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.

1 2 ... 37 38 39 40 41 42 43 44 45 46 47 ... 175 176
