COLOUR PATTERN GENERATOR
GV-698+
1 GENERAL
1.1 Description
The GV-698+ colour pattern generator is used for control and measurements,
maintenance and repair of TV and video equipments. Its application areas are
development, quality control, TV production studios, service workshops and training.
This instrument covers the frequency range from 35 to 900 MHz, with Vestigial
Side Band modulation.
It generates digitally 16 basic pattern charts, which extend to 22 when pushing
repeatedly the chart keys.
The GV-698+ incorporates WSS signal (Wide Screen Signaling) in 8 formats,
FLOP-TELETEXT in four languages and VPS and PDC signals for four countries. All
these signals are individually selectable.
It also provides a synthesised sound modulator for all the systems previously
described. Besides it incorporates the ZWEITON stereo-dual system in B/G/D/K/M
format and NICAM in B/G/I/L format.
It incorporates 32 memories where different configurations may be stored for a
later easy access by means of the rotary selector. All the configurations can take
control of the combination of the rotating selector and the keyboard, visualizing in
display alphanumeric of two lines.
The RF signal can be selected by channel or by frequency, in 50 kHz
increments and to attenuate it 50 dB in 10 dB steps. Channel/frequency and
attenuation information is shown on the graphic display.
It also includes video output, SCART connector, S-VHS connector, output for
complete synchronism, output for RGB switchable to Y Pb Pr signals with possibility of
adding synchronism on green (Y) or on luminance signals and It’s also available a
connector for remote control with the RS-232C bus.

field flashes and if then encoder is turned it hops through the different options of this
field. Once we have selected the desired value we push the encoder; then we can start
a new selection.
If it is desired to store the new configuration, we will turn the encoder until
selecting MEMORY field. Next we will push the encoder until hearing a beep, in the
display will appear the memory number and a question 00?, we will turn encoder until
obtaining the number of memory that we wish (0 to 31) and will push the encoder to
store it. With this operation we will have stored in the selected memory all the
parameters of the generator, as much those of the display as the position in which are
all the keys of the generator.
MEMORY
Shows the active memory position. At start up the initial position is 00. In order
to activate another memory this field has to be selected with the encoder and
then press it (the first digit will flash). In this situation we can change of memory,
turning the encoder and pushing it to confirm it is the memory that we wished. If
we maintain the pressure until a beep is heard we will be able to store the
configuration that we have in another value of memory.
COLOR
Selection of the colour system among PAL, SECAM and NTSC.
SYSTEM
Selection of the television system among B / G, I, D / K, L, M and N.
SOUND
Selection of the sound system among MON (monophonic), NIC (NICAM), ZWE
(Zweiton), EXm (outer mono), EXz (outer Zweiton) and OFF (without sound
carrier), according to selected standard.
ATTENUATOR
Il selects the attenuation of the RF signal in 10 db steps between 0 and 50 db.
CHANNEL
Selection of the tuning mode between tuning by frequency FREQ and tuning by
channel, in this later case the display will show the name of the Channel Set
CCIR, STDL, OIRT or FCC (based on the stored Stes, see appendix A).
CH-FREQ
Selection of the RF frequency output. In the mode of tuning by east frequency
parameter can vary between 37 MHz and 865 MHz in 50 progressive jumps of
KHz. In the mode tuning by channel it appears the name of the channel.

5 DESCRIPTION OF INPUTS AND OUTPUTS
5.1 Composite video output (BNC)
[11]
The composite video output is achieved through the VIDEO connector
on the front panel. The polarity of the signal is positive, the black level being 0 V. The
output level is fixed to 1 Vpp. This signal is very useful in testing B/W and colour video
monitors, linear amplifiers, VCR or any other equipment which operates with a
composite video signal.
CAUTION
This signal must not be connected to any live point in a circuit, but
only to normalized video inputs of 75 Ω impedance. Any damage
produced in the equipment due to non-observation of this precaution
is not covered by the guarantee.
5.2 Modulated RF output
[9] on the
The possibility of attenuating the RF output has been foreseen for testing the
automatic gain control circuits and the sensitivity of television sets: permitting a total
maximum attenuation of 60 dB in steps of 1 dB.
5.3 Synchronism output, vertical pulse and horizontal pulse
The GV-698+ has one synchronisms output situated on the rear panel: CS [12]
composite synchronism output (horizontal and vertical).
5.4 R-G-B/ Y Pb Pr output
The R-G-B/Y Pb Pr outputs are situated on the rear panel, through three BNC
sockets R Pr [13], G Y [14] and B Pb [15], respectively.
By means of the SYNC-LOGO-SCART configuration menu, it is possible tu
insert synchronisms in the G/Y output and selectioner RGB or YPbPr output.
5.5 S-VHS output
This is via the 4-contact socket
[18] on the rear panel.
Separate luminance and chrominance outputs used in the S-VHS system are
available. Their use as a high quality video standard is becoming more and more
widespread and the quantity of television sets and video equipment incorporating them
is increasing.

7 REMOTE CONTROL COMMANDS
The GV-698+ has incorporated the same type of remote control that was
designed for the PROLINK-1 and 7. The transference procedure is based on protocols
XON-XOFF and ACK-NAK, through a RS-232C port series working at 19200 bauds, 8
bits, none parity and 1 stop bit.
On this structure, executive and interrogatory commands, are transmitted to
allow of changing the equipment configuration or operation or, to interrogate about its
state.
The commands are the base to implement the remote control of the equipment,
that allows so much the automatization of some processes, like the generation of
control application by the end user.
The equipment dispatches the received commands through the port series on
automatic mode, with no need any special type of action from the frontal panel. The
commands available are extended in each version, according to their necessity.
At this moment, for firmware 2.12 version, the available commands are those
indicated in the following table:
