Hantarex MTC 9000 User Manual

INTRODUCTION
The
principal new
features of the
MTC 9000
are as follows:
•
All the
controls
which
directly affect the
display,
horizontal frequency,
vertical frequency,
vertical amplitude, horizontal
amplitude,
horizontal phase
and
vertical shift, are
mounted on a small printed circuit board connected to the main
board by
a
connecting
cable.
The
monitor
Is supplied
complete with a
connecting cable 1.5
metres long, which permits the remote mounting
of
the
control board
in the
most
convenient
position for any particular
application.
This
"remote"
feature is
exciusive to
the
Hontorex MTC 9000.
•
Addition of two
connectors to
each
deflexion yoke with
inverted connexions which,
by
choice of connector, permits
the easy
inversion of the
Image
both vertically
and horizontally
for certain applications.
•
Introduction
of a
novel
circuit into the
power supply,
which, at an excessive drop in supply voltage, transforms the
stabilizer
circuit
into an
anti-ripple
circuit so
permitting the use
of the monitor outside the limits
of
stabilization.
•
Use
of a
special
three-position
switch in the video
input
circuit
using
close tolerance resitors, permitting
the monitor
to
be
connected to
input
signals
varying between 2
and 5 V
p.p.
without
the introduction
of tracking errors, which
would
otherwise
cause
undesirable
colour changes.
•
Introduction
of a
new
integrated
circuit (TDA
1670]
for vertical deflexion which permits the achievement of
a
short
vertical
fly-back time
(0.9
ms),
and extends
the use of the
monitor where a short vertical blanking period is required.
•
introduction
of a new
integrated
circuit in
the
horizontal oscillator synchronization circuit, which, among
other things,
provides
for more
accurate
intervention of the x-ray
protection circuit as
required
by the principal international safety
standars,
such as
F.D.A., the
Federal Drug
Administration.

NOTE (a):
The
MTC 9000 is
provided
with both
horizontal and
vertical blanking signals, which
permits
the use of the monitor with
signals
without blanl<ing.
(b):
The three
RGB video
amplifiers are d.c.
coupled: there
is thus no lower limit to the pass band.
