1. A method, comprising the steps of:
capturing, through an analog data bus coupler coupled to a data bus being connected to a medical apparatus, an emission of electromagnetic energy in a radio frequency (RF) spectrum from the data bus, the emission being captured as an analog emission signal, the analog data bus coupler including at least one of:
a capacitor and a resistor coupled to data lines within the data bus and wherein capturing the analog emission signal comprises acquiring, with the capacitor and the resistor, the analog emission signal as a capacitive signal,
a resistor and a transformer coupled to two data lines within the data bus and wherein capturing the analog emission signal comprises acquiring, with the resistor and the transformer, the analog emission signal as a voltage differential between the two data lines,
one resistor coupled to one line within the data bus, another resistor coupled to another line within the data bus, and an isolating transformer that are all inductively coupled to the data bus, and wherein capturing the analog emission signal comprises acquiring the analog emission signal with both resistors and the isolating transformer,
acquiring, with the analog data bus coupler, the analog emission signal as a common mode difference in voltage or a difference in common mode current flow between a shield and a data line of the data bus, and
two wires, each wire coupled to a data line within the data bus and, wherein capturing the analog emission signal comprises acquiring one of an individual near field transmission of data lines and a difference between near field emissions of the data lines;
processing, with a controller, an emission signature of the analog emission signal; and
identifying, with the controller, based on a processed emission signature, a status of the medical apparatus.
