User-installed, Oscilloscope-resident Timing Analysis Package

Electronic design engineers in semiconductor and communications industries develop systems with high clock speeds and reduced timing margins. As clock frequencies in the industry continue to increase, timing margins become more critical. Sophisticated techniques are required to properly characterize the placement of these clock and data edges. Customers in these industries need to ensure that the timing margins in their designs are not violated because of excessive jitter.

The TDS7000 oscilloscopes have superb jitter analysis capabilities on non-contiguous clocks with their histogram and statistics capabilities. The Tektronix TDSJIT2 Jitter Analysis software will extend that capability by making jitter measurements on contiguous clock and data cycles from single-shot acquisitions. TDSJIT2 provides many key timing parameter measurements. These 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 and between two separate input signals. Trend plots quickly show how various timing parameters change over time. Comprehensive statistics and histograms of timing parameters enhance the powerful analysis capabilities of TDSJIT2. For the first time, you can make a setup time measurement for a specific data edge to the exact, corresponding clock for all valid transitions in an acquisition.

Tektronix' TDSJIT2 Jitter Analysis software delivers industry-standard jitter and timing analysis capabilities. This software is easily installed in a TDS oscilloscope and does not require any external processing or connections. After installation, the application is accessible from the oscilloscope's front panel.


Tektronix Digital Oscilloscopes Supported -

TDS5000 Series oscilloscopes.

TDS6000 Series oscilloscopes.

TDS7000 Series oscilloscopes.

CSA7000 Series oscilloscopes.

Typical Performance with TDS7404 -

Jitter Noise Floor: 1.5 psRMS

Single-shot Delta Time Accuracy: 3 psRMS*1

*1 TDS7404 RMS accuracy = 0.06/(sample rate) +2.5 ppm*|Measurement|. This gives 3.1 psRMS at 20 GS/s, for a 10 ns measurement.
