Pre and Post Acquire Strings
To allow the user to override analytical conditions or to customize the acquisition procedure the user can define pre acquire and post acquire strings. These strings are only applicable to the JEOL 8900 instruments. The commands are those commands allowed by the instrument (see vendor documentation).
For example, PB OFF for JEOL 8900. Multiple commands may be sent to the interface by separating the command with commas. For example “PB OFF, LAMP OFF” for the JEOL 8900.
The pre acquire string is sent to the interface after all analytical conditions, magnification and beam mode commands have been sent and just prior to the removal of the faraday cup. The post-acquire string is sent after the acquisition is completed.
