

Sensitivity

is dened as the signal level that is equal to six times the RMS

value of the noise. Displayed sensitivity values are nominal. Slightly lower

values may have to be entered to achieve specied sensitivity.



Dynamic Range

is a measure of the ability to see low-level signals that

are located very close (in wavelength) to a stronger signal. In electrical

spectrum analyzers, this characteristic is generally called shape factor.
