Figure 1-6. E/O Characteristic Peak-to-Peak Repeatability
The above graph shows the worst case deviation across a 20 GHz span between any 2 units in a sample set
of 12.
E/O Frequency Response Error for Different Reflection Coefficients
A significant error term in this measurement is the electrical port match of the device under test (DUT).
The following table lists the measurement uncertainty as a function of DUT electrical reflection coefficient.
If you perform a response and match calibration, you can achieve values comparable to measurements of
devices with
ρ = < 0.25, as shown in “Relative Frequency Response Performance Data” on page 1-8.
Electrical-to-Optical Relative Frequency Response Versus ρ
Frequency Range ρ < 0.5 Specification ρ < 1.0 Specification
0.05 to 0.5 GHz ± 1.75 ± 3.10
0.5 to 11 GHz ± 2.05 ± 3.35
11 to 20.05 GHz ± 2.40 ± 3.40
