amplitude
The relationship between Amp and Ofs is:
Amp
≤
Ofs
Ofs range: A to (2A
max
– A),
where A
max
is the value listed in the amplitude table
Notes:
Unless otherwise noted, specifications listed in table apply for standard 1480-1620nm or 1280-
1340nm operation at 23±5°C, at power levels >
−
25 dBm.
1.
Optimal sampling rate ranges depend on data collection/display mode and setup. Some
examples:
Externally triggered measurement:
Sampling rate can be up to 4M points/s.
PolaView Poincaré sphere mode with trace sensitivity = 0: Sampling rate should be
≤
500K
points/s for best results.
2.
Bandwidth may change at lower power levels due to automatic gain control.
3.
Accuracy depends on input SOP variation speed. See SOP accuracy specification for input
SOP variation up to 10
π
/s.
