Signal quality analyser offers high-speed interface measurement functions

Anritsu Corporation has released the Variable ISI MU195020A-040/041 option for upgrading the Emphasis function of the Pulse Pattern Generator for the Signal Quality Analyser-R MP1900A series, along with the USB Link Training Software MX183000A-PL022 supporting the USB3.0/3.1 Receiver Test. The Variable ISI option uses the 10Tap Emphasis function with high and flexible signal controllability to emulate CEI-25G/28G-defined signal path transmission losses which cannot be achieved by utilising an emphasis function with a lower number of taps. Also, the company's MP1900A can automatically calculate the Emphasis settings for compensating these losses based on transmission path S-parameter data. With these new capabilities, test signals emulating the transmission path impairments can be generated easily, allowing the impact of transmission path losses on the evaluated device to be evaluated simply without testing various PC boards, helping to cut development costs and time. USB Link Training is important for measuring USB interfaces; the built-in Link Training function supports transitioning to the device evaluation measurement mode, and when used in combination with the LTSSM Log Analysis, it helps cut times for evaluating USB device receivers and supports cost-effective and all in one measurement of high-speed interfaces such as PCI Express, USB, and Thunderbolt.
