changing to relative power levels, the controls are all scaled relative to the channel which is set to the highest
output power; in this way, the actual
spectrum
as shown by the controls’ relative positions to each other can be
seen regardless of the RS-7’s Main Output Power.
1e. All Off (Reset Spectrum To Zero)
This button will set all the channels to
OFF
(0), thus
removing the current output spectrum completely
. If you
merely want to turn the RS-7’s output off but
want to maintain the spectrum,
instead use the Main Output
Power Level control (
1b
) or type zero into one of the power level boxes (
1a
); in this case, the RS-7 “remembers”
the current spectrum in spite of the fact that all of the Individual Channel Power Level controls (
1b
) appear to be
set to OFF (in other words, using the All Off button
really
turns all the channels off, and you won’t be able to set
the Main Output Power Level to anything besides zero because
there is no Output Spectrum for it to use
. Move
at least one Channel Power Level Control to start creating a new spectrum).
1f. Spectral Plot
The white line shows the RS-7’s current Output Spectrum, and the individual channels’ spectra are shown in
their approximate color, with infrared channels displayed as deep reds, if Plot All (
1h
) is checked. Additionally, if
the Target Spectrum is visible (
3b
), it will be shown as a blue line, with graphic brackets representing the
effective Wavelength Range (
3n, 3o
) for spectral operations. The wavelength range of the Spectral Plot itself can
be adjusted by changing the Start and End wavelengths (
1g
).

1g. Spectral Plot Wavelength Range
The starting and ending wavelengths of the Spectral Plot can be changed in order to display just a portion of the
spectrum.
1h. Plot All Chan
If this is not checked, only the current Output Spectrum (white line), and optionally the Target Spectrum (blue
line)
(see Section 3.3) will be plotted. Checking this box will include all of the individual channels’ spectra in
approximately the color of each channel, with infrared channels all shown in red.
1i. CIE 1931 x,y Color Chart
The chromaticity of the RS-7’s current Output Spectrum is shown on the Color Chart as the little black circle.
Note that the Color Chart also accepts input
; you can click anywhere on the chart and the RS-7 will attempt to
modify the current Output Spectrum using a color-matching algorithm that uses the tristimulus curves as
weighting functions to add or remove energy in the three X, Y, and Z regions to arrive at the new chromaticity.

1j. Command/Status Bar
ASCII Commands sent to the RS-7 over the COM port, and the responses received back from the unit, are
displayed in this box. In the event there is an error, the box will briefly flash red to draw attention to what went
wrong. See SECTION 4 for a description of the each of the ASCII commands used to operate the unit, and
Section 4.7 for an explanation of the “?nn –“ error codes at the end.
1k. Presets
The RS-7’s current output state can be stored as a preset.
To load an existing preset
, click on the arrow and
select a preset from the list.
To save the RS-7’s current output state as a new preset
, click the Store Preset
button, select the preset # where you want to store the preset by clicking on the arrow and selecting from the
