Software helps serial analysers
work end to end
High speed serial data analysis software package covers signal chain from transmitter to receiver and including the connecting channel
Tektronix has a new end-to-end high speed serial data analysis software package with test capabilities extending from a transmitter to a receiver and including the connecting channel. The new 80SJNB Advanced software runs on the Tektronix DSA8200 digital serial analyser. 80SJNB Advanced combined with the DSA8200 platform's TDR/TDT and S-Parameter support through iConnect software provides engineers with the first complete serial datalink analysis (SDLA) package to ensure a readable signal reaches the receiver.

Using FPGAView, design engineers can quickly and easily measure signals inside their Altera and Xilinx FPGA design and select which group of internal signals to probe
The latest high-speed serial technologies are at the core of the computer, consumer electronics, and communications industry designs and require test equipment capable of higher performance and more extensive analysis.
The new 80SJNB Advanced software includes feed-forward and decision feedback equalisation (FFE and DFE) for a virtual view of the signal as it appears at the comparator inside the receiver.
Emulation of the interconnect channel enables testing the transmitter performance against multiple interconnects.
Support for fixture de-embedding facilitates virtual probing at inaccessible points.
The complete SDLA offering provides the fundamental measurements needed to validate compliance of high-speed serial standards such as 10Gbit/s Ethernet, PCI-Express and SATA, enabling the development of higher performance products for the new digital world.

Framework to automate compliance testing
The combination of Tektronix instruments and the open nature of NI TestStand software gives customers a platform to rapidly characterise new products and bring them to market faster
'As serial data speeds increase, loss and distortion caused by the channel must be equalised in the receiver for the signal to be recognisable', says Ian Valentine, General Manager, Electrical Optical Product Line, Tektronix.
'The DSA8200 measurement system already provides channel characterisation with TDR/TDT and S-Parameter support'.
'The new 80SJNB Advanced software with complete equalisation and channel emulation provides the most advanced serial data link analysis test tools in the industry'.
'Using a SDLA measurement system from Tektronix, an entire design from the transmitter to the receiver comparator can be characterised and tested for compliance'.
'Due to the higher speed of the latest serial interface standards under development, test fixturing and small changes in the channel can cause significant changes to the signal characteristics', says Eric Kvamme, Principal Engineer, LSI Logic.
'With their ability to de-embed fixtures, emulate channels, and model equalisation right on the high speed scope, the new Tektronix SDLA tools including the DSA8200 with 80SJNB Advanced software help LSI to more quickly characterise our serial products'.
'This will enable us to evaluate their performance under additional scenarios to provide a more robust solution to our customers'.
Equalisation is a broad term for several techniques of manipulating the signal shape in order to overcome frequency dependent loss of the channel.
This loss changes the shape of the NRZ data signal at the receiver from the desired square-wave to severely distorted, closed eye waveform.
80SJNB Advanced provides the important equalisation methods of FFE and DFE on the receiver side, and supports generation and measurement of pre-emphasis and de-emphasis on the transmitter side.
Another capability of the software is channel emulation, providing customers a pushbutton way to see the waveform impairments due to channel (interconnect) transmission loss.
Through channel emulation engineers are able to acquire the signal at the transmitter output, and distort it by an (emulated) channel - be it a backplane, connector, anything that can be described with TDR/TDT or with S-Parameters - and verify the performance at the channel end, without waiting for the physical hardware's availability.
Final analysis is performed using 80SJNB Advanced jitter and noise decomposition and BER eye diagrams.
With 80SJNB Advanced, design engineers gain the ability to compare different transmitter-to-channel-to-equaliser combinations, resulting in improved design and verification.
The waveform and the eye diagram at any point are not only viewable, but also available for a complete jitter, noise and BER analysis.
Acquisition and advanced analysis of complex signals is increasingly needed on transmitters with spread spectrum clocks (SSC).
80SJNB software and the DSA8200 now provide engineers a sampling oscilloscope with an unmatched ability to perform SSC acquisitions and SSC jitter analysis.
SSC is widely used in desktop and laptop PCs and is incorporated into standards including SATA and PCI-Express.
80SJNB Advanced software is available with a new DSA8200 or as an upgrade if a customer has already purchased 80SJNB or 80SJNB Essentials.
The MSRP for 80SJNB Advanced is Eur 13,700 or GBP 9160 when ordered with a DSA8200.
Existing customers of 80SJNB software can download 80SJNB Essentials from the Tektronix website free of charge, or can upgrade to 80SJNB Advanced for Eur 4240 or GBP 2840.
Older Tektronix sampling mainframes are supported as well; however, an upgrade to the computing platform is required in some cases. Request a free brochure from Tektronix....
