摘要： The present invention provides a filter bank circuit capable of measuring or testing a frequency band, a spectrum analyzer, a signal analyzer, a signal generator using the filter bank circuit, and a method for controlling the filter bank circuit. A filter bank circuit 10 includes, for example, a one-pole two-throw changeover switch 20 and filter groups G1 and G2, each of which has m filters. The passbands of the filters included in each filter group do not overlap with each other, and the adjacent passbands of the filters included in all the filter groups overlap with each other.

摘要： In a method of manufacturing an integrated circuit involving performing an electrostatic discharge (ESD) test, a weak frequency band is detected by sequentially radiating a plurality of first electromagnetic waves on a first test board including the integrated circuit. First peak-to-peak voltage signals are detected by sequentially radiating the plurality of first electromagnetic waves on a second test board including an electromagnetic wave receiving module. A frequency spectrum is detected by radiating a second electromagnetic wave on a housing including a third test board including the electromagnetic wave receiving module. A second peak-to-peak voltage signal is generated based on the weak frequency band, the first peak-to-peak voltage signals and the frequency spectrum. An ESD characteristic associated with an electronic system including the integrated circuit is predicted based on the second peak-to-peak voltage signal.

摘要： A radio frequency (RF) measurement system acting as a spectrum analyzer and a method of operating the same eliminates image signals from a detected input RF spectrum. The method includes determining at least three local oscillator (LO) frequencies; determining LO offsets between the LO frequencies; and mixing the LO frequencies with the input RF spectrum to provide corresponding intermediate frequency (IF) signals having an IF bandwidth, where at least one of the IF signals has the input RF spectrum mixed to a different portion of the IF bandwidth than at least one other of the IF signals, providing overlapping coverage. The method further includes acquiring ADC time records for the IF signals; performing Fourier transforms (FTs) on the ADC time records to provide IF spectrums; and detecting RF responses from the IF spectrums to determine an RF response trace corresponding to the input RF spectrum.

摘要： It is possible to provide a frequency characteristics measuring device which can simplify the configuration for performing a measurement and reduce the undue effort required for the measurement.A spectrum analyzer (10) includes: two sets of measuring units having mixers (110, 210), local oscillators (112, 212), and IF sections (120, 220) for separately measuring frequency characteristics of two input signals; a trigger control section (350) which generates a trigger signal for specifying a measurement start timing in each of the two sets of measuring units; a sweep control section (300) which simultaneously sends an instruction to the two local oscillators (112, 212) when a trigger signal is inputted and performs a sweep control so that the two local oscillators (112, 212) output local oscillation signals of the same frequency at the same timing.

摘要： A system and method to modularize a signal observation process to allow continual adaptation as the independent modules evolve. Receivers, digitizers, storage, and synchronization means form discrete subsystems that can be integrated together yet still be independently upgraded or modified. The integrated system is controlled by software that allows continuous deterministic signal observation for arbitrarily long periods of time. The software enables a schedule-based temporal collection of signals through a method that controls the tuning of the receivers and the downloading of data to storage media. The control software also allows automatic distributed operation of multiple sites in synchronization to within parts per million or better.

摘要： A channel plan with a corresponding test plan are implemented in connection with a plurality of nodes that communicate signals. The channel plan has one or more predefined specifications for each of one or more signal channels on each of the nodes. The channel plan enables a monitoring system to, among other things, conduct automatic periodic test plans, comprising tests, on the nodes, based upon the predefined data specified in the channel plan. Each test plan prescribes measurement of at least one signal parameter, pertaining to one or more nodes as a whole and/or to one or more channels contained within the nodes. The monitoring system includes a spectrum analyzer, a switch enabling the spectrum analyzer to interface with the nodes, and a controller controlling the switch and the spectrum analyzer. The controller is configured to enable creation of and display the channel plan and test plan, based upon user inputs. Notably, the controller can be configured to compare results from tests with alarm limits, specified in the test plan, to control the spectrum analyzer to perform a failure time spectrum scan when one or more test results exceed one or more alarm limits, and to generate a plot of power amplitude versus frequency over the frequency spectrum of the node at issue.

摘要： A frequency divider includes a mixer having a first input connectable to a reference oscillator and a second input connectable from the reference oscillator through a frequency synthesizer to the second input of the mixer. The mixer provides an output signal to a filter, which provides a frequency divider output. The frequency synthesizer provides an output signal having a frequency of (N+1)/N or (N-1)/N times the input F.sub.IN from the reference oscillator. With the frequency synthesizer providing the signal F.sub.IN (N+1)/N, or F.sub.IN (N-1)/N, the output of the mixer provides the signal having the frequency F.sub.IN /N and can utilize a single filter to eliminate undesired mixer outputs. Further, the frequency synthesizer can be configured to utilize an oscillator which operates over the same frequency range as the reference oscillator.
