Diagonal r Internal Memory for 20 Waveforms and Notes r Serial Printer Output for Stored or Displayed Waveforms   The GT20 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 expore faults that have been previously invisible to TDR yet still an impairment to digital signals. The GT20 also introduces one-button testing. Testing at Higher Bandwidth Because the GT20 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 GT20 has the bandwidth to enable you to find problems that may exist only at higher frequencies. High SNR The GT20 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 GT20. This means that you can clearly see faults further away. High-resolution performance allows the GT20 to locate problem components in the customer drop. The GT20 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. But the most innovative feature in the GT20 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 GT20 the only logical choice for digital services. The GT20 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 GT20 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 GT20 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.           Specificaties           Test Signal Output: 1/2 sine     Amplitude (into 75 Ohm): 4 V into 75 Ohm     Pulse Widths: 1 ns, 5 ns, 25 ns     Output Impedance: 75 Ohm     Acquisition System Bandwidth: 400 MHz     TestWizard Testing: Automatically marks faults.
