Product Description
The Tektronix 1710J-Series is a specialized oscilloscope. It is designed to
monitor and measure baseband video signals. It offers a choice of three basic
sweep rates: two field, two line, and 1 line, each of which can be magnified to
provide three additional sweep rates, 1
m
s (two line), 0.2
m
s (1one line), and X25
(two field). The two-field sweep rate, both magnified and unmagnified displays
the complete vertical interval.
The Channel A and B Composite Video Inputs and the External Reference
Signal Input are high impedance bridging loop-throughs to protect the integrity
of the signal paths. The input switching allows for the display of either Chan-
nel A or Channel B Input or both inputs. Synchronization can be either internal
or external.
The vertical signal processing provides slow DC restoration that clamps the
display while still showing any 50 or 60 Hz hum components. 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 five times.
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 connector. The choice of three-step (RGB) or four-step
(YRGB) is made by changing the status of a control line through the REMOTE
connector.
The CRT is a mesh type, which has better geometry. In addition, it 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.
