摘要： Power levels for a code-division multiple access (CDMA) signal with layered orthogonal codes are displayed. When displaying power levels for multiple code layers, a power level for each active code channel is displayed using a bar. A width of the bar indicates in which code layer each active code channel is active. A color of the bar also can be used to indicate in which code layer each active code channel is active. For example, a power level for each active code channel is displayed using a hollow bar and a power level for each inactive code channel is displayed using a line. Alternatively, a power level for each inactive code channel is displayed using a hollow bar and power level for each active code channel is displayed using a solid bar. When displaying a power level for a single code layer, a power level for each active code channel in the single code layer is displayed using a hollow bar, and a power level for each code channel which is inactive in the single code layer is displayed using a line. Alternatively, when displaying a power level for a single code layer, a power level for each active code channel in the single code layer is displayed using a solid bar, and a power level for each code channel which is inactive in the single code layer is displayed using a hollow bar.

摘要： A number of RF receivers are connected in a network. The network is used to transmit communications, data, or both to and from the RF receivers and to synchronize the RF receivers to a common time. Digitized RF data is time-stamped and stored in memory. A trigger circuit in one or more RF receivers determines whether a trigger criterion or criteria has been met. When a trigger criterion or criteria has been met, some or all of the RF receivers in the network transmit select digitized RF data to a central processing device. The central processing device processes the select digitized data to detect if a signal is present.

摘要： A correction processor connected to an oscillator uses precision timing signals propagated over a digital network to generate an error signal. IEEE-1588 time synchronization protocols produce precision time signals which are converted to precision interval signals. The correction processor uses the precision interval signals to count pulses of the oscillator. A correction circuit compares the counter output with a predetermined value and generates an error signal may be used to correct the oscillator or may be propagated to consumers of the oscillator. An arbitrary reference oscillator may be used to generate the precision timing signals propagated on the network, to slave other oscillators to it. The precision of the reference oscillator may be deliberately overstated to insure it is used as a master.

摘要： A system and method are provided which add, via an add-on module, synchronization functionality to an instrument that does not otherwise support such synchronization functionality. Various synchronization techniques may be supported by the synchronization module. For instance, in certain embodiments the synchronization module supports message-based synchronization techniques and/or time-based synchronization techniques. Accordingly, in certain embodiments, the add-on module supports synchronization with another device (e.g., another instrument or another add-on module coupled to an instrument) via synchronized local clocks (e.g., IEEE 1588) and messaging over a communication network. In certain embodiments, the add-on module additionally or alternatively supports the use of “time bombs” to trigger scheduled actions on the instrument with which the synchronization module is interfaced.

摘要： Location of an emitter using leaky cables. A two-channel receiver determines the location of an emitter by measuring the phase and/or amplitude difference between emitter signals received by leaky cables. In one embodiment, two leaky cables having different propagation velocities are used. In a second embodiment also suitable for use with fiber optic cables, two cables having the same propagation velocity are used, but have different lengths, the extra length being taken up by serpentine patterns or loops. A single cable in a loop may also be used. The leak points on the cables may be passive, or may be controlled RF switches.

摘要： In a response calibration method, a stimulus signal having a non-zero bandwidth is coupled to a receiver through a signal path that introduces distortion to the stimulus signal. The receiver acquires a first digital representation of the stimulus signal at an output of the signal path with the receiver adjusted to a first spectral position, and acquires a second digital representation of the stimulus signal at the output of the signal path with the receiver adjusted to a second spectral position that is shifted from the first spectral position by a predetermined frequency offset. The frequency response of the receiver when the receiver adjusted to the first spectral position is equated to the frequency response of the receiver when the receiver is adjusted to the second spectral position. A first combined frequency response of the receiver and the signal path is extracted at three or more designated frequencies within the bandwidth of the stimulus signal, and a second combined frequency response of the receiver and signal path is extracted at a set of frequencies offset from the three or more designated frequencies by the predetermined frequency offset. The frequency response of the receiver is determined from the first combined frequency response and the second combined frequency response. The frequency response of the signal path is optionally determined according to the response calibration method under condition that the stimulus signal is known, characterized, designated or otherwise established.

摘要： The response of a receiver is calibrated using frequency-shifted stimulus signals. A source provides a stimulus signal that has a non-zero bandwidth and an adjustable spectral position. A signal path coupled between the source and the receiver introduces distortion to the stimulus signal. The receiver acquires a first digital representation of the stimulus signal at an output of the signal path with the stimulus signal adjusted to a first spectral position and acquires a second digital representation of the stimulus signal at the output of the signal path with the stimulus signal adjusted to a second spectral position that is shifted from the first spectral position by a predetermined frequency offset. A processor, designates the distortion introduced to the stimulus signal by the signal path to be equivalent at the first spectral position and the second spectral position. The processor extracts a first combined frequency response of the receiver and the signal path at three or more frequencies within the bandwidth of the stimulus signal, and extracts a second combined frequency response of the receiver and signal path at the three or more frequencies and then determines the frequency response of the receiver from the first combined frequency response and the second combined frequency response. The response of the signal path is optionally determined according to the response calibration scheme under condition that the stimulus signal is known, characterized, designated or otherwise established.

摘要： A narrowband spectrum analyzer separates and analyzes a chosen segment of a periodic signal. The signal to be analyzed is digitized by an A/D converter. A gate generator is configured to trigger on a particular portion of the signal waveform and to identify the beginning and end of the chosen segment. Over the interval of the segment, the gate generator produces a digitized gate sequence. The envelope of this sequence may be rectangular or, preferably, may be that of a particular window function. The digitized signal is multiplied by the gate sequence and the multiplier output is then furnished as a train of gated segments to a signal processor for narrowband (high resolution) spectrum analysis. The length of the train is chosen to enable the signal processor to provide the desired resolution. Provision is made for removal of any DC component in the chosen segment before multiplication to reduce the possibility of aliased spectral terms in the processor output. Presuming that the signal within the segment interval is a portion of an underlying, continuous signal, provision is made for inferring the amplitudes of the components of the continuous signal.
