Product Description

The UDS-2214 is a member 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.

The UDS-2214 includes two TDR channel. Each of the TDR channel may be equipped with any of four external Pulse Heads. Combination of dual-channel 14-GHz sampling oscilloscope and two pulse generators gives possibilities of Single-ended, Common or Differential TDR/TDT.

With excellent measurement repeatability, exceptional vertical resolution and fast display update rate, the UDS-2214 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.

The UDS-2214 is PC-Sampling Oscilloscope, or oscilloscope for Personal Computer. It requires 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.

The UDS-2214 used sequential equivalent-time sampling technology to achieve bandwidth of up to 14 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 multi-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.

TDR and TDT

The UDS-2214 can be configured as a Single-ended, Common or Differential TDR/TDT.

It can be equipped with any of the UDX-G11/-12/-13/-14 Pulse Heads. Each of the head is a single-ended pulse head providing fast and flat pulses having both polarities, rise time of 100 ps and flat transient response.

The UDX-G11 and UDX-G13 are TDR/TDT Loop-through Heads having 400-mV pulse amplitude, while the UDX-G12 and UDX-G14 are TDT Heads having increased 2-V pulse amplitude.

Different configurations of the heads provide single-ended, common and differential TDR/TDT measurements.

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.

Digital Communications Analysis

The UDS-2214 Oscilloscope is designed for communications applications. It provides solutions for design and evaluation of datacomm/telecomm components, transceiver subassemblies, and transmission systems. The UDS-2214 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-2214 is 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.

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

The UDS-2214 has 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-2214 has 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.
