5850V
NTSC Vectorscope with Electronic Graticule
The perfect mate for the 5860V Waveform Monitor, the 5850V extends
monitoring and timing adjustments into chroma aspects. Accepts a
phase reference from either input (A or B) or from an external reference.
The latter may be composite video, black burst or CW subcarrier. A
unique feature of the 5850V is an electronically-generated scale of
coarse and fine error limits for either 75% or 100% color bars. These
targets allow precise adjustments from relatively large viewing distances
and eliminate the need for fussy centering adjustments. The illuminated
internal graticule facilitates differential gain and phase measurements.
An unblanking input jack on the rear panel accepts a strobe signal from
waveform monitors equipped for line-select operation for vector display
of selected lines.
NTSC Waveform Monitor
The standard workhorse of studio monitoring, the 5860V offers quick
and accurate monitoring of amplitude, time and frequency response
characteristics of composite TV signals. The monitor is equipped with
sweep modes and trigger functions that are optimized for monitoring
video signals. For example, sweep modes 2H, 1H, 1μs/div, 2V, 1V, and 2V
MAG can be selected for the horizontal axis. Optimized filters such as
FLAT, IRE,CHROMA, DIF GAIN and DIF'D STEP can be switched in to
observe various characteristics of video signals. The unit syncs to the
selected A or B feed or accepts black burst or composite sync as an
external reference. An output jack drives a picture monitor with the
selected A or B video feed.
◆ Horizontal sweep mode selection from 1H,
2H, 1μs/div, 1V, 2V and 2V MAG.
◆ Built-in line selector function for monitoring
VITS and VIR signals, a blanking output and a
video output.
◆ Differentiated-step filters easily display the
differential of staircase signals to measure
the linearity of luminance components for
transmission systems.
◆ The frequency response of the vertical axis is
switchable between FLAT, IRE, CHROMA, DIF
GAIN, and DIF'D STEP filters.
◆ K factor scale is provided onscreen for
checking frequency characteristics.
◆ 150mm rectangular CRT with internal graticule can measure without
parallax reading error.
◆ The 5850V simultaneously measures the amplitude and phase of
chrominance components contained in a composite video signal.
To measure phase and amplitude in vector format, the chrominance
components containing color information of the video signal are first
demodulated, and then displayed on the CRT.
◆ VITS and VIR can also be displayed in vector format by applying
blanking signal output from the waveform monitor to the Z INPUT of
the vectorscope.
◆ DP and DG measurements are made using the modulated staircase.
◆ Optional rackmount adapter enables a vectorscope, waveform monitor,
pattern generator, and color monitor to be integrated in a system
