Measuring Opto-Electrical (OE) Devices
Keysight N4373D Lightwave Component Analyzer, User's Guide
Always perform an electrical calibration of the network
analyzer or load an existing calibration set before you make a
measurement.
For standard measurements, see "Electrical calibration for
single-ended measurements" on page 85.
For differential measurements (applies to 4-port PNA only), see
"Electrical Calibration for Differential OE Measurements" on
page 86.
For OE measurements the single-ended (SE), logical port 1 is
assigned to physical port 1 and the balanced (BAL), logical port
2 is assigned to the physical ports 2 and 3.
For OE measurements, the LCA sets up traces for S22, S21, S33,
S31 by default.
For more information, see "Differential Measurements (applies
to 4-port PNA only)" on page 59.
Before you make your first opto-electrical measurement, you
must initialise the OE measurement. You can see which
measurement is currently initialised at the top left of the trace
screen.
If you have already initialised the OE measurement, you can
connect your device under test and make the measurement by
pressing
or
Please refer to the user guide and online help for the network
