5.4   Typical Spectral Noise

The  typical  noise  spectrum  was  measured  using  an  electrical  spectrum  analyzer  (resolution

bandwidth 10 kHz, video bandwidth 10 kHz). The optical input

 

of the detector was blocked. The

black curve ("Reference") was measured with the same setup and the detector switched off ,

i.e., it represents the measurement system’s noise floor.

Typical Spectral Noise APD110C

Typical Spectral Noise APD120A
