The SRS SR760 is a single-channel 100 kHz FFT spectrum analyzer with a dynamic range of 90 dB and a real-time bandwidth of 100 kHz. The speed and dynamic range of these instruments, coupled with their flexibility and many analysis modes, makes them the ideal choice for a variety of applications including acoustics, vibration, noise measurement and general electronic use. The SRS SR760 has 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 SRS SR760 allows you to see signals that would be buried in the noise of other analyzers. Specifications.
