VnmrJ Command and Parameter Reference VnmrJ 2.2D

AC1S-AC11S
Autocalibration macros (M)
Syntax: ACnS, where n is a number from 1 to 11.
Description: Performs automatic system calibration. When finished with the calibration
routines, the current probe file is updated. If the probe is new to the system (i.e.,
all values in the probe file are zero), system power levels are determined
followed by calibration. If power levels are listed in the current probe file, these
values are used. The macro AC1S determines 1 H pw90, AC5S begins 13 C
calibration, including decoupler power calibrations. AC10S performs 19 F
calibration, and AC11S performs 31 P calibration.

ACbackup
Syntax:
Description:
See also:
Make backup copy of current probe file (M)
ACbackup
Called by the autocalibration macros AC1S-AC11S to back up the probe file
after calibration ends. This macro is not usually called by the user.

acos
Find arc cosine of number (C)
Syntax: acos(value)
Description: Finds the arc cosine (also called the inverse cosine) of a number.
Arguments: value is a number in the range of ±–1.0 to +1.0.
n is a return argument giving the arc cosine, in radians, of value. The default
is to display the arc cosine value in the status window.
Examples: acos(.5)
acos(value):acos_val
