Atlas Si for Touchstone Delta-L4.0 insertion loss processing

Atlas for Touchstone Delta-L PCB insertion loss processing supports Delta-L 4.0 Eigenvalues * PCB insertion loss test methods to 43.5GHz

The Atlas Touchstone insertion loss processing system

The Atlas for Touchstone insertion loss processing system is designed to assist PCB technologists and Si Engineers process raw .s4p Touchstone files containing short / long line 4 port s-parameter data. In addition to processing the Atlas curates the processed data and readily passes the processed insertion loss measurements into the Polar Si9000e PCB transmission line field solver for further analysis.

If you need to process and analyse raw insertion loss data from a PCB vendor Atlas Si for Touchstone can simplify this process

Designed to import short line long line insertion loss data in .s4p file format and de-embed the results into a convenient form for pasting into a compatible field solver for detailed analysis, Atlas Si for Touchstone groups results for given designs as they would appear on a test coupon. In this way you can save result data by coupon or by supplier - and also save the processed results in an Atlas Snapshot(TM) file for fast analysis in the future..

Atlas Si for Touchstone marshals all your supplier test data into convenient coupon lists (Test lists) where each processed PCB insertion loss test coupon data is saved together in an Atlas file. Industry standard Touchstone format permits processing of data from any brand of Vector network analyser.

Multi-GHz PCB fabrication

For PCB Technologists and Si engineers who need to manage test qualification results from a diverse array of PCB suppliers Atlas for Touchstone allows a common tool for processing short line long line data. PCB fabricators experience in the multi GHz arena varies widely and Atlas Si for Touchstone allows Si engineers a vehicle to import raw test data for validation from new and existing suppliers adding confidence to the validation process as a result.

Delta-L test method

Atlas for Touchstone is compliant with IPC TM650 2.5.5.12 (Test Methods to Determine the Amount of Signal Loss on Printed Boards) and supports the Delta-L 4.0 test method for extraction of differential insertion loss and effective Er from a suitably designed coupon.

The Delta-L technique uses long-line short-line measurement combined with innovative via de-embedding techniques.

Seamless communication with Si9000e insertion loss field solver.

Copy and paste your processed touchstone files so you can compare measured with modeled data. The image below shows Atlas processed touchstone loss data overlaid with predicted attenuation and the modeled split between copper / copper roughness / and dielectric losses. The measured attenuation shown in brown.

Atlas uses powerful mathematical processing techniques to allow measurement of differential frequency-dependent losses from a pair of .s4pTouchstone files sourced via VNA measurements from an insertion loss coupon. The system is easy to set up, easy to use and delivers fast results which are easy to further analyse through a direct copy and paste into the Polar Si9000e field solver..
