Qe65000 spectrometer and dark spectra

Hello everyone,
I'm working with an Ocean Optics QE65000 spectrometer and am trying to automate the process of acquiring and subtracting a dark spectra in the same way that SpectraSuite does. Does anyone know of a VI that does this without having to manually take a spectra with the shutter closed on the spectrometer? I tried using the Ocean Optics Spectral Processing vi but it doesn't work with the WE65000 specifically. I also searched their site for any drivers or vi's that have a dark spectra acquisition feature.
If there isn't a VI for this, is there a way to call up an external program from LabView and tell it to run? For example, to call up SpectraSuite, tell it to acquire a spectra and subtract the dark spectra, save the text file, return to LabView and read the SpectraSuite text files.
I'm relatively new with LabView, have only been working for two months or so, but I'm willing to learn G and dig through the code if necessary. I just don't know where to start.
Thanks in advance!

Hi Michael,
The first thing I would try is using the instrument driver that is available for download here. I don't personally have this driver installed so I don't know if it will do what you want, but it is a good first step.
If this doesn't work, there are several other options. If this SpectraSuite program has an ActiveX interface, you should be able to call into it through LabVIEW. Also, the SpectraSuite software might call into some dlls that you can use from LabVIEW. You would do this through a call library function node.
Let me know if any of these things work for you!
Thanks,

Labview code to trigger and scan spectra from HR4000 spectrometer?

has anyone used labview code to trigger and scan spectra from HR4000 spectrometer? When I use one of the device drivers (Spectral Acquisition.vi), i miss lots of trigger when I run it for more than 100 iterations?
I was wandering if anyone is working with it or had in the past and if you could share your insight.
Thanks

Inconsistent times are one thing, overall slowing down is another, although they may have common source. I guess it is the XY plot in your case. Do you have it AutoScaled? If so, try turning autoscaling of both axes off.
Secondly, I don't quite understand the reason for the inner loop with number of iterations = constant 1. What happens if you remove the loop? I understand you want to change the number of iterations in future, but let's test the simplest things first. Removal will require indexing the Wavelength array explicitly with an apropriate block. By the way, it is customary that you EITHER define the number of iterations of a FOR loop by connecting the N input OR by indexing of an input array - NEVER both at the same time. Maybe, changing the multiple XY plot into a single XY plot won't be necessary, maybe it will, try for yourself.
Thirdly, I suggest you try enclosing the XY plot block alone in a case structure (say, in its TRUE window) and set the true condition to occur at some fraction of the total iterations, not every cycle. You do this using the index "i" of the main iteration loop, calculate modulo something (e.g. 10) and test if it is true or false. This way you update the XY plot every 10th iteration only and by choosing different modulo divider you can test, if the plot's display is or isn't the beast slowing things down.
Finally, I suspect it is not necessary to use a Local Variable of the seconds 2 indicator. How about simply wiring the output of your To-double block to the input of the subtraction block? That should let you remove seconds 2 local variable with no harm done.

Why is my iPod Touch 4G screen flickering light and dark?

my iPod Touch 4G screen flickering light and dark all the time?!?! I also have this problem where at the VERY bottom of the screen, Theres this white bar that keeps flickering on and off!! PLEASE HELP ASAP!!!

Alternating light and dark blue screen on trying to start up

Today, on trying to restart after an Intego VirusBarrier update, I got stuck with just a blank blue screen alternating light and dark. I still can't restart on my internal drive, but after starting up from the install disc have managed to restart from a cloned OS 10.5.5 on my external drive. When I try to restart from the internal drive I just get the alternating shades of blue screen and nothing else - no error message, no question mark, just the pulsating blue screen - HELP!!!!

Thanks but that wasn't it. I replaced the battery and reset the PMU, still no luck. I've tried hooking up an external monitor still nothing, in doing all of this the person helping and I noticed that when you push the button on front to power up it doesn't light but I'm also not getting a start up chime, only the click of the hard drive then in pushing the button to power it off the light will blink and I think it is shutting down. Any other suggestions.
Thanks

Light and dark solid grey vertical lines appear randomly on screen

This has happened about 4 times in the last couple of months, when these light and dark solid grey lines appear on my screen, I have to turn my computer off by holding down the power button and rebooting it, it fixes the problem for the time being. These lines appear randomly, they have appeared when using Photoshop CS6, also when just using the internet, listening to Pandora. 1 out of the 4 times these lines appeared, there was a ticking/clicking noise... I took it to the local computer shop and they did tests on it twice and found nothing.

Satellite L450 - Webcam picture is grainy and dark

I dont know if its the web cam on this model is not very good but the web cam is extremely grainy and dark. I have tried all usual playing about with settings but nothing improves the image i.e.,grainy lack of any colour and just generally really poor and the laptop is brand new.
If anyone has a good clear picture please let me know seems a shame because I am happy with the rest of the system.
Thank you in advance

In what image mode are you working? Creating a document in CMYK and then displaying it on a screen, which is RGB, may be the issue.

Why does the same RGB color appear lighter in one ai file and darker in another?

Why does the same RGB color appear lighter in one ai file and darker in another?? I want to use the more vibrant color, but when I try to reproduce the same RGB color code in another Adobe Illustrator (ai) file, it shows up darker. I printed the two files out, and you can see the difference in the print too. I exported the color orginally as an eps file from an ArcGIS map.
Any insight is greatly appreciated!
Anne

You illustrator files may have different color profiles attached.
Set to show your color profile in the bottom left of each document by using the flyout menu >> show >> document color profile
Then you can use edit >> assign profile to get them the same
Yours are quite far off for RGB (which are usually close to each other for many profile due to wide gamut). I question as Jacob did if one of your documents are in CMYK mode. Look in parenthesis after the document name at top of window.
Check if view > proof setup is the same (do not use the uncoated profile as in my screenshot, that was only there cause of my testing)
Make sure view >> proofs colors is checked or unchecked for both.
To get them to print the same, check these settings are the same
Sorry for all the screenshots, but hopefully one day we will see Adobe's complex color management united all in one window.

Help me solve color and dark print issue with a new monitor recommendation!

I know, I hate "surveys" too. I'm thinking of attacking my color and dark printing issues w\LR and CS4, by investing in a new monitor. I currently have an 20' early edition Apple Cinema Display. The monitor is the last hardware (software) item in my current upgrade cycle. From those folks who are NOT having color or print problems, what displays are you using (or would recommend)? Ah, and price is an issue. Apologies in advance to those who think this is not appropriate use of the Forum.

Monitor calibration is the first port of call. Sometimes changing one item in a system is enough to show up a colour management issue. You suggest that the monitor is the last item in your upgrade cycle, what all have you changed? Computer, printer? There may also be a setting you have failed to set when you installed the new software, eg. have you remembered to set relative colorimetric with the black point compensation box ticked, disable colour management in your printer driver and put an appropriate colour profile for your monitor onto the new computer? You also need the correct profile for your printer/paper combination set up in Photoshop.
If you haven't calibrated your monitor, that on its own will give you poor prints, but all the other bits are needed also.

using cs6 pencil and my strokes overlaping and dark. how do I stop this?

Check the tool options bar and make sure the opacity is 100% and the mode is Normal.
If you need to paint with reduced opacity or a blending mode with either the brush tool or pencil tool, using a separate layer and adjusting the opacity or blending mode of the layer works better.

My i860 canon printer is suddenly printing color pictures with light blue and darker blue horizontal

My i860 canon printer is suddenly printing color pictures with light blue and darker blue horizontal lines. I have changed the cyan blue cartridge and the problem still exists. Does anyone know what the problem is? Thanks.

Hi CSM,
We can perform a print head cleaning and alignment on the printer to try and resolve the issue. To do this, please follow the steps below:
PRINT HEAD CLEANING
With the printer powered on, press and hold the <Resume/Cancel> button.
<1> Resume/Cancel button
When the power lamp blinks once, release the button.
Note: The power lamp will blink and print head cleaning will start. The cleaning completes when the power lamp stops blinking. (It will take about 30 seconds to a minute for the power lamp to stop blinking and remain lit solid green.)
PRINT HEAD ALIGNMENT
Confirm that the printer is powered on, and load Letter-sized white plain paper in the sheet feeder.
Note: If paper other than Letter-sized white plain paper is loaded, print head alignment cannot be performed properly.  The automatic print head alignment must be performed from the Automatic Sheet Feeder on the top of the printer. It cannot be performed from the cassette.
Press and hold the <Resume/Cancel> button, and release it when the Power lamp blinks four times. (The Power lamp will start blinking and pattern printing will start.)
Print head alignment will start automatically as the following pattern is printed.
Note:  Please wait approx. three minutes until printing is completed.
Hope this helps!
