3.1.4. Stabilizer
The digiBASE-E has both a gain
stabilizer and a zero stabilizer; their
operation is discussed in more detail
in the MAESTRO User’s Manual.
The Stabilizer tab (Fig. 11) shows the
current values for the stabilizers. The
value in each Adjustment section
shows how much adjustment is cur-
rently applied. The Initialize buttons
set the adjustment to 0. If the value
approaches 90% or above, the amp-
lifier gain should be adjusted so the
stabilizer can continue to function
— when the adjustment value reaches
100%, the stabilizer cannot make
further corrections in that direction. The Center Channel and Width fields show the
peak currently used for stabilization.
To enable the stabilizer, enter the Center Channel and Width values manually or click on the
Suggest Region button. Suggest Region reads the position of the marker and inserts values into
the fields. If the marker is in an ROI, the limits of the ROI are used. If the marker is not in an
ROI, the center channel is the marker chan-nel and the width is 3 times the FWHM at this
energy. Now click on the appropriate Enabled checkbox to turn the stabilizer on. Until changed
in this dialog, the stabilizer will stay enabled even if the power is turned off. When the stabilizer
is enabled, the Center Channel and Width cannot be changed.
