Abstract

An apparatus for the determination of the magnitude of a noise (TDUT) of an electronic object to be measured (2) includes a sine signal source (1), which generates a sine signal (Sin) for input into said object to be measured (2) and a level meter (3) for the measurement of a power level at the output of the said object to be measured (2). In accord with the invention, the level meter (3) possesses a sine power detector device (31) for the capture of a sine power level ({circumflex over (P)}sin) and has a noise power level detector device (32) for a separate capture of a noise power level ({circumflex over (P)}noise).
