Tektronix, Inc., the world's leading manufacturer of oscilloscopes, announced the industry's first fully automated physical layer transmitter test solution for the MIPI® M-PHY® 3.1 specification and Conformance Test Suite (CTS) 3.1. The solution supports M-PHY High Speed Gears 1, 2 and 3, PWM Mode (G0-G7), and SYS Mode and offers the industry's lowest noise solution for M-PHY measurements when used with Tektronix DPO70000SX or MSO/DPO70000DX oscilloscopes and P7600 series probes.
The mobile industry is moving toward smaller and faster devices that require faster communication between chips over interfaces such as SSIC and need faster access to storage devices over interfaces such as UFS/MIPI UniProSM. This drives the need for higher data rates, higher throughput, modern design implementations and the need for sophisticated test and measurement tools. Automated serial test solutions such as what Tektronix is now offering for MIPI M-PHY 3.1 allow engineers to complete the full set of tests in significantly less time while improving consistency. The automated solution supports advanced analysis, debugging and characterization of devices while allowing designers to test in compliance mode as well as user-defined mode.
"Last year we introduced comprehensive test support for M-PHY 3.1, giving our customers the tools they needed to design cutting edge mobile devices with higher performance and improved efficiency," said Brian Reich, general manager, Performance Oscilloscopes, Tektronix. "Now we are taking our test solution to the next level by giving our customers the advantage of full automation which in turn will help them to bring even higher performing products to market in less time."
The M-PHY TX automated solutions provides support for 100 percent of tests as per M-PHY 3.1 and CTS 3.1 using the TekExpress 4.0 framework, a state-of-the-art tool designed for automation. The backend engine of automation is based on Iron Python which uses socket based programming and .Net remoting. Socket-based scripting interface is a de-facto standard that allows engineers to integrate Tektronix automated solution into their automation environments.
Testing M-PHY transmitters running in high-speed mode requires a scope and probe system with rise time 3X faster than the signal rise time, sensitivity of 200 mVFS, minimal added noise (<1 or 2 mVrms), and high return loss as specified in the M-PHY standard. Tektronix DPO70000SX and MSO/DPO 70000DX oscilloscopes and P7600 Series TriMode probes are the only measurement system available that can meet these requirements while also providing convenient and consistent bus termination for HS measurements with low noise and high sensitivity.
