Testing Device and Testing Method with a fading simulator

A testing method for testing a device under test, wherein the testing method comprises the steps of:

• generating a first number of signals according to a number of transmitting means Ntx for a simulated transmission to a device under test,
• simulating the transmission channels between said transmitting means and a number of receiving means Nrx of the device under test with the aid of an extended channel correlation matrix R{tilde over (H)}DL comprising a channel correlation matrix RHDL, the extended channel correlation matrix R{tilde over (H)}DL based on receive antenna characteristics of the device under test and/or transmit antenna characteristics, and
• outputting a second number of faded signals to the device under test, the second number of faded signals corresponding to the number of receiving means Nrx of the device under test.

One or more non-transitory computer-readable media storing computer-executable instructions that, when executed, cause one or more processors to perform acts comprising:

• generating a first number of signals according to a number of transmitting means Ntx for a simulated transmission to a device under test,
• simulating the transmission channels between said transmitting means and a number of receiving means Nrx of the device under test with the aid of an extended channel correlation matrix R{tilde over (H)}DL comprising a channel correlation matrix RHDL, the extended channel correlation matrix R{tilde over (H)}DL based on receive antenna characteristics of the device under test and/or transmit antenna characteristics, and
• outputting a second number of faded signals to the device under test, the second number of faded signals corresponding to the number of receiving means Nrx of the device under test.
