Product Description
TV Eye
Introduced
to
the
world
at
NAB
‘16,
TV
Eye
became
an
instant
hit
with
Visitors
to
the
Murraypro
Booth,
where
it’s
impressive
functionality
coupled
with
compact
format
made
it
an
immediate
attraction.
Housed
in
it’s
bijou
hand
held
case
only
140x120x35mm,
and
weighing
in
at
a
mere
570Gm
(that’s
5.5”x4.5”x1.5”
@
1lb)
TV
Eye
draws
on
the
instant
start
technology
of
Test Chest
(it’s big brother) to fully power up from cold in under 1 second!
Expect
about
1
hour
of
continuous
operational
service
in
‘Eye’
mode
from
the
internal
Li-Po
battery
pack.
Practical
endurance
is
usually
significantly
longer,
as
it’s
boot-free
start
up
means
the
Unit
may
literally
be
switched
‘off’,
conserving
power,
when
not
required
immediately.
The 3.5” LCD panel serves the dual functions of Video monitor and System Control interface.
Confusing ‘soft keys’ are eliminated through use of the TV Eye’s fast & intuitive ‘Touch’ panel
interface, which gently guides Users in their investigations. Despite it’s modest size the screen
provides a bright and clear picture suitable for immediate Engineering requirements, although
of course any assessment of ‘picture quality’ can only be performed using a significantly
larger screen!
Access to the Vectorscope or Waveform monitor is but a screen tap away, and
supplementary display modes are logically presented for instant access.
All of TV Eye’s modes are selected incredibly quickly ~ just a quick tap of the on-screen icon,
and that’s it. No soft keys with which to contend, just a quick intuitive tap of the appropriate
screen icon. Instant reaction, no measurable delay between modes, and even the entire power
up sequence is completed in under a second ~ it really IS that quick!
However, the real jewel in the Crown is provided by the integral “Eye”
monitoring, an unheard of attribute on a product at this price point!
The SDI envelope may be examined over a range of timebase ranging from 3xE, through
10xE for word related artefacts, to Frame rate display to catch picture related issues.
Display may be selected between either the “Raw” unequalised SDI input (vital where the
signal’s wave-shape is being examined for artefacts such as rise/fall asymmetry or overshoot
anomalies with TV Eye located very close to the source equipment); or the “Equalised” SDI
signal where only the original input signal’s ‘zero-axis crossings’ are preserved (this mode is
only pertinent to jitter investigation some distance down a cable, and where the source is not
directly accessible).
TV Eye includes Jitter monitoring too, and the Eye’s display screen includes a dual
histogram which simultaneously displays “Alignment” and “Timing” jitter. The SMPTE specifies
the filter characteristics and the maximum allowable jitter limit for each TV standard, and the
histogram scaling is automatically preset according to the detected standard. The histogram
display, normally coloured green, instantly snaps to a warning red should the jitter exceed the
allowable limit for that source.
TV Eye constantly monitors to ensure that jitter on the input signal does not violate the
SMPTE’s permissable tolerance for that standard, even if ‘Jitter Monitoring’ has not been
specifically selected. In addition to red highlighting on the histogram, the front panel alarm
instantly warns of excessive jitter.
A separate frame rate scan of the selected filtered waveform, showing jitter excursions is
provided for a scope-like display.
A major ‘plus’ too are the automatic measurements performed on the input SDI signal.
Naturally, with all this functionality the audio has not been forgotten and stereo audio
monitoring, selectable across the 16 embedded channels, is provided through the miniature
front panel loudspeakers. For more critical monitoring requirements a completely independent
high quality audio feed is provided for headphone use, which automatically mutes the internal
speakers when they are jacked. Histogram metering with a choice of ballistics and graticule
scaling is provided, and is switchable between 2~16 channel displays.
Includes remote auto-measurement of signal envelope parameters.
