Embodiment Construction

[0035] For ease of description and understanding, the terms involved in this case are first described as follows:

[0036]Basic Signal: Signal Type, which refers to a preset digital signal with editable parameters, including Function Signal and Recording Signal. Among them, the function signal is expressed by a mathematical relationship; the record signal is a set of data whose waveform amplitude has been recorded in advance and whose gain coefficient can be edited by the user. Both the function signal and the recording signal need to obtain the output amplitude (Output Amplitude) data by digital operation after the test signal or test step is formed. Multiple function signals form a function signal source (FunctionSignal Source); multiple recording signals form a recording signal source (Recording Signal Source); function signal sources and recording signal sources form a basic signal source library (Basic Signal Source Library).

[0037] Testing Signal: also known as Preset...
