:
Using TDRs in CATV applications is a 25-year-old story with a new chapter – the CableScout® TV220. Formerly, TDRs have been
viewed as complicated and expensive. The CableScout TV220 changes all that. It delivers greater performance, yet is so easy to
use that little or no training is required. This leading edge TDR can test more system bandwidth, find faults that were previously
invisible to TDR, and introduces one-button testing.
Testing at Higher Bandwidth
Because the TV220 tests at a higher bandwidth (it uses a 400 MHz acquisition system) than any other TDR, it tests more of your
system capacity. This enables users to pinpoint the faults that can cause micro-reflections which can be damaging to digital transmissions. 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). 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’re 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’s easy (see examples below). A high performance TDR doesn’t 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 new 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,
CableScout TV220 keeps working, because you have to.
The Advantage of High Bandwidth and High SNR
The two displays below demonstrate the
TV220 advantage. Both traces were
taken on the same cable which had a
small amount of sheath damage. This
type of damage affects only the perform-

ance of the higher channels in a CATV
system. The trace on the left (measured
with the TV220) clearly shows the damage located at 398 feet. The second
trace on the right (measured with another
TDR) doesn’t show the event.
Typical TDR test misses the fault completely.
TestWizard™ Testing: Automatic One-Button Testing
TestWizard™ Testing automatically finds multiple faults on coax cable. There’s no longer a
need to interpret the results; they’re clearly
marked. TestWizard testing automatically
adjusts and optimizes gain, averaging, and
pulse width to provide the best possible resolution while maximizing the instrument’s ability
to find all the problems on your cable – even
small problems missed by most other TDRs.
All you do is press the yellow TestWizard button, select the cable type, length, and number
of events to display; then view the results. If
you want to measure the Return Loss of an
event, simply jump the cursor to the event,
and CableScout TV220 automatically reports
the Return Loss. Technicians no longer have
to be afraid of erroneous or unreliable results
with a TDR. CableScout TV220 with
TestWizard testing makes every user an
expert!
