init.c - Acquiring Data

* Function name: acquire_data

* Parameters: none

* Return value: none

* Description: This routine acquires data according to the current

* instrument settings.

void acquire_data ( )

{

* The root level :DIGitize command is recommended for acquisition of new

* data when averaging is used. It will initialize data buffers, acquire new data, and ensure that

* acquisition criteria are met before acquisition of data is stopped. The

* captured data is then available for measurements, storage, or transfer

* to a PC. Note that the display is automatically turned off by the

* :DIGitize command and must be turned on to view the captured data.

write_IO (":DIGitize CHANnel1");

write_IO (":CHANnel1:DISPlay ON"); /* turn on channel 1 display which is */

/* turned off by the :DIGitize command */

} /* end acquire_data ( ) */
