Tutorial 2: Measure in Optical Power Units
Tutorial 2: Measure in Optical Power Units
The analyzer display has the ability to show optical units referenced to the
input of the optical-to-electrical converter. This changes the channel and
marker readouts to watts/div.
1 Set the analyzer to a known state by pressing:
INSTR PRESET, Trg,Cal, CH1 EXT ATTEN responsivity value,
V/Watt
For example, the following figure shows 350 V/Watt entered. Notice the soft-
key label changes to CH1 RSPVTY (responsivity).
2 To use the markers to read optical power, press:
Markers, Y1 (--)
3 Adjust the marker line to the peak of the response. For example, the following
figure shows a peak optical power of 1.5 mW.
