23 Additional technical information about lightwave measurement
error analysis and calibration is available upon request from an
Agilent Technologies representative.
24 Crosstalk effects are included in the dynamic range and
dynamic accuracy specifications.
25 Optical connector repeatability, cable stability, and system drift
are not included. Transmission and transfer function measure-
ments assume a well-matched device that produces no reflection
from its input port.
26 These calibrations are verified with Agilent’s in-house NIST
traceable reference receiver.
27 Tracking accounts for switch repeatability and frequency response
differences between the measurement reference path and test path.
28 For electrical-to-electrical devices:
Return loss (dBe) = –20 log (
ρ)
Transmission (dBe) = 20 log (V2/V1) = 20 log (I2/I1) = 10 log (P2/P1)
29 Lightwave measurement uncertainty is defined as:
Warranted uncertainty = ((system errors)^2 + (random RSS
errors)^2)^0.5. Typical uncertainty is the RSS combination of all
system and random errors.
30 Uncertainty graphs below refer to relative flatness and modulation
bandwidth measurements. An absolute uncertainty value for a
specific data point can be calculated by adding 1.5 dB to the value
found on the uncertainty graphs.
