概要（Overview）

The SR760 and SR770 have a dynamic range of 90 dB. This means that for a full-scale input signal, the instruments have no spurious responses larger than −90 dBc (1 part in 30,000). Even signals as small as −114 dBc (1 part in 500,000) may be observed by using averaging. The low front-end noise and low harmonic distortion of the SR760 and SR770 allow you to see signals that would be buried in the noise of other analyzers.
