71
SET_TRUE_PRESET ticks
Sets the true-time preset to the specified number of ticks (20 ms/tick). During data acquisi-
tion when the true-time counter reaches the preset number of ticks, the preset is complete
and the acquisition is stopped. Setting a true-time preset to 0 ticks disables the preset. See
also CLEAR_PRESETS and SHOW_TRUE_PRESET.
SET_ULD value
This sets the upper level discriminator to value, in channels.
SET_UNCERTAINTY_PRESET percent
Sets the uncertainty preset to the specified value in percent. Percent is a floating point value
from 0–99.9999. See also SHOW_UNCERTAINTY_PRESET.
SET_WINDOW [start, length]
Sets the window of interest to the specified start channel and number of channels. The chan-
nels of spectral data in the window of interest are affected by commands such as CLEAR,
SET_DATA, and WRITE. If neither start nor length is provided, the window is set to the
maximum size allowed by the conversion gain specified. The window of interest is always
set to the maximum size after a SET_DEVICE command or a SET_SEGMENT command.
SET_ZERO_ADJUSTMENT value
Sets the zero stabilization adjustment to an arbitrary value from
!
65535 to 65535. The
total range of the adjustment value represents ±256 channels. This adjustment is usually
only made by the gain stabilizer, and reset to 0 with the INITIALIZE_ZERO_
STABILIZATION command. See also SHOW_ZERO_ADJUSTMENT.
SET_ZERO_CHANNEL chan
Sets the center channel for the stabilizer zero peak. If a zero channel is chosen such that the
beginning channel or ending channel would be below channel 0 or above the maximum
channel, as determined by the conversion gain, the zero peak width is reduced until the peak
fits the device boundaries. A zero channel and width must be set before zero stabilization
can be enabled. See also ENABLE_ZERO_STABILIZATION.
SET_ZERO_WIDTH chans
Sets the width in channels for the stabilizer zero peak. The zero width must be chosen such
that the beginning channel is no lower than channel 0 and the ending channel is no higher
than the maximum channel as determined by the conversion gain. The zero channel and
width must be set before zero stabilization can be enabled. The absolute minimum width for
the zero peak is 3 channels, and the absolute maximum width for the zero peak is 256 chan-
nels in Gauss mode. In point mode there is no maximum peak width, though the chosen
width must allow the peak to fit within the device’s channel limits as stated above.
