Agilent Technologies Inc. has introduced the Agilent N1055A 35/50 GHz (8 ps) time-domain reflectometry and transmission module for the Agilent 86100D DCA-X platform. The 86100D DCA-X oscilloscope mainframe can be configured with one to four N1055A TDR/TDT plug-in modules to provide a 2- to 16-channel TDR/TDT measurement system that is both economical and accurate.
The 2/4 port TDR/TDT remote heads can be configured with a sampler bandwidth of 35 or 50 GHz, providing single-ended and differential measurement capability, including True-Mode stimulus functionality. With TDR step edge speeds as fast as 8 ps and receiver bandwidths of 50 GHz, the DCA-TDR solution resolves the magnitude and location of impedance discontinuities with unmatched performance.
With Agilent 86100D Option 202 enhanced impedance and S-parameter analysis software, scattering parameters (S-parameters) are generated in real time within the oscilloscope and simultaneously displayed with time domain results. The N1055A’s fast rise time enables calibrated S-parameter measurements to 50 GHz and above. The high-channel-count capability of the DCA-TDR solution also helps to minimize cable reconnections and facilitate more efficient near-end crosstalk and far-end crosstalk measurements in both R&D and high-volume test applications.
The DCA-TDR solution achieves a significant breakthrough for accuracy and ease-of-use with its support for electronic calibration (ECal) modules, leveraging an advanced calibration technique originally developed for vector network analyzers and recognized as the “gold standard” in S-parameter measurements. A special Agilent N4694A DC 67 GHz ECal module was developed for the DCA-TDR to let users calibrate and de-skew channels and TDR modules quickly.
