6.3.6. Subtract...
The Subtract function (Fig. 41) subtracts a constant from each channel in the buffer. This func-
tion is useful if small peaks are present on a large, constant background. The background can be
subtracted off to get a better look at the peaks.
6.3.7. Normalize
The Normalize function transforms the data in the buffer by dividing the data in each channel
by the pass count and rounding that value off to the closest integer (see Fig. 42). This command
changes the pass count to 1.
6.3.8. Marker
Marker reports the current marker position on
the Supplementary Information Line near the
bottom of the display (see Fig. 43).
By default, the marker is reported at the center
of the channel. The marker position is displayed
at a much higher precision than on the Marker
Information Line.
In the external dwell time mode, the marker posi-
tion is displayed in channels. In the internal dwell
time mode it is displayed in time. If the spectrum
is calibrated, the marker position is also displayed
in calibrated units. In all three cases, the closest
channel number is also included on the Supple-
mentary Information Line.
If a region is selected with the marker, the width of the region is displayed, in time or calibrated
units, instead of the single marker position.
