    Ultrafast analyzer with multiple inputs and multiple outputs. The present addition to the multiple input and multiple output analyzer incorporates a system of one, two or more input/output filters that allow the elements under test to enter and exit the analyzer continuously through one or more tapes. The filter system, which must necessarily cover several bands of working frequencies simultaneously, allows the electromagnetic fields to remain confined inside the analyzer but allows additional slots to those already existing in the analyzer where they can enter and exit the devices under test, allowing an increase of the rapidity of the tests since it avoids the need to open and close the door to introduce and remove said elements under test.

    FIELD OF THE INVENTION F.OEPM23 / 02 / 2017F.EffectiveNº application23 / 02/2017
    The field of invention is the same as for the multiple input and output analyzer, the wireless communication systems. BACKGROUND OF THE INVENTION
    An analyzer of multiple inputs and multiple outputs, is a multimode resonant cavity with high Q factor, with a very inhomogeneous spatial distribution of the electric and magnetic field. There are several elements and methods to homogenize the field such as: the mode agitators, the metal pieces with grooves or the movement of the object under study inside the cavity. Up to now all the mode agitators have been built in metallic materials, some with special shapes as those which can be consulted in WO200054365. On the other hand metal parts with grooves are described in WO2008031964 restricting its application to the aeronautical sector.
    The multimode resonant cavities are used in wireless communications applications to perform measurements in the laboratory that emulate those made for mobile terminals in different propagation environments with an isotropic and Rayleigh distribution. Among the parameters that can be measured are: gain diversity, MIMO capacity, antenna efficiency, absorbed power, correlation between antennas, specific absorption rate, antenna sensitivity, error probability per bit (BER), (being revindicated in US Pat. No. 7,286,961 the measurement of the last two in the reverberation chamber). So far, only measurements of isotropic Rayleigh environments in multimode resonant cavities were possible. There is also the possibility of making measurements with different manikins filled with liquids with losses that simulate different parts of the human body or different tissues, for example, allowing us to investigate the effects produced by the user's head in the mobile terminal.
    Description of the invention
    The ultra-fast multi-input and multi-output analyzer object of the addition F.OEPM23 / 02 / 2017F.EfectivaNº application23 / 02 / 2017only incorporates on the multi-input and multiple-output analyzer the various elements that allow the introduction and extraction of devices under Test continuously and without need to open and close the door, which is used exclusively for cleaning and maintenance tasks.
    The additional elements in the ultrafast analyzer of multiple inputs and multiple output objects of the addition are:
    The first additional element included in the ultrafast analyzer of multiple inputs and multiple outputs are one or more of the slots in the analyzer but practiced on the outer walls and not on the inner metal plate. Through these slots the devices under test can be introduced and extracted with the help of other elements described below.
    The second additional element included in the ultrafast analyzer of multiple inputs and multiple outputs are broadband input and output filters. These filters, of which there may be one or several in an ultrafast analyzer, each consist of a set of small cavities in series, each of them in turn designed to filter a specific band of frequencies through the appropriate insertion of metal poles inside. These cavities, located on either side of the slots in the outer walls of the analyzer, must be designed so that the electromagnetic fields inside the analyzer do not go outside even though the cavities leave their entrance ends and exit a small slot. The cavities will be of different sizes, and they can be placed in a dichroic way, that is, the smaller ones inside the larger ones, in order to reduce the total space needed.
    In third additional element in the ultrafast analyzer of multiple inputs and multiple outputs is the conveyor belt, which in a number of one or several can enter and exit through the same slot or enter through one slot and exit through another, allowing different paths in the inside the analyzer. In this way, the movement that the device under test performs inside the analyzer can also be used as a method of uniformization of the electromagnetic fields that this device perceives, since F.OEPM23 / 02 / 2017F.EfectivaNo application23 / 02/2017 can be used values received in different positions of the device inside the analyzer. This is equivalent but different to the conventional use of a rotary table when it exists and a door is used.
    The first procedure performed by the ultrafast analyzer of multiple inputs and multiple outputs is to apply any of the elements already existing in the analyzer or those added in this document, independently or in combination, to obtain a specific electromagnetic field in the test area . In the case of using the new elements added, necessarily the analyzer door must be closed, that is, the second analyzer procedure to which the present invention is added can not be used. In the drawings:
    Figure 1 shows an ultrafast analyzer with multiple inputs and multiple outputs
    (1) comprising the following elements: a mode agitator (2), located above and below one or more conveyor belts (3), which enter and exit through one or more grooves in the external walls of the analyzer (4) ) and a door (5) for maintenance and cleaning. The part in which the input / output filters (6) would be located, on one side and another of the grooves of the walls through which the devices under test enter and / or leave is also indicated. Embodiment of the invention
    The following example serves to illustrate the addition and should not be considered as limiting the scope of the addition. Example 1: Ultra-fast multi-input and multi-output analyzer for wireless communications
    In the preferred embodiment of the ultrafast analyzer of multiple inputs and multiple outputs (1), the number of input / output filters (6) is 2, associated with 2 slots (4) in the outer walls, by the slots entering and exiting 2 conveyor belts (3). Inside F.OEPM23 / 02 / 2017F.EfectivaNº application23 / 02 / 2017analyzer there are 2 mode agitators, one above and one below the conveyor belts. The signal transmission elements are broadband antennas located at the top of the ultrafast multi-input and multiple analyzer
    5 exits This ultra-fast multi-input and multi-output analyzer features the following novelties:
    The preferred embodiment of the ultra-fast multi-input and multi-output analyzer is designed to be used in the field of wireless communications 10 providing the possibility to emulate all kinds of environments and in different ways without the need to open and close the door to enter and remove the devices under test, which provides a competitive advantage over traditional multimode resonant cavities that can only emulate Rayleigh and isotropic environments or existing systems that require manual introduction and removal of devices
    15 wireless phones under test.
