Exciter Setup

dB reference switches the indication of levels between dBV and dBU.

Level [dB] defines the output level of the measuring system without considering external power amplifiers.

Voltage [Vrms] specifies the effective output voltage.

Level [dBFS] sets the level of the measuring signal in relation to the maximum output level. The highest value possible is 0 dBFS.

Furthermore, for measurements explicitly requiring the definition of an excitation signal, the measurement signal is to be selected via Exciter. When measuring frequency responses (Frequency response, LS sensitivity and Polar response) a reference signal suitable for the selected excitation signal is required. For frequency responses the excitation signal needs to fit a complete FFT-length, which means the number of samples must be a power of two. In case no suitable reference is to be found, a new reference measurement can be carried out using the corresponding reference menu.
