RS232 Commands . 135
<ms> is a single character integer code representing current
monochromator selection (see $MX command).
<mq> is a single character integer code representing current
monochromator selection qualifier (see $MQ command).
<dc> is a single character integer code representing current data
collection mode (see $PH command).
<fl> is a single character integer code representing current filter
type (see $FL command).
<ex.wavelength> is fixed format (xxx.x) representing the
excitation monochromator position at the start of the scan in nm.
<em.wavelength> is fixed format (xxx.x) representing the
emission monochromator position at the start of the scan in rim.
<speed> is a 4 digit integer representing speed in nm/min. A
leading minus is given for negative speeds.
<response> is a 3 digit integer representing current filter
response number.
<ex. slit width> is fixed format (xx.x) representing the excitation
slit width in nm.
<em. slit width> is fixed format (xx.x) representing the emission
slit width in nm.
<max.points> is a 5 digit integer representing the maximum
number of real data points that may be returned in the scan.
<data.int> is fixed format (xxxx.x) representing the abscissa
interval between points in nm.
Command: SCAN DATA INTERVAL
Syntax: $SI interval
Description: Sets data output interval for subsequent scans. Interval is in
range 0.1 to 5 nm and is rounded to nearest multiple of 0.1 nm.
Current interval is returned if no parameter specified. Power-on
default is 0.5 nm.
