Abstract:
1. A signal acquisition probe comprising: a housing having a probing tip extending from one end of the housing, the probing tip configured to acquire time domain data samples to characterize a frequency response of the signal acquisition probe, and an electrically conductive cable extending from the other end of the housing with electrical circuitry disposed within the housing and coupled to the probing tip and the electrically conductive cable; a controller configured to compress the time domain data samples into a compressed time domain data sample record, as a function of a value representing the rate of change of magnitude values of the time domain data samples, when the rate of change value exceeds a threshold value; a memory associated with the signal acquisition probe configured to store the compressed time domain data sample record derived from acquired time domain data samples representative of a step response of the signal acquisition probe, wherein the compressed time domain data sample records include at least a first step response and a second step response selected from the group including a forward through step response, reverse through step response, input reflection voltage step response and output reflection voltage step response of the signal acquisition probe, wherein the first step response and the second step response are different and the first step response and the second step response characterize the frequency response of the signal acquisition probe.
