New UDS−2022 * UDS−2021 Series PC−Sampling Oscilloscopes / TDR/TDT

The UDS-2022 and UDS-2021 are the members of the UDS-2000 world Faster Series PC-Sampling Oscilloscopes, which offers the widest range of measurements and waveform processing capabilities of any multi-Gigahertz PC-scope. With excellent measurement repeatability, exceptional vertical resolution and fast display update rate, the UDS-2000 is a powerful measurement tools for semiconductor testing, TDR characterization of circuit boards, IC packages and cables, and high-speed digital data communications. It is a key tool for R&D and production testing.

UDS-2000 instruments are PC-Sampling Oscilloscopes, or oscilloscopes for Personal Computer. They require just USB 2.0 (FS) or IEEE1284 (ECP mode) connector in your PC to give you the computing power of a stand-alone instrument within your PC.

Both models use sequential equivalent-time sampling technology to achieve bandwidth of up to 20 or 12 GHz. Data acquisition and measurement analysis are performed in parallel, enabling the instrument to achieve outstanding measurement throughput. The instruments provide fast acquisition, repeatable waveform performance analysis with automated direct or statistical measurements, Markers and Histograms, Math or FFT analysis, high-resolution TDR/TDT, Color-Graded Display, Parametric Limit Testing, and Mask Template Testing. These measurements can be used independently or in concert.

The GHz-bandwidth and the low-noise specifications allow very precise measurements on low-level, high-speed signals. Time base stability, accuracy, and resolution allow characterization of jitter in the most demanding applications. The instrument provides you with necessary capabilities to test and measure analogue and digital circuits.

The UDS-2000 oscilloscopes are powerful and versatile instruments for waveform analysis in research, development, production, and evaluation testing throughout the telecommunications and data communications industries. The instrument has been designed to give you the highest accuracy, measurement speed, and ease-of-use for characterizing high-speed digital communications waveforms. TDR/TDT is available for optimization of circuit board and transmission lines. Data acquisition and measurement analysis is performed in parallel with PC, enabling oscilloscope to achieve outstanding measurement throughput. The UDS-2000 provides fast, repeatable communications waveform performance analysis with automated pulse and eye-diagram statistical measurements. Electrical conformance tests to define and industry standard eye-diagram masks or pulse templates are easily executed.

Digital Communications Analysis

The UDS-2000 Oscilloscopes designed for communications applications. They provide solutions for design and evaluation of datacomm/telecomm components, transceiver subassemblies, and transmission systems. The UDS-2000 generates measurement results, not just raw data, with time and voltage histograms, mask testing, and statistical pulse parameter measurements. It provides a communications-tailored measurement set that includes jitter, noise, duty cycle, overshoot, undershoot, extinction ratio and amplitude measurements. With the addition of the UDX-R01/R02/R03 Clock Recovery Heads, reliable parametric testing up to 2.7 Gbps bit rates becomes easy even when you do not have access to a clock signal trigger.

Accurate eye-diagram analysis for NRZ and RZ signal types is essential for characterizing the quality of electrical and optical transmitters to beyond 10 Gb/s. The UDS-2000 were designed specifically for the complex task of analyzing digital communications waveforms. Compliance mask and parametric testing no longer require a complicated sequence of setups and configurations. The important measurements you need are right at your fingertips, including industry standard mask testing with built-in margin analysis, extinction ratio measurements with improved accuracy and repeatability, automatic eye measurements: crossing %, eye height and width, one and zero levels, jitter, rise or fall times and more. In addition, mask testing of SDH/SONET, and other standards simplifies compliance testing. A full color display helps you to discriminate waveform details. A color-graded display mode adds a third dimension - sample density - to your signal acquisitions and analysis.

TDR and TDT

The UDS-2022 and UDS-2021 can be configured as a single-ended time-domain reflectometer. The step generator provides a >400 mV TDR step with typical system rise time of 100 ps. The system has the ability to normalize the TDR by applying a digital filter. Normalization removes errors caused by loss or imperfect launchers or cables. The rise time of the normalization filter may be varied to allow you to simulate the edge speeds found in your system. You may also push the rise time up to 10 ps. The vertical scaling allows scaling in volt, percent reflection or ohms. The horizontal scaling allows scaling in time or distance. Distance measurements are subject to the accuracy of the propagation velocity or dielectric constant that you enter. Cursors will also read in voltage, percent reflection, ohms, time or distance.

Familiar Windows-95/98/ME/NT4/2000/XP User Interface

The UDS-2000 Oscilloscopes have a Windows intuitive graphical user interface, so you won't have to spend a lot of time learning or relearning the instrument. Pull-down menus give you easy access to advanced features and icons provide quick access to an extensive set of common tests and measurements.

Built-in Information System

The UDS-2000 Oscilloscopes have a built-in information system that puts measurement assistance at your fingertips. You'll no longer have to look for the manual when you need help setting up the oscilloscope or making complex measurements. A measurement set-up guide gives you step-by-step instructions for many measurements and procedures. Links on the measurement screen take you directly to the information you need in the on-line manual.
