2Safety
Read this chapter carefully before installation and use of the instrument.
2.1 Introduction
The instrument described in this manual is designed to be used by properly trained personal
only.
Only qualified personnel who are aware of hazards involved shall carry out adjustment,
maintenance and repair of the exposed equipment.
2.2 Safety Precautions
For the correct and safe use of the instrument, it is essential that both operating and servicing
personnel follow generally accepted safety procedures in addition to the safety precautions
specified in this manual. Specific warning and caution statements, where applicable, are found
throughout this manual.
Warning and caution statements and/or symbols are marked on the instrument as well.
Special attention must be paid to the following issues:
♦Protective grounding of the instrument is required for the accessible terminals to be safe.
(IEC 1010-1 Safety class I instrument)
♦The actual environmental conditions must be checked against the specification.
♦Mains voltage must be inside the specified range.
The opening of covers or removal of parts, except those to which access can be gained by
hand, is liable to expose live parts and terminals.
If adjustment, maintenance, or repair of the opened instrument is unavoidable, only a skilled
person who is aware of the hazards involved must carry it out.
2.3 Use of Caution and Warning Statements
Caution
Used to indicate correct operation or maintenance in order to prevent damage to, or destruction
of equipment or other property.
Warning
Used to indicate a potential hazard that requires correct procedures or practices in order to
prevent personal injury.

2.4 Impaired Safety Protection
Whenever it is likely that safe operation is impaired, the instrument must be made inoperative
and secured against unintended operation. The appropriate servicing authority must be
informed.
For example, safety is likely to be impaired if the instrument fails to perform the intended
functions or shows visible damage.
The instrument is NOT equipped with a mains interruption switch, and thus to be made
inoperative by unplugging its mains connection lead, or by other means prior of the instrument
WARNING: Protection provided by the equipment may be impaired if the equipment is used in a
manner not specified by this manual.
2.5 Technical Specification
This manual provides technical information important for safe operation of the equipment.
Please refer to chapter 4Product Data for information regarding technical specifications and to
chapter 5Installation and chapter 6Operating Instructions regarding instructions for use.

Altitudes up to 2000m
Temperatures between 5°C and 45°C
Maximum relative humidity of 80% for temperatures up to 31°C decreasing linearly to 50%
relative humidity at 40°C.
The instrument is equipped with a number of input and output terminals as described in chapter
4Product Data.
The terminals are protected from becoming live by means of basic insulation and protective
screening.
Whenever it is likely that safe operation is impaired, the instrument must be made inoperative
and secured against unintended operation. The appropriate servicing authority must be
informed.
For example, safety is likely to be impaired if the instrument fails to perform the intended
operations or shows visible damages.
2.6 Electrostatic Sensitive Devices
All IC and many other semi-conductors are susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce lifetime drastically.
When repairing, make sure that you are connected to the same potential as the mass of the set
via a wrist wrap with resistance. Keep component and tools at this potential.

3Introduction and Applications
3.1 Introduction
The PT 5201 Compact VariTimeTM Sync Generator includes all basic features for professional
sync, timing and test signals in one half-sized box.
The new digital studios need cost efficient and reliable synchronization for the main equipment
to work reliably. For this purpose PTV offers the PT 5201 as the fully integrated solution
eliminating any costs associated with modular structures, support of many different signal types
and extensive operating facilities.
Analog Black Burst is still routinely used for timing purposes, also in digital installations, where
processing delays are often on the order of several fields.
The PT 5201 Compact VariTimeTM Sync Generator is designed with the multiple delays of digital
television installations in mind, but also fulfils all synchronization requirements when used with a
combination of digital and traditional analog video systems.
The PT 5201 Compact VariTimeTM Sync Generator is a multi-standard sync generator and
provides sync and test signals for both NTSC, PAL and for SDI outputs of 525/59.94 and 625/50
systems.
Each of the reference Black Burst outputs and the Test Signal Generator output can be
individually selected in system (NTSC/PAL) and timed in fine steps over the complete
sequence.
The serial digital black and test signals can be timed with a resolution of 37 ns over a ±1 field
range.
The analog black bursts are timeable in sub-nanosecond resolution over a ±4 fields sequence
for PAL and ±2 fields sequence for NTSC.
The timing of analog Test Signal Generator follows the timing of the SDI generator, i.e. with a
37ns resolution but over a ±4 fields sequence for PAL and ±2 fields sequence for NTSC.
3.2 Configuration
The operation of PT 5201 Compact VariTimeTM Sync Generator is based on a PC Remote
Control. The PC Remote Control program makes it easy to manage all timing, patterns and
audio features in one screen.
The settings for the PC Remote Control are either loaded from the PC or downloaded from the
generator. When the settings are loaded from the PC the data is transferred immediately to the
generator, overwriting the actual state.
At exit from the panel, data is stored in a file on the PC for later use.
Four presets can be stored in the instrument and also in 4 separate files on the PC. Any preset
can then be recalled either from the PC or from the generators internal memory.
The hidden button on the front plate can select the stored presets in the generator.
Communication between PT 5201 and PC via standard RS-232 protocol makes it possible to
use any kind of PC.
Status of current functions and systems will be displayed at any time corresponding to the
LED’s on the PT 5201 front panel.

Introduction and Applications PTV PT 5201
Revision 2 Operating Manual

3.3 Applications
The PT 5201 is designed to manage slave as well as master operations as a stand-alone unit.
In systems where PT 5201 operates as a master the reference is locked to an internal, high
stability TCXO oscillator (Temperature Compensated Xtal Oscillator)
For use in slave applications the genlock function is used.
The genlock function features genlock to NTSC and PAL video signals, Black Burst house sync
or a 10 MHz reference clock, e.g. from a GPS receiver. The genlock function features passive
loop-through, and has a common timing facility for the generator.
