Harmonic Distortion

The SR760 and SR770 are single-channel 100 kHz FFT spectrum analyzers with a dynamic range of 90 dB and a real-time bandwidth of 100 kHz. Additionally, the SR770 includes a low-distortion source which allows you to measure the transfer functions of electronic and mechanical systems. 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.

High Dynamic Range

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 distortionof the SR760 and SR770 allow you to see signals that would be buried in the noise of other analyzers.
