Correction Rng
Correction range: 1% (Ge) or 10% (NaI). This control selects the Gain Correction
range that can be provided to correct for drift. Select ±1% for a germanium detector or
±10% for a sodium iodide detector. This control can only be set via the MID Editor.
DSP Gain Parameters
The DSP Gain settings screen (Figure 9) for the 9660 contains the following controls.
Coarse Gain
Sets the device’s coarse gain. It’s best to choose the highest Coarse Gain which, com-
bined with the Fine and Super-Fine Gains, will produce the total desired gain.
Fine Gain
Sets the device’s Fine Gain multiplier.
S-Fine Gain
Sets the device’s Super-Fine Gain value.
The combination of Coarse and Fine Gain sets the overall system gain to match the re-
quirements of the detector and energy application; overall gain is continuously vari-
able from x2.0 to x1536. The Fine Gain factor is dependent on the Super-Fine Gain
(SFG) value. With the SFG set to 0.0000e
-2
, the Fine Gain covers a range of x0.4 to
x1.6. The SFG value adds to the Fine Gain factor and covers a range of 0.0000e
-2
to
3.0000e
-2
.
