User-installed, Oscilloscope-resident Timing Analysis Package

TDSJIT3 is the premiere jitter and timing analysis software package available for real-time oscilloscopes. Running externally or within the Tektronix DPO7000, DPO/DSA70000, TDS5000B, TDS6000B/C, and TDS/CSA7000B Series oscilloscopes, TDSJIT3 provides the highest accuracy and lowest noise jitter measurements available in any real-time instrument. With comprehensive jitter analysis algorithms TDSJIT3 simplifies discovering jitter and its related sources in today's high-speed digital, communication, and system designs.

Digital designers, analog designers, communication and systems engineers in the computer, semiconductor, and communications industries are facing new challenges as processor clock speeds race beyond 3 GHz and backplane electrical data rates greater than 6 Gb/s become commonplace. These increasing clock and data speeds mean reduced circuit tolerance, or margin, for noise and jitter. By using tools to rapidly characterize and discover sources of jitter, designs can be made more robust, brought to market faster, and ultimately operate better in today's ultra high-speed environment.

Measurements

*¹ Features are only available with TDSJIT3 Advanced.

The TDSJIT3 Jitter Analysis Software extends Tektronix’ real-time oscilloscopes capability, performing complex measurements on contiguous clock cycles or data edges single-shot acquisitions. Providing jitter measurements for most key timing parameters required by today’s interface standards, TDSJIT3 Advanced and TDSJIT3 Essentials are specifically designed to meet the jitter measurement needs of today's high-speed digital designers in the computer and communications industries. Measurements can be made on differential signals, between two separate inputs, or on multiple inputs simultaneously. Multiple measurements and plots can be displayed on the internal and external monitor. Trend analysis plots quickly show how timing parameters can change over time, like frequency drift, PLL startup, or response to power supply changes. Spectrum analysis quickly shows the frequency of jitter and modulation sources for easier identification: adjacent oscillators and clocks, power supply noise, or signal crosstalk. Comprehensive statistics and histograms of timing parameters enhance the powerful analysis capabilities of TDSJIT3 Plot displays and data can be relocated to the second monitor, saved to disk, or exported for further analysis. Acquired waveforms and measurement data logs can be saved for later analysis. You can quickly make accurate total jitter (Tj) estimates at levels down to 1×10^-18 BER on common data signals including those with random pattern content. Control population size across single or multiple acquisitions; qualify what part of a signal is measured; correlate jitter trends and peaks to the original acquisition waveform; even share and analyze stored waveforms captured by colleagues.
