This disclosure describes a system and method for generating images by performing TEM surveys using pre-existing infrastructure such as transmission lines, or power lines, and naturally occurring transients such as lightning strikes or load switching. A relatively inexpensive sensor array can be installed on overhead power lines (e.g., electrical transmission or sub-transmission lines) which can detect transients in the overhead power lines. Transients in the overhead power lines can cause the power lines to emit pulses of electromagnetic (EM) radiation, which propagate into the earth's subsurface. This sudden change in electromagnetic field in the subsurface can induce eddy currents, which in turn emit return EM radiation that can propagate back to the overhead power line and induce secondary voltage and current transients. The magnitude of these secondary transients, and their time delay from the original transient are influenced by the properties of the subsurface in which the eddy currents formed.

A method for use in performing a diagnostic test on a mobile electronic device, comprises: (i) transmitting, from a server to the mobile electronic device, data defining a portion of an algorithm, the algorithm defining the diagnostic test; (ii) executing, on the mobile electronic device, the portion of the algorithm; and (iii) repeating steps (i) and (ii) for each portion of the algorithm until the diagnostic test is complete. Such a method may avoid any requirement to install a computer program defining an algorithm for a diagnostic test on the mobile electronic device. The present disclosure also relates to a system, a method and a computer program for use in performing a diagnostic test on a mobile electronic device and, in particular, though not exclusively for use in performing a diagnostic test on a mobile phone, a smartphone, a tablet or a laptop.

A modular test instrument for performing tests and measurements in a network is disclosed. The modular test instrument may include a modular processing unit comprising a processor and memory, the modular processing unit connectable to at least one modular test unit or modular test subunit. The modular test instrument may also include a modular display unit connectable to the modular processing unit or the modular test unit. Display modularity may enable quick and cost-efficient display replacement when damage, malfunction, or failure is incurred. Furthermore, the modular test instrument may include an additional modular test subunit connectable to at least one of the modular processing unit or the modular test unit. When the modular processing unit is fitted with the modular display unit, the modular least, or modular test subunit, for example, the modular test instrument may form an integrated test instrument for performing any number of tests and measurements associated with installation, troubleshooting, or maintenance of a long-term evolution (LTE) or 5G network.
