Setting Up Acquisition Parameters

Before performing your test, you must set the acquisition type and

parameters.

There are three types of acquisitions in WDM mode:

 Single: Spectral measurement is performed once. The results are

displayed according to this measurement.

 Averaging: Spectral measurements are performed based on the

number of scans that you have entered for this parameter. The trace

will be displayed after each acquisition and averaged with the previous

traces.

 Real-Time: In real-time acquisition, spectral measurements are

performed continuously until you press Stop. No averaging is done for

spectral measurements. The graph and results are refreshed after each

acquisition.
