AES Alignment Routine for Surveys when using an Analog Multiplier Supply
The following procedure determines the correct multiplier voltage when you are
using an analog (for example, 20-075) multiplier supply to acquire an AES
survey.
- Select the New Alignment command from the Acquisition menu, or click on the
New Alignment button in the main toolbar.
- Set the Upper Limit and Lower Limit energy settings in the Alignment Settings
dialog box to sweep the last 100eV of the region. For example, if you are
acquiring a survey from 30 to 1030eV, enter 930 as the Lower Limit and 1030 as the
Upper Limit.
- Click on the Acquire button.
- Increase the multiplier voltage until you have 80% to 90% of the maximum allowable signal for your V/F preamplifier . This is the multiplier voltage your system will use to acquire a survey.
Continue with the procedure for acquiring an AES survey.
