Systems and methods for storing data associated with an excursion event detected by a power monitor device

A method, comprising:

• generating, by measurement circuitry connected to a first channel monitoring interface, a series of first channel measurement samples associated with a first power rail;
• storing the first channel measurement samples in a first data buffer;
• detecting, by control circuitry, a defined excursion event at an event detection time based at least on an event triggering sample of the first channel measurement samples;
• in response to the detection of the defined excursion event, storing a first sample set including the event triggering sample and at least one first channel measurement sample stored in the first data buffer prior to the event triggering sample;
• receiving a request for the stored first sample set;
• and
• in response to the received request, providing access to the stored first sample set.

A system, comprising:

• multiple data buffers associated with multiple channels of a power monitor device, each of the multiple data buffers configured to receive a respective series of digital measurement samples associated with a respective channel of the multiple channels;
• and
• control circuitry to:
• detect a defined excursion event, at an event detection time, based at least on an event triggering sample in the series of digital measurement samples associated with a respective channel of the multiple channels;
• in response to detecting the defined excursion event, store a respective sample set associated with each channel of the multiple channels, wherein the respective sample set associated with each respective channel includes at least one of the measurement samples stored in the respective data buffer associated with the respective channel prior to the event detection time;
• receive a request for at least one sample set associated with at least one channel of the multiple channels;
• and
• in response to the received request, provide access to the requested at least one sample set.
