Automated Mobile Test System Software (AMTSv2)
The Maury Automated Mobile Test System Software (AMTS v2.00) is a standalone application designed specifically to automate the testing of mobile phones in transmit and receive modes, for output power and sensitivity respectively, as a function of VSWR magnitude and phase.

The Maury Automated Mobile Test System Software (AMTS v2.00) is a standalone application designed specifically to automate the testing of mobile phones in transmit and receive modes, for output power and sensitivity respectively, as a function of VSWR magnitude and phase.
AMTS is designed to run under Microsoft® Windows™ 2000 and Windows™ XP.
Mobile Phone TX/RX Load Pull
Load pull consists of varying (pulling) the load impedance seen by a device-under-test (in this case the cell phone) while measuring its performance. This method is especially important for measuring large-signal nonlinear devices where the operating point may change with power level or tuning. Maury AMTS software is designed to automate these load pull measurements.
Mobile phones must guarantee proper functioning in non-ideal real-world environments, such as a lost or damaged antenna, usage in a tunnel or locker, being held close to the body or in a pocket surrounded by coins, etc. Each of these scenarios can be regarded as non-ideal from an RF standpoint, meaning non-50 ohm. Maury's AMTS software makes it possible to accurately measure the output power and receiver sensitivity of a mobile phone under conditions that simulate a variety of non-50 ohm environments. AMTS automates the testing of mobile phones in TX and RX modes over a multitude of channels/frequencies, battery voltages and power levels. Users are able to vary the VSWR magnitude and phase seen by the antenna port of the phone and test its real-time TX/RX performance.
To perform TX/RX tests on mobile phones, the following equipment is needed in addition to the AMTS software: a phone to act as device under test (DUT), a tuner to vary the VSWR seen by the phone, a DC power supply to vary the voltage applied to the phone, and a Wireless Communication Test Set (i.e., Agilent 8960 or Rohde Schwarz CMU200) to act in signaling or non-signaling mode and test power and biterror rate (BER).
