Model 2901C is designed for
testing faults on coax, twisted
pair, or any metallic paired
cable, whether it be aerial or
underground. Model 2901 C can
be used to troubleshoot cable
installations or to measure
cable on the reel.
Model 2901C is a medium
range cable fault locator used
to locate opens, shorts, bad
splices, bridged taps, load coils,
bad connectors, sheath damage,
water problems, or other
major problems in all sizes and
types of cable, all without sacrificing
accuracy.

The TDR can be used to:

Locate anomalies caused by wiretaps or bugging devices
Locate bad splices
Locate unknown splices
Find in-line components
Locate water or moisture in the cable
Aid in measuring and verifying new or partial cable reels
Locate crushed, pinched or kinked cables
Locate opens and shorts in the cable
Locate bullet holes or damage in the cable
Measure dBRL (decibels of return loss) of the fault
Locate problems caused by construction companies
Use to document the integrity of your cabling
Use to document or map cable networks
Locate problems causing excessive loss of either AC or RF
Document cable installations prior to acceptance from the contractor
...and a variety of other cabling problems.

The Riser-Bond Instruments waveform TDRs come equipped with unique signal filters for cleaning up noisy waveforms.

It is not always possible to completely disconnect the cable under test from all other equipment. A couple of examples of this are a tower cable that goes into an antenna, or a local area network that needs to stay operational during the test.

If the cable is left attached to equipment at the far end, the energy present on the cable may present a danger to the operator o to the TDR. If so, do not proceed with the test until danger is removed. A TDR may damage the equipment on the cable under test. Riser-Bond Instruments TDRs test using a negative voltage signal of less than five volts in amplitude and with varying pulse widths. The amplitude should not damage any equipment on the cable. However, excessive pulse width may cause a digital system to adversely react to the TDR signal.

There are many different types of signals that can be present on the cable under test. They range from 50/60 Hz power, to audio frequency, to data in the 1 to 100 MHz range, to RF. No single filter will eliminate all of these signals. Riser-Bond Instruments waveform TDRs have multiple types and levels of software filters which can eliminate almost any type of problem. In a filtering application, it is necessary for the operator to step through the various filters to see which one will work best in any given application.

Because of the inherent nature of the filters, some operate so fast they do not seem to affect the speed of the instrument display, while others seem to slow the display so much that it makes display manipulation almost impossible. An example of this is filtering power line noise. A 50 Hz power line cycle takes 20 milliseconds to complete and therefore 20 milliseconds for the TDR to create one screen display dot. The update rate of a 256 dot display would then be over two seconds. This is a long time when trying to reposition a waveform. One way around these long delays is to turn on the filter that will do the most good, then simply store the filtered waveform . Waveform storage may take a long time, but the post-storage waveform manipulation will be as fast as having the filter turned off.

When testing data cables that are remaining operational, it is best to keep the TDR in a short pulse width mode, like 2, 10, or, at the very most, 100 nsec. This way, the error detection software of the data system will not see the pulse as "bad data" and continually request for "resend data" which may lock the system.

The TDR noise filters are extremely useful when testing noisy cable but, as with any equipment, experience will enhance success. Practice with different noise sources using different filters.
