SignalCorrect™ Software and TCS70902 Calibration Source, Datasheet
Option SC SignalCorrect™ software
Lire en ligne :
SignalCorrect™ allows quick characterization of cables, fixtures and other types of interconnects using the TCS70902 fast step source and the captured response on a DPO/MSO70000 series real-time oscilloscope.
Based on this characterization, SignalCorrect can design a de-embed filter that compensates for the losses that occur in the interconnects, and offers a flat response, enabling signal margin recovery, leading to more accurate measurements.

Features and benefits
Measurement and de-embed: Characterize cables and fixtures and de-embed their effects to gain margin and reduce failures or costly over design.
- Step-by-step characterization process: Easily characterize cables and fixtures and get repeatable results making the solution approachable to novice users.
- De-embed differential and common mode: Enables de-embed of fixtures that may have significant differential coupling and non-ideal common mode behavior.
Two fast step outputs enables dual input measurements and full de-embed of single ended, differential and common mode cases.
- Create and compare: Create multiple filters based on single measurement.
Enables comparison of raw waveform with different filter designs.
- ≤9.4 ps step output: Enables de-embed for greater than 50 GHz (also dependent on oscilloscope bandwidth) useful for next generation designs.
- Small form factor of the step source: Makes it easy to take the source close to the Interconnect Under Test (IUT) for more accurate measurements.
- Stand alone source at lower cost.
- Same performance across all oscilloscope models.
- Reference sine wave output: Enables deskew to < 1 ps to the ends of the cables or fixtures for more accurate measurements.
- Output variation: TCS70902 outputs are based on sampling TDR technology that is well characterized for minimal changes over temperature and time.
- Generic API: Enables integration of the TCS70902 Calibration Source for use in other applications.
- Plot and save: Data such as calibration data, s-parameter data, filters can be plotted making it easy for visualization and saving for later use.
- Real-time scope based solution: Characterize a cable/fixture, design, create and apply a filter all on a real-time scope, eliminating the need for other expensive instruments.
Use the same real-time scope to perform Jitter, Eye Diagram or standard specific measurements on the de-embedded waveform.
The SignalCorrect software application runs on the Tektronix performance oscilloscopes. The application quickly characterizes fixtures, cables, and interconnects for accurate measurement and analysis. Using filter files produced by the application, you can de-embed probes or fixtures and embed a channel model.
The output of the TCS70902 is measured to establish a baseline.
A second measurement is taken after inserting the interconnect under test between the TCS70902 and the oscilloscope.
The two measurements are compared to get the insertion loss of the interconnect under test.
A filter is designed to compensate of for the losses in the interconnect under test and provide a flat response so that signal margin can be recovered to make more accurate measurements.
SignalCorrect provides a step-by-step setup process with connection diagrams to guide you in making the measurements required to characterize the interconnects under test.
SignalCorrect guides you through selecting the calibration data to use or acquiring new calibration data.
During the calibration process a reference measurement is taken to establish a baseline.
During the calibration step:
- Factory calibration data stored on the source can be used if the Interconnect under test can be directly connected to the source.
- New calibration can be used in all other cases.
- Saved calibration data from previous calibration runs can be used to reduce time for characterization.
SignalCorrect extracts the insertion loss of the interconnect under test. A plot of the insertion loss is also shown.
SignalCorrect creates a filter that you can apply to your oscilloscope inputs to de-embed your device or interconnect under test.
