilities for elimination of Lip Sync problems.
WordClock Output
The WordClock signal is a continuous reference clock operating at HC-MOS
level, used for synchronizing audio equipment. The sampling frequency of
44.1 or 48 kHz is selectable .The 48kHz is phase locked to video, while the
44.1kHz is frequency locked only.
Presetss
Four complete presets are included to make it easy to change the
configuration for different setups. Switching between the presets is possible
from the front panel. The number of presets stored in the configuration PC is
unlimited.
