A system for collecting measurement data from a device under test, DUT, and from equipment of a same equipment type as the DUT, the system comprising: a mobile computing device comprising: at least one processor; a measurement collection engine configured to obtain measurements from multiple measurement devices, wherein at least one measurement device measures a parameter of the DUT, and wherein at least one other measurement device measures a parameter of other equipment of the same equipment type as the DUT; a measurement data store configured to store a plurality of measurements obtained by the measurement collection engine; and a nontransitory computer-readable medium having computer-executable instructions stored thereon that, in response to execution by the at least one processor, cause the mobile computing device to: receive a first time series of measurements of the DUT and a second time series of measurements of the other equipment of the same equipment type as the DUT; store the first and second time series of measurements in the measurement data store; and display a graph of the first and second time series of measurements to a user, wherein the graph compares measurements taken of the DUT and measurements taken of the other equipment of the same equipment type as the DUT at different locations and different times; wherein the instructions cause the mobile computing device to retrieve measurement data and display in the graph the measurement data side-by-side or picture-in-picture showing the measurements over time for the DUT and for the other equipment of the same equipment type as the DUT. a mobile computing device comprising: at least one processor; a measurement collection engine configured to obtain measurements from multiple measurement devices, wherein at least one measurement device measures a parameter of the DUT, and wherein at least one other measurement device measures a parameter of other equipment of the same equipment type as the DUT; a measurement data store configured to store a plurality of measurements obtained by the measurement collection engine; and a nontransitory computer-readable medium having computer-executable instructions stored thereon that, in response to execution by the at least one processor, cause the mobile computing device to: receive a first time series of measurements of the DUT and a second time series of measurements of the other equipment of the same equipment type as the DUT; store the first and second time series of measurements in the measurement data store; and display a graph of the first and second time series of measurements to a user, wherein the graph compares measurements taken of the DUT and measurements taken of the other equipment of the same equipment type as the DUT at different locations and different times; at least one processor; a measurement collection engine configured to obtain measurements from multiple measurement devices, wherein at least one measurement device measures a parameter of the DUT, and wherein at least one other measurement device measures a parameter of other equipment of the same equipment type as the DUT; a measurement data store configured to store a plurality of measurements obtained by the measurement collection engine; and a nontransitory computer-readable medium having computer-executable instructions stored thereon that, in response to execution by the at least one processor, cause the mobile computing device to: receive a first time series of measurements of the DUT and a second time series of measurements of the other equipment of the same equipment type as the DUT; store the first and second time series of measurements in the measurement data store; and display a graph of the first and second time series of measurements to a user, wherein the graph compares measurements taken of the DUT and measurements taken of the other equipment of the same equipment type as the DUT at different locations and different times; receive a first time series of measurements of the DUT and a second time series of measurements of the other equipment of the same equipment type as the DUT; store the first and second time series of measurements in the measurement data store; and display a graph of the first and second time series of measurements to a user, wherein the graph compares measurements taken of the DUT and measurements taken of the other equipment of the same equipment type as the DUT at different locations and different times; wherein the instructions cause the mobile computing device to retrieve measurement data and display in the graph the measurement data side-by-side or picture-in-picture showing the measurements over time for the DUT and for the other equipment of the same equipment type as the DUT.
