1730–Series Introduction
1–2
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 Vector-
scope.
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 capabili-
ties, 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.
