LXI™-Certified High-Power Automated Tuner
MT981AL/BL/EL/VL Series
Applications & Benefits Overview
The MT981xL series LXI™ controlled automated tuners are optimized for high power in-fixture and on-wafer applications requiring low impedance and low vibration simultaneously. Based on Maury's proven non-contacting probe technology, these high-performance tuners evolve beyond outdated contacting probe technology to deliver high VSWR with superb accuracy and reliability.
An integral component of Maury Device Characterization Solutions, these TCP/IP and USB-interfaced automated tuners are controlled using one of four Maury Software Solutions; Maury's MT930 series IVCAD Advanced Measurement and Modeling Software; Maury's Device Characterization Software suite (ATS version 5 or later); direct ASCII command-and-control, or Maury's DLL environment.
The MT930 IVCAD software suite is the most advanced measurement and modeling software in the industry, with support for multiple load pull techniques including traditional load pull using external instrumentation, VNA-based laod pull, active load pull and hybrid load pull.
ATS software is an integrated device characterization suite providing front-end and back-end device characterization tools for power and noise characterization.
Direct ASCII commands can be sent through raw TCP/IP interface and used with any socket programming language or through any Telnet client program. Commands include direct impedance tuning, reference-plane shifting, VSWR testing and more.
The DLL environment enables direct interface with common programming tools such as Agilent VEE™, NI Labview™, MS Visual Basic & C/C++, and Mathworks MATLAB™.
With a tuning resolution in excess of a million impedance points and accuracy better than -40 dB over the entire Smith chart, Maury automated tuners give you the device characterization answers and critical accuracy you need to make engineering decisions with confidence. Typical applications include load pull using CW, GSM/EDGE, CDMA, WCDMA, WiMax, and WiFi stimulus for mobile and infrastructure terminal design, RADAR design, and Sat-Com design.
The MT981 series tuner is ideal for load pull, harmonic load pull, hybrid active load pull and all automated tuner applications.
Embedded LXI™-Certified Controller
LXI™ is the power of Ethernet and the Web applied to Test & Measurement (T&M) offering you new possibilities in test systems – local, remote, distributed, time-aware. An embedded LXI™-certified controller allows for both TCP/IP and USB control by any personal computer or laptop.
