Abstract: A data acquisition system senses current and voltage from a common electrical circuit supplying a power to load branch circuits containing loads that undergo changes in load condition, such as starting and stopping. Transmitters connected to the load branch circuits identify the loads that undergo load condition changes. A data processor receives information from both the sensors and the transmitters to link the sensed current and voltage information from the common electrical circuit to the particular loads that undergo changes in load condition.

Abstract: A temperature compensated power detector generally comprises a detector circuit portion, which includes a detector diode, and a temperature compensation circuit portion, which includes a temperature compensation diode, that is operably connected to the detector circuit portion. The detector diode and the temperature compensation diode are connected in DC series with each other and develop substantially identical voltage drops. The detector circuit portion operates to detect a voltage from a power input. However, the detected voltage is subject to alteration due to temperature variations. The temperature compensation circuit portion develops a voltage that is also subject to alteration due to temperature variations. The temperature altered voltage of the temperature compensation circuit portion is used to cancel out the temperature altered voltage of the detector circuit portion allowing the power detector to produce a true voltage output.

Abstract: Power measuring receiver (PMR) methods and apparatus for measuring power of signals are provided in which a high frequency measuring circuit (HFMC), a conversion measuring circuit (CMC), and an intermediate frequency measuring circuit (IFMC) work in conjunction with each other to measure a wide power range of signals. The HFMC may measure relatively high power signals at high frequency. The CMC may convert the high frequency signal into an intermediate frequency signal so that both the CMC and the IFMC can accurately measure low power signals. The CMC may also set the minimum noise bandwidth associated with gain stages in the IFMC. The intermediate frequency may provide the IFMC with the ability to perform low power measurements at a reduced DC power consumption.

Abstract: An RF detector (15) is formed to compress the output voltage at two different rates depending on the value of the output voltage. Using two different rates of compression reduces saturation of the output voltage and reduces distortion. The RF detector (15) also provides temperature compensation in the output voltage to reduce output voltage variations due to temperature changes.

Abstract: A power sensing RF termination comprising a calibration means allows the user to correct for part-to-part variation, miss match loss and output offset. The power sensing RF termination comprises a first and second temperature sensitive resistors connected at a first common junction, a switching means for connecting either an RF input or a DC power reference to the first common junction, a first switch for connecting either a DC voltage source or a first current detecting resistor to the first temperature sensitive resistor, and a second current detecting resistor connected to the second temperature sensitive resistor. A first output terminal is connected to the junction between the first switch and the first temperature sensitive resistor. A second output terminal is connected to the first common junction. A third output terminal is connected to the junction between the second temperature sensitive resistor and the second current detecting resistor. The first and second temperature sensitive resistors have substantially the same temperature coefficient of resistance; but the first temperature sensitive resistor has a positive temperature coefficient of resistance while the second temperature sensitive resistor has a negative temperature coefficient of resistance. Using the measurements of the voltages at the first, second and third output terminals, a calibration table is formed correlating the power absorbed in the first and second temperature sensitive resistors to the ratio between the voltage drop across either the first or second temperature sensitive resistor and the voltage drop across both the first and second temperature resistive resistors.

Abstract: The present invention relates to a switched attenuator diode microwave power sensor and more particularly to a true average, wide dynamic range microwave power sensor utilizing a switched step attenuator on the sensor input. The present invention provides a sensor that uses a switched attenuator to always keep the signal to the sensor diodes in their “square law” region of operation has significant advantages over the prior art. Staying in the valid “square law” operating region will enable accurate measurements to be made on arbitrarily modulated signals of high peak to average ratio

Abstract: The invention provides a true average, wide dynamic range microwave power sensor using a diode-stack-attenuator diode stack technology. The invention provides a diode stack microwave power sensor which includes an RF signals receiver having wide dynamic power ranges; a low power sensor path connected between the receiver and ground for sensing relatively low power RF input signals. The low power sensor path includes one or more stacked RF diodes in which a number of diode pairs may be coupled to ground through respective capacitors. An impedance network including attenuating resistors R1 and R2 are connected in series between the receiver and ground. A high power sensor path is connected in parallel between the attenuating resistors R1 and R2 and ground for sensing attenuated relatively high power RF input signals. The high sensor path includes a second stacked RF diode in which a second number of stacked diode pairs are coupled to ground through a respective capacitor, and in which the sensor diode operates in the square law region and senses the power levels over the wide dynamic ranges of the received RF signals.
