SpectralLED® RS-7 USER MANUAL Page 394.2.6 - SCA - Scan Thru Individual Channels/Channel Groups by Increasing WavelengthActivates channels one at a time at the NPL power in order of increasing centroid/peak/center wavelength (seePTY). If two or more channels share the same wavelength, then they are output in order of increasing FWHM.The currently operating channel number(s), wavelength, FWHM, and output (ir)radiance in μW/cm 2 orμW/cm 2/sr (see CTY, IRR) are reported each time, and are not returned until the RS-7 output has settled to anaccuracy of STP percent. White channels will follow the monochromatic channels in order of increasing CCT.Syntax:SCA [startWL] begin scan starting at channel nearest at or above wavelength [startWL]SCAN move to next higher wavelengthSCANR move to next higher wavelength & wrap around to shortest wavelength after reaching the endSCAD [delay] execute SCANR repeatedly with a delay of [delay] milliseconds between commands, ESC to stopExamples:sca360 begin scan at 360nm, shortest possible wavelength14,382.3,12.923,56.141 RS-7 finds channel #14 is the closest at 382.3nm, and activates it at NPL powerscan move to next higher wavelength8+49,387.6,14.512,49.712 next step higher in wavelength is channels #8 & #49 (grouped) at 387.6nm…scan move to next higher wavelength51,983.4,62.512,15.633 this would be approximately the highest wavelength found in the standard RS-7scan move to next higher wavelength31,2668,0,82.451 channel #31 is a white LED with a CCT of 2668Kscan move to next higher CCT22,6311,0,94.561 channel #22 is a white LED with a CCT of 6311Kscan move to next?02 – argument out of range error results, indicating we’re past the end of the LED wavelengths/CCTsscanr move to next with repeat/wraparound14,382.3,12.923,56.141 automatically wraps around back to shortest-wavelength channel4.2.7 NPL - Nominal Power LevelDetermines the default power level (as UNI 2, 0 – 100% power) as used by the SCA (Scan Channels) command.The default NPL is 70%. Also, this determines the power level for which LIN reports a channel’s nominalwavelength and FWHM.Syntax:NPL report current Nominal Power LevelNPL [%] set Nominal Power Level to [%] (0 – 100)Examples:
