SET_ZERO_WIDTH
chans
Sets the width in channels for the stabilizer zero peak. The 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 gain stabilization can be enabled. The absolute minimum width for the
peak is 3 channels. See also SHOW_ZERO_WIDTH, SET_ZERO_CHANNEL and
SHOW_ZERO_CHANNEL.
SHOW_ACTIVE
Returns a 1 if the digiBASE is active (i.e., acquiring spectral data) or 0 if it is not active.
Responses:
$C00000087<CR>
Not active.
$C00001088<CR>
Active.
SHOW_CONFIGURATION
Returns a record that indicates the hardware configuration of the MCB. The record contains
information about the number of segments in an MCB device (always 1 for the digiBASE),
and the current conversion gain for each segment. The record is organized as follows:
$J0102400001aaaaa00000[65 zeros here for total of 75 zeros]00000ccc
where
aaaaa
represents the conversion gain for the one and only segment in the currently
selected device, and
ccc
represents the record checksum. See Section ? for more information
about response records and checksums.
SHOW_CONFIGURATION_MASK
Returns two masks, the first of which can be “anded” with data from the MCB to clear the
ROI bit from the data. When the second mask value is “anded” with data from the MCB, the
data bits are removed and only the ROI bit remains.
Response:
CONF_MASK 02147483647 02147483648
SHOW_DEVICE
Shows the currently selected device. Always 1 for the digiBASE.
SHOW_FEATURES
Responds with four 32-bit masks indicating which features are present in the MCB. See
Appendix 3.4 for a complete description of each bit in the mask.
Example Response:
FEATURES 02149587261 01619623948 02175271168 00000000000
SHOW_GAIN_ADJUST
Returns percentage adjustment that has been applied by the stabilizer.
