Applications:
- Cost-effective Signal Monitoring in Camera Control Consoles
and Video Transmission Applications
The Tektronix 1720 Series Vectorscopes
provide comprehensive television signal monitoring for both NTSC and PAL
applications. These Versatile instruments are light weight,
half-rack width and have bright CRTs for video signal monitoring.
Both Instruments exceed normal monitoring capabilities, and there unique
features make them even more powerful when operated in tandem.
Each monitor has its own advanced feature set and the proven 1700 Series
family performance to provide more monitor for the money. These
monitors do the job faster, better and easier at an economical price.
The 1720 series and
1730 series families cover a wide variety of video
testing needs. For typical composite monitoring in the NTSC and
PAL realm, the 1720 series and 1730 series more then handles the job.
If there is a need for PAL and NTSC standards,
the
1735 Waveform Monitor
and 1725 Vectorscope can be used. Digital testing of both
composite parallel and composite serial can be accomplished with the
1730 series of Digital Waveform Monitors. Whatever the individual
video testing application, the 1720 and 1730 series family provide an
easy to use, economical solution.
Complete Line Select
The 1730 Series Waveform Monitor has full
frame line select, with alphanumeric readout, that can be tracked by the
1720 Series Vectorscope when in Auxiliary mode. Any one or two
lines of the entire frame can be selected and displayed or the same
line(s) in both fields can be viewed at one time. An intensified
zone in the two-field sweep and on the picture monitor output signal
indicates the location of the line selection. In addition, any
successive 15 lines can be overlaid for camera and VTR adjustments.
Simultaneous Channel A and B Display
These instruments have
microprocessor front panel control. They are operator-friendly and
provide outstanding features in half-rack waveform monitors or
vectorscopes. Both the
1730 Series Waveform Monitor and
The 1720
Series Vectorscope has dual channel display capability, allowing both
input channels to be displayed on the CRT simultaneously.
One-Button Front Panel Recall
Once the front panel has been set
up in a frequently used mode, the configuration can be stored for later
one-button recall. In addition, when the 1720 is used in tandem
with the 1730, it will respond to this Store/Recall operation. Up
to four operator-selected front panel configurations can be stored front
the front panel. Four other front panel configurations are
factory-programmed settings and are accessible from the remote control
interface

Differential Phase and Gain Measurements
The 1720 Series Vectorscope
graticule has scales for measuring Differential Phase and Gain.
The Differential Phase scale has markings at 2° intervals. The
Differential Gain scale has markings at 5% intervals. For even
greater precision, the 1720 and 1730 series can be coupled for
differential phase measurements using the field or line sweep on the
1730 series Waveform Monitor. The Waveform Monitor Chroma filter
can be used for differential gain measurements.Stereo Audio Phase Measurements
Balanced inputs for the XY mode are available on the 1720 series
Vectorscope through a separate input connector. This mode is
particularly useful for evaluation of stereo audio with a special XY
graticule scale for both amplitude and phase measurements. XY
measurements can be displayed individually or in combination with a
vector display. This input can also be used for other applications
where XY monitoring is useful.
RGB-YRGB
The Waveform Monitor can display RGB or YRGB. The RGB/YRGB
staircase input in through a rear panel connector
Vector Center Dot Clamping
The 1720 Series Vectorscopes employ center dot clamping in Vector
mode for easy detection of residual sub-carrier on the signal. In
Addition, with no signal present, the center dot automatically dims
prolonging the CRT life.
Parallax-Free Internal Graticules
Both instruments utilize post-accelerated, mesh-type CRT's equipped
with internal graticules to provide parallax-free displays.
Variable, evenly-illuminated scales, along with molded bezels, make
waveform photography a snap
Remote Control
Internal front panel presets, RGB/YRGB enable, along with front
panel recall/setup can be accessed through the waveform monitor remote
connector. |
