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.
