Abstract: A method is provided for performing receiver and transmitter tests of a phased array antenna using a test system including probe antennas for transmitting and receiving RF signals, respectively. For the receiver tests, the method includes receiving the RF signals at receiver channels over propagation paths corresponding to the probe antennas, where each of the receiver channels is set at a selected complex gain setting of multiple available complex gain settings; measuring a combined receive signal output from a single combined output of the phased array antenna; isolating complex gain and complex path loss products from the measured combined receive signal corresponding to the selected complex gain setting and the propagation paths at each of the receiver channels; and determining a relative value between the complex gain of one receiver channel and previous complex gain of the one receiver channel using the isolated complex gain and complex path loss products.

Abstract: The output power of a signal generated by a mobile communications device is measured over a short period of time (e.g. one signal burst), and the data modulation carried by the signal is also determined. The measured power value is adjusted to compensate for variations due to the content of the data modulation. This enables the long-term average power output by the device to be determined more quickly than by averaging the power measured over many successive signal bursts.

Abstract: Heat exchange apparatus and process, particularly heat exchange primary reforming with the primary reformed gas being subjected to partial combustion (and optionally secondary reforming) and the resultant partially combusted gas being used as the heat exchange medium to supply heat required for the primary reforming. The apparatus includes process fluid inlet and outlet zones separated from the heat exchange zone by boundary means such as tube sheets or header pipes. A plurality of heat exchange tubes for a process fluid extending through a heat exchange zone from one of the boundary means and slideably engage at the other boundary means with seal tubes fastened to said other boundary means.
