GRATING CALIBRATION COMMANDS:
INIT-OFFSET Sets the offset value for the designated grating. Default values are 0 for gratings 1, 4
and 7; 1536000 for gratings 2, 5 and 8; and 3072000 for gratings 3, 6, and 9. The
limits on the settings are +/- 2500 for a 1200 g/mm grating. This corresponds to an
error of greater than +/- 5nm for a 1200 g/mm grating. The limits are adjusted for
grating groove density, e.g. error for a 600 g/mm grating is +/- 5000. The grating
density designator used with this command is grating# - 1.
E.G. 3072056. 8 INIT-OFFSET for setting offset on grating #9 - 3rd grating on
turret #3.
NOTE: This command requires a decimal point after the offset value.
INIT-SP750-OFFSET Same as INIT-OFFSET above except no decimal point is used after the offset value.
E.G. 3072056 8 INIT-SP750-OFFSET
INIT-GADJUST Sets grating adjustment value for the designated grating. Default values are 10000 for
all gratings. The limits on the parameter for this command are +/- 1000 for all
gratings. The grating designator used with this command is the grating # - 1.
E.G. 9993 1 INIT-GADJUST for setting gadjust on the second grating of turret #1.
NOTE: This command is to maintain compatibility with previous Acton SP
applications. For new applications, use the INIT-SP750-GADJUST command below.
INIT-SP750-GADJUSTSets grating adjustment value for the designated grating. Default values are 1000000
for all gratings. The limits on the parameter for this command are +/-100000 for all
gratings. The grating designator used with this command is the grating# - 1.
E.G. 999322 4 INIT-SP300-GADJUST for setting gadjust on the second grating of
turret #2.
MONO-EESTATUS Returns setup and grating calibration parameters for all gratings.
RESTORE FACTORY
SETTINGS Returns all parameters including grating calibration parameters to the original factory
calibrated settings. NOTE: This command will overwrite any calibration parameters
set by the user.
MONO-RESET Initializes monochromator. Necessary after using INIT-OFFSET,
INIT-GADJUST or INIT-SP750-GADJUST.
HELLO Same as MONO-RESET. Used to maintain compatibility with existing applications.
MODEL Returns model number of Acton SP monochromator.
E.G. MODEL SP-558
SERIAL Returns serial number of Acton SP monochromator. Format is 7 digits with the first
3 digits being the model #.
E.G. SERIAL 3060232
