摘要： A signal analyzer for facilitating observation of a relative value, i.e., the quantity of variation in power between slots, at the time of analyzing the power of a signal which is to be measured and subjected to power control in units of slot. An analyzing section (27) detects the power value of every slot of a signal which is to be measured and received at a receiving section (6), and calculates the relative value of the power value between each slot and a slot separated therefrom by a predetermined number. A display control section (29) displays the relative values thus calculated as a graph at a display section (10) by arranging them continuously in time series.

摘要： In this demodulation method, a receive signal is demodulated estimating the fading distortion of data by detecting the fading distortion of unique word as pilot signal inserted into multiple sections of the receive signal. The method has the steps of: comparing a unique word in the multiple sections of receive signal and a known unique word and thereby detecting the fading distortion of unique word in the multiple sections; calculating a spline interpolation curve based on the fading distortion of unique word in the multiple sections; estimating the fading distortion of data in the receive signal from the spline interpolation curve; and demodulating the data in the receive signal based on the fading distortion of the data.

摘要： A tester (10) for multiple types of radios (34) has a first group of generic test elements (14) common to all types of radios to be tested and second groups of test elements (12) specific to each one of the multiple types of radios (34). Each of the second groups of test elements (12) is mounted within a pluggable module (12) for insertion into the tester (10) where it couples to a common bus (16) accessed by all of the other test elements (12, 14) and by the controlling computer (18). Each pluggable module (12) contains a specific identifier which, when accessed (284) by the controlling computer (18) initiates a stored program (288) which causes the computer (18), via the bus (16), to couple the various test elements (12, 14) into a configuration required to test the radio type (34) associated with that identifier. The tester (10) is very compact and conveniently uses a lap top computer (18) as the controlling element.

摘要： The invention relates to a device for looping a radio-frequency test signal transmitted by the transmitter section in a transceiver to a receiver section for testing the transceiver. In the device of the invention, a transmitting-frequency test signal is first demodulated (23) to a base frequency and then to a receiving-frequency test signal. A control means (38) applies frequency setting signals to two frequency synthesizers (44, 45) before the beginning of each test interval and monitors the locking of the output frequencies of the synthesizers, thus preventing the output signal of the modulator (28) from being applied to the receiver section during the test interval if the output frequencies of the oscillator means (44, 45) have not locked to local oscillator frequencies determined by the frequency setting signals before the beginning of the test interval.

摘要： A test and measurement instrument and associated methods for acquiring and stitching wide overlapped non-uniform frequency bands so that a user specified band can be efficiently displayed and analyzed is disclosed. The test and measurement instrument includes a user interface (298) to receive the user specified frequency span. Acquisition circuitry (203) acquires one or more predefined frequency bands (270)having non-uniform overlapping frequency ranges. A frequency band processing section (290) can decimate (252) the acquired frequency bands, mask (294) the acquired frequency bands, and stitch (296) the masked frequency bands together. A display section (202) displays the user specified frequency span using the stitched frequency bands. Due to the overlap configuration of the wide non-uniform bands, any user specified span between 50 kHz and 6 GHz, or thereabout, can be covered by two bands.

摘要： There is a need to reduce secondary intermodulation distortion that may occur in a reception circuit of a high-frequency signal processor and a wireless communication system having the same. In test mode, for example, a test signal generating circuit TSGEN generates a test signal RFtst at f_tx ±0.5 MHz. The test signal RFtst is input to a mixer circuit MIXrx_I (MIXrx_Q). A correction circuit block CALBK detects an IM2 component resulting from the MIXrx_I (MIXrx_Q). The CALBK varies a differential balance for the MIXrx_I (MIXrx_Q) and concurrently monitors a phase for the IM2 component resulting from MIXrx_I (MIXrx_Q). The CALBK searches for the differential balance corresponding to a transition point that allows the phase to transition by approximately 180°. The MIXrx_I (MIXrx_Q) operates in normal mode using the differential balance as a search result.
