Lynx II Genie 2000 Acquisition Window Adjust
From Genie’s Start menu, activate the Gamma Acquisition and Analysis (GAA)
application, then open the datasource for the specific instrument. To open a datasource,
select File | Open Datasource, then select the “Detector” option in the Source box.
Next, select the datasource file and then Open.
If the Detector list is empty, the likely cause is that no MCA definitions exist in the run-
time database, or that the VDM's key has not been detected.
The Adjust dialogs are found under the MCA menu in the Gamma Acquisition and
Analysis (GAA) application.
In the following Adjust Screen discussion, the MCS Adjust Screen and the associated
selection button are available only if MCA Input #2 was selected as the MCA Input
number when setting up the MCA controls in the Devices | MCA screen of the MID
Editor or MID Wizard. If MCA #1 was selected then the MCS selection button and adjust
screen are hidden from view, and only the PHA settings will be presented.
Notes: If you get a “Required Hardware Unavailable” error, the likely causes are you may
have selected the wrong data source for the instrument; there is a problem with the
communication interface (check the cables); the instrument power is off; or, the
instrument IP address was incorrectly entered when configuring the device. For
this case, the problem must be corrected before the data source can be opened.
If you get a “Hardware Verification Error” there is a mismatch between the MID
Definition setup and the hardware configuration. Likely causes are the High
Voltage Power Supply configuration or other hardware settings that have been
changed. You can choose to accept or not accept the verification error in the
associated dialog box. If you select NO, a RED error box will appear in the top left
corner of the Acquisition and Analysis window. You can determine the source of
the verification error by looking at the Status Page, which you can access by
clicking MCA | Status. The problematic item will be marked with an asterisk (*).
The following section describes those parameters for the Lynx II that can be accessed
from the acquisition windows’ Adjust dialog screen. Select the MCA | Adjust menu
options to access these screens.
Note that the Adjust screen for given hardware within the Lynx II may be composed of
more than one Adjust screen; when additional screens are present, the Next/Prev buttons
can be used to navigate them.
Stabilizer
The Stabilizer controls are accessible only from a PHA datasource. The datasource type is
defined during the MID Editor or MID Wizard session by selecting MCA Number 1 for
PHA or Number 2 for MCS.
The Stabilizer control in the Adjust dialog provides access to a set of parameters used to
adjust the Spectrum Stabilizer.
