6.2.2 Manually Accumulating Spectra

from Multiple Acquisitions

You can manually accumulate spectra from different

acquisitions to improve resolution and signal-to-noise ratio of

your data.

Accumulating

To manually accumulate spectra from multiple acquisitions:

1. Acquire a spectrum and evaluate the data as described

in Section 6.2.1, Manually Acquiring,

Evaluating, and Saving Spectra.

2. When acquisition is complete, do not save the data.

3. If the spectrum is acceptable, select Accumulate

Spectrum from the Acquisition menu or click to

accumulate the spectrum.

The software adds an Accumulated trace to the

Spectrum window and copies the Current trace in the

Accumulated trace.

If the spectrum is not acceptable, start a new

acquisition. The Current trace will be overwritten by the

new acquisition.

CAUTION

If you change any instrument settings, with the

exception of Shots/Spectrum and laser intensity, the

Accumulated trace is automatically cleared before the

next acquisition.

4. Repeat step 1 though step 3 to acquire and accumulate

additional spectra. Each spectrum you accumulate is

averaged with the existing Accumulated trace.

NOTE: If needed, select Clear Accumulated trace

from the Acquisition menu or click .

5. When the data is acceptable, select (click on) the

Accumulated trace.

6. Select Save Spectrum from the Acquisition menu.
