The TEKTRONIX 1730-Series is an 8-1/2-inch wide by 5-1/4-inch high
waveform monitor, weighing approximately 8 pounds. The 1730 (System M,
NTSC) and the 1731 (System I, B, etc., PAL, PAL-M), and the 1735 (dual-standard) versions can be powered from an ac source or, with the addition of a field
upgrade kit (1700F10), 12 Vdc. The CRT occupies approximately two-thirds of
the front-panel area, with the control panel taking up the remainder of the space.
Operation is controlled by a microprocessor that polls the front-panel switches
and remote ground closures. Front-panel switches are of the momentary touch
type with lighted functional indicators. Most of the switches are also used to
select special functions, which are accessed by holding the switches in until the
microprocessor recognizes the request.
The signal is displayed on a bright CRT capable of displaying one line per frame.
It is of the mesh type, for better geometry, and uses an internal graticule to
reduce parallax. Variable graticule scale illumination provides even lighting to
improve measurement accuracy and the quality of waveform pictures. Option 74
provides a P4 (white) phosphor tube.
The Channel A and B Composite Video Inputs and the External Reference
Signal Input are high impedance bridging loop-throughs, in order to protect the
integrity of the signal paths. The input switching allows for the display of either
Channel A or Channel B Input or both inputs. Synchronization can be either
internal or external, with the further choices of using remote sync or 90 or 100
Hz synchronization, from a VTR, where the application warrants.
The 1730-Series offers a choice of three basic sweep rates: 2 Field, 2 Line, and
1 Line, each of which can be magnified to provide three additional sweep rates:
1 ms (2 Line), 0.2 ms (1 Line), and X25 (2 Field) which provides for viewing the
complete vertical interval. In addition, there is full frame line selection that can
be displayed as 1 line, 2 lines, or 15 lines. A bright-up pulse, for picture
monitors, that corresponds to the intensified region on the CRT display, is
available through a rear-panel bnc connector.
The vertical signal processing provides a choice of fast or slow dc restoration, or
an unclamped display. The input signal can be unfiltered (Flat) or either Low
Pass or Chrominance filtered. There is also a combination of Flat and Low Pass
filtering available when a 2 Line or 2 Field sweep rate is employed; the display
consists of one line or field low pass filtered while the second is unfiltered.
Vertical amplitudes can be displayed in a calibrated gain mode, which corresponds directly with the graticule vertical scales, magnified 5 times, or can be set
to a specific amplitude by using the Variable GAIN control.

1730–Series Introduction
An RGB or YRGB Parade display, for camera setup, is accommodated with a
shortened sweep. The input of the camera signal and an enable are through the
rear-panel REMOTE jack. The choice of 3-step (RGB) or 4-step (YRGB) is
made by changing the position of an internal jumper.
The 1730-Series has a unique Store and Recall function built in that allows for
the storing of up to four front-panel setups that can be recalled by pressing the
appropriate recall button, or a ground closure through the rear-panel REMOTE
connector. In addition, four factory-programmed measurement setups can be
accessed, by external ground closures input through the REMOTE connector.
An auxiliary output, to control a companion 1720-Series Vectorscope, is
provided through a rear-panel connector. The auxiliary output contains a bus for
two-way communications between the waveform monitor and vectorscope
microprocessors and a strobe to provide line select unblanking for the Vectorscope.
Typical Configurations
The 1730-Series Waveform Monitor is designed for operation either alone or
with a 1720-Series Vectorscope. Line select and measurement recall for this
waveform monitor are also used by the vectorscope. Because of these capabilities, and the available 90 or 100 Hz triggering, the 1730-Series Waveform
Monitor is ideally suited to operate in a VCR bridge. With its factory-preset
measurement routines, that can be accessed through the rear-panel REMOTE
connector and the Store/Recall functions, it is possible to have one-button
measurements of key parameters, including various vectorscope measurements.
In addition to the VCR bridge and the typical Master Control monitoring
applications, this monitor can be used in camera chains. It has a choice of RGB
or YRGB Parade display that can easily be selected by changing one internal
jumper setting. The Parade signal and enable are input through the rear-panel
REMOTE connector.
A number of operating conditions can be altered by changing internal jumpers,
using some of the factory-preset combinations, or setting up and saving the front
panel with the Store/Recall function. Using these methods most of the current
528A operational modes can be accommodated. There is a difference in how the
remote control operates — the 1730-Series uses ground closures, not positive
voltage as the 528A did.

1730–Series Introduction
Safety Information
Specification
The 1730-Series is intended to operate from an ac power source that will not
apply more than 250 V rms between the supply conductors or between either
supply conductor and ground. A protective ground connection by way of the
grounding conductor is essential for safe operation (except for those instruments
that are operated from a battery supply).
The 1730-Series was tested for compliance in a cabinet. To ensure continued
compliance, the instrument will need to be enclosed in a cabinet that is equivalent to the Factory Upgrade Kits that are listed as Optional Accessories for the
1730-Series. A drawing of the 1700F00 plain cabinet is contained in the
Installation Instructions (Section 3).
In the specification tables that follow, some items are identified as performance
requirements. These can be verified by performing the Performance Check
Procedure in Section 5. Not all performance requirements have a measureable
tolerance, and therefore do not have a performance check step; however, they are
either verified by indirect means, through other portions of the procedure, or are
design criteria that do not need to be tested for individual instruments.
Whenever there is a verifiable performance requirement, in the specification
table, there will also be a reference to identify the location, in the Performance
Check Procedure, of the appropriate performance verification procedure.
The supplemental Information designation in the tables indicates that this is
information that either amplifies a performance requirement or is special
information that is of importance. Unlike performance requirements, there is no
need, and often no way to check these items to any specific tolerance.

Typically the internal environment inside a product is considered to be the same as the external.
Products should be used only in the environment for which they are rated.
Pollution Degree 1No pollution or only dry, nonconductive pollution occurs. Products in
this category are generally encapsulated, hermetically sealed, or
located in clean rooms.

temporary conductivity that is caused by condensation must be

Temporary condensation occurs only when the product is out of
