Abstract:

The LIGO global diagnostics system (GDS) provides diagnostics test capability for performing stimulus-response tests. Diagnostics tests are divided into five groups: (i) sine response tests which include multiple stimulus and multiple response, harmonic distortion and two-tone intermodulation, (ii) swept sine response which determines transfer functions, (iii) FFT tools which perform power spectrum estimates and cross-correlation measurements, (iv) time series measurements which measure the response to a trigger signal, and (v) pseudo-random stimulus response tests which utilize wide-bandwidth excitation signals.
