Introduction
Product Description
The 1760--Series Component Waveform/Vector monitors
display component signal channels two ways: in parade and
overlay modes and as component color vectors. A component picture monitor output is provided for display on an
RGB monitor.
The 1760--Series monitors feature the Tektronix Lighting
display. This display indicates everything needed to adjust
setup, video gain, chroma gain, and interchannel timing for
standardized playback of component video recordings.
In addition to component monitoring, all the composite waveform and vector monitoring capabilities of the 1740A--Series monitors are included in the 1760--Series monitors.
The following products are available:
The 1760--Series monitors can also be ordered with an SCHphase option (see page 1-5).
Applications
Typical applications for these half-rack size monitors include
video signal monitoring in camera control units,
production switcher consoles, mobile vans (“OB” vans in
Europe), and field production systems.

filters in addition to flat.
CRT
The monitors have a bright, post-accelerated CRT with
lighted internal graticule. The parallax-free internal graticule
structure contains targets and markings for both the vector
and waveform functions. A white phosphorus CRT is optional; refer to page 1-6 for details.
The bright CRT allows use in high ambient light conditions,
such as those encountered in field production applications.
Calibrator
Vertical and horizontal instrument gain can be set using the
calibrator signal. The 1 Volt calibrator signal is available in
100 kHz and F

phase relationship. It includes the same SCH capabilities as
the 1750A--Series instruments.
Power Cord Options
Any of the following power cord options can be ordered for
the 1760--Series. If no power cord option is specified, instruments are shipped with a North American 125 V power cord
and one replacement fuse.
Unless otherwise specified, power cords for use in North
America are UL listed and CSA certified. Cords for use in
areas other than North America are approved by at least one
test house acceptable in the country to which the product is

1700F00 Plain Cabinet — This plain metal half-rack size
cabinet is painted silver-gray. Ventilating holes in top,
bottom, and sides of the cabinet allow heat generated within
the instrument to dissipate.
1700F02 Carrying Case — This portable cabinet is
similar to the 1700F00, but has feet, carrying handle, flipstand, and front cover.
1700F05 Side-by-Side Rack Adapter — The 1700F05
allows the user to mount two half-rack width instruments in a
standard 19--inch rack.
1700F06 Blank Panel — If only one section of a 1700F05
is used, the 1700F06 Blank Panel can be inserted in the
unused section to improve appearance and air flow.
1700F07 Utility Drawer — When only one side of a
1700F05 is used, this utility drawer can be installed in the
unused section to provide storage. The drawer opens and
closes freely, unless latched for transport.
Ordering — These items can be ordered with the monitor,
or purchased through a Tektronix field office or distributor.
When ordering, include both the name and number of the
Field Upgrade Kits.
Installation — Cabinet installation instructions begin on

cabinet. For more information, contact a Tektronix field
office or distributor.

Unpacking
Save the shipping carton and packing materials (including
anti-static bag) in case it becomes necessary to ship the
instrument to a Tektronix Service Center for service or repair.
Accessories
Check that the following accessory items are included:

Packaging for Shipment
If you ship an instrument to a Tektronix Service Center, follow these packaging instructions:
1. Attach a tag to the instrument showing: the owner,
complete address and phone number of someone at your
firm who can be contacted, the instrument serial number
and a description of the required service.
1760 Series Component Waveform/Vector Monitor User Manual 1-9
Installation
2. Package the instrument in the original packaging materials. If the original packaging materials are not available,
follow these directions:
a. Obtain a carton of corrugated cardboard having
inside dimensions six or more inches greater than
the dimensions of the instrument. Use a shipping
carton that has a test strength of at least 275 pounds.
b. Surround the instrument with a protective bag
(anti-static preferred). If the instrument is not in a
cabinet, wrap a cardboard pi ece around the bagged
instrument to protect components.
c. Pack dunnage or urethane foam between the instru-
ment and the carton. If using Styrofoam ke rnels,
overfill the box and compress by closing the lid.
There should be three inches of tightly packed
cushioning on all sides of the instrument.
3. Seal the carton with shipping tape, industrial stapler, or
both.
Electrical Installation
Power Source
These monitors are designed to operate from a single-phase
power source having one of its current-ca rrying conductors at
or near earth ground (the neutral conductor). Only the line
conductor is fused for over-current protection. Systems that
have both current-carrying conductors live with respect to
ground (such as phase-to-phase on multiphase systems) are
not recommended as power sources. A protective ground
connection by way of the grounding conductor in t he power
cord is essential for safe operation.
