    Abstract: The present disclosure relates to a point to point radio link arrangement (100, 600) comprising at least two link nodes (110, 120; 610, 620). A first link node (110, 610) is arranged to obtain first link data (X1) over a first carrier frequency, and a second link node 5 (120, 620) is arranged to obtain second link data (X2) over a second carrier frequency separate from the first carrier frequency. The link arrangement (100, 600) further comprises a classification unit (130, 630) arranged to obtain the link data (X1, X2) from the link nodes (110, 120; 610, 620) and to determine if the link data (X1, X2) are affected by either a frequency dependent disturbance event or by a frequency independent 10 disturbance event. This is accomplished by comparing the first link data (X1) to the second link data (X2) over a time window (T). The classification unit (130, 630) is also arranged to output disturbance event decision data (Y) in dependence of whether the link data (X1, X2) have been determined to be affected by either a frequency dependent disturbance event or a frequency independent disturbance event.

    Abstract: A network access device placed between one or more distribution devices and multiple premises may remotely or wirelessly monitor and/or analyze signal characteristics at the network access device and or of equipment at the multiple premises. The network access device may adjust switchably-filtered signal paths between the distribution device(s) and the multiple premises to remove or mitigate signal interference.

    Abstract: Apparatus and methods for non-invasively monitoring an oscillation signal in an effort to provide a more reliable oscillation signal. An example oscillation circuit generally includes an oscillator configured to generate an oscillation signal, the oscillator comprising an oscillator core circuit for coupling to a resonator and configured to generate the oscillation signal to enable the resonator to resonate and an adjustable current source coupled to the oscillator core circuit and configured to control an amplitude of the oscillation signal; a first automatic gain control (AGC) circuit having an input coupled to an output of the oscillator and having an output coupled to a control input of the adjustable current source; a second AGC circuit configured to replicate the first AGC circuit; and logic having a first input coupled to the output of the first AGC circuit and having a second input coupled to an output of the second AGC circuit.

    Abstract: A method of determining validity for determination on presence of a specific signal of a detector according to an embodiment of the present disclosure includes: (a) receiving a synthesized signal generated from an outside by the detector; (b) acquiring a plurality of frequency domain calculation values related to the synthesized signal; (c) determining the presence of at least one specific signal based on the plurality of frequency domain calculation values; and (d) determining the validity for the determination on the presence of the specific signal based on a frequency domain scatter plot for the plurality of frequency domain calculation values.
