Same as in elog #110, but now the amplitude is proportional to frequency squared:
ampl = (x/x[0])**2
xx = multi_band_noise(bands, ampl, T=20, fs=65536)
n = AWGNoiseStream(4e-4*xx, channel='X3:CR1-ESD_EXC', rate=65536)
n.start()
Noise stopped at 8:27:40am LT.
Turbo pump off and spinning down at 9:37am LT. Pumo completely stopped at 11:15am LT
Openend the chamber and removed the sample at ~11:20am LT |
