Colour pattern generator GV-698+
5 DESCRIPTION OF INPUTS AND OUTPUTS
5.1 Composite video output (BNC)
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
The modulated RF output is achieved througt the RF connector
front panel.
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 50 dB in steps of 10 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).

By means of the SYNC-LOGO-SCART configuration menu, it is possible tu
insert synchronisms in the G/Y output and selectioner RGB or YP
5.5 S-VHS output
This is via the 4-contact socket
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.
