Abstract: A method is provided for evaluating the reliability of an electrical power measuring device for measuring high-frequency electrical power. To build an evaluation system, the measuring device, together with a reference electrical power measuring device, is arranged between a high-frequency power supply device and an artificial reproduction load, which includes an impedance conversion device and a reference load. Using this system, an uncertainty range of an electrical power measured value measured by the measuring device is calculated, according to a prescribed calculation formula, from the electrical power measured value, and a judgment is made as to whether or not the electrical power measured value measured by the measuring device is within the uncertainty range. If it is within the uncertainty range, the measuring device is evaluated as being reliable, while if it is not within the uncertainty range, the measuring device is evaluated as being unreliable.

Abstract: A measurement system, for use in RF power measurements, allows an arbitrary Bruene-type RF coupler to be calibrated at a number of different power levels and frequencies with an idealized transfer function being created for each calibration power point. Following calibration, when the coupler is used in an operational (measurement) mode, the DC voltage corresponding to the present power measurement is read, and the discrete idealized transfer functions generated during the power and frequency calibration phases are used to determine a best fit idealized transfer function, which is used in conjunction with the exact DC voltage being measured to create a highly accurate power measurement.

Abstract: The invention provides an in-line power monitor for an RF transmission line that is capable of being calibrated in-line during live conditions at the exact power level and frequency where it is used. This device uses forward and reflected directional couplers and a non-directional coupler to sample the RF voltage on the transmission line. The RF voltage of the forward and reflected channels are each split into two paths, one going to a test port and the other leading to additional circuitry which prepares the signals of the forward and reflected channels for output to power displays. Additionally, the monitor allows the user to compensate for any voltage offsets introduced by various circuitry components. Further, the monitor also allows to user to individually calibrate the output of the forward and reflected channels by applying an adjustable gain ratio correction to each channel.

Abstract: An RF detector configured to provide two outputs, one being a function of the true RMS power level of an RF input signal, and the other being a function of the instantaneous/peak power of the RF input signal, normalized to the average power level. The RF detector includes a variable gain detection subsystem including a single detector or detector array that provides a representation of the power level of the RF input signal. The detector or detector array is common to both the RMS power detection channel and the instantaneous/peak power detection channel of the RF detector. A method of RF detection includes providing representations of the RF input signal at different gain levels, selecting one or more of the representations, and averaging the selected signals. The gain levels of the selected representations is adjusted to provide information about the average power level of the RF input signal.
