Measurement apparatus and method for the adjustment of test/measurement parameters

摘要

An instrument is described for the measurement of optical and/or electrical signals, such as an optical time domain reflectometer (OTDR) or an electrical time domain reflectometer (TDR). The instrument includes a display to depict a waveform representative of measured signals, and can be operated by a few buttons, namely a start/stop button, a cursor-key and a select/confirmation-key. After adjustment of display parameters, almost the entire display is available for display of measured signals and data.
