The TV220 delivers high performance, yet is so easy to use that little or no
training is required. This leading edge TDR can test more system bandwidth and
expose faults that have been previously invisible to TDR yet still an impairment
to digital signals. The TV220 also introduces one-button testing.
Testing at Higher Bandwidth
Because the TV220 tests at a
high bandwidth (it uses a 400 MHz acquisition system), it tests more of your
system capacity. This enables users to pinpoint more faults that can cause
micro-reflections which can degrade digital transmission BER. Only the TV220 has
the bandwidth to enable you to find problems that may exist only at higher
frequencies.
High SNR
The TV220 also has extremely high
signal-to-noise ratio (SNR). Tempo proprietary circuit designs reduce the noise
level so that "bumps" on the trace represent real faults, not just noise. Events
that were previously difficult or impossible to find are clearly visible
(because the noise is much lower) with the TV220. This means that you can
clearly see faults further away.
High Resolution
High-resolution performance allows the
TV220 to locate problem components in the customer drop. The TV220 uses a pulse
width of only 1 ns which means the operator can clearly identify multiple events
that are less than 2 feet apart. This enables the technician to tell which of
two components on a cable is causing the problem, even when they are close
together. This is particularly important in troubleshooting drops, because
components such as splitters and ground blocks can be very close together.
TestWizard Testing
But the most innovative feature
in the TV220 is TestWizard automated testing and event marking. Now, instead of
meticulously setting up the TDR and then carefully interpreting the meaning of
the displayed waveform, you push one button to get a high-resolution, low-noise
trace, with the events clearly marked. This means substantial savings in
training time and reduced time to get accurate, repeatable measurements.
The Only TDR for Digital Services
High bandwidth, high
resolution, high SNR and ease of use make the TV220 the only logical choice for
digital services. The TV220 tests more of the capacity of your cable, finds
faults that are closer to the ends and finds faults that are closer together
than any other TDR available.
CableScout TV220 Helps Solve Tough Problems
Any TDR
can find a break or major problem, but what about those small nagging cable
faults that keep your system from running smoothly CableScout TV220 can find
those really tough-to-identify problems, and it is easy (see examples below). A
high performance TDR does not have to be difficult to use. This one makes even
the first time user look like a pro.
The TV220 - Designed for You
If your job is to maintain
or find faults on coaxial cable, the Tempo CableScout TV220 is built for you.
With the TV220, you'll spend less time operating the instrument and more time
analyzing and repairing faults.
You know the problems we're talking about - the annoying small ones that
cause a 3 dB notch near the upper end of your bandwidth. Now you can accurately
locate them - fast and easy.
You get all this performance in the industry's most rugged TDR package. Come
snow, rain, heat, humidity, dead of night or untrained user, Cable Scout TV220
keeps working, because you have to.
