Writing the Waveform of the Light Source Input to the Optical Filter on Trace A
1.
Input the emitted light from the light source that is input to the optical filter into the
instrument.
2.
Press TRACE followed by the ACTIVE TRACE soft key, then select A.
3.
Press the VIEW A soft key and select DISP.
4.
Press the WRITE A soft key. Trace A enters write mode.
5.
Measure the light source waveform according to measurement conditions
matching the light source waveform.
(For details on the measuring procedure, see chapter 5, “Measurement.”)
6.
Press the FIX A soft key under TRACE. Trace A enters fixed mode.
Note
If all traces from trace A to trace G have been set to fix mode (FIX) as a result of this action, a
warning is displayed. However, this does not pose a problem because trace B is set to write
mode in the next step.
Writing the Waveform of the Output Light from the Optical Filter to Trace B
1.
Input the emitted light from the light source to the optical filter, then input the light
that is output from the optical filter into the instrument.
2.
Press TRACE followed by the ACTIVE TRACE soft key, then select B.
3.
Press the VIEW B soft key and select DISP.
4.
Press the WRITE B soft key. Trace B enters write mode.
5.
Measure the waveform of the output light with the same measurement conditions
used for measuring the light source waveform.
Writing the Difference between Traces to Trace C
2.
Press TRACE followed by the ACTIVE TRACE soft key, then select C.
3.
Press the VIEW C soft key and select DISP.
4.
Press the CALCULATE C soft key.
5.
Press the LOG MATH soft key. The math function selection menu is displayed.
6.
Press the C = A-B (LOG) soft key. The waveform which is obtained by subtracting
the trace B waveform from the trace A waveform is displayed on trace C.
