Trigger Functions
Note
Since trigger data is output immediately to the serial interface, it is
possible to use the trigger functions to drive a terminal, modem, or a
line printer (if a serial-to-parallel converter is available) connected
to the serial interface.
If the trigger output data is not formatted, the data will be comma
delimited and returned in the order of time, magnet field, magnet current,
and magnet voltage. Only the data enabled for output will appear in the
trigger output string.
4.5.8.2 Trigger Commands and Queries
‡
*ETE < enable_value >
Enables trigger functions according to the definitions in Table 4-6. To
enable the trigger functions, you must write a decimal
< enable_value >
which corresponds to the binary-weighted sum of the functions you wish to
enable. For example, to enable formatted output of the time, magnet field,
and the magnet voltage to the serial interface, send the command:
*ETE 109;
The return data in the serial output buffer would appear as (with the field
units selected as kilogauss):
00:03:14.85, FIELD= 20.002 kG, VOLTAGE= 2.05 V
‡
*ETE?
The *ETE? query returns a decimal sum which corresponds to the binary-
weighted sum of the trigger functions enabled by the last *ETE command.
‡
*TRG
Initiates trigger output to the enabled interfaces for trigger functions.
