Proposal to expand the scope of an analog pathway for a USB-6009 or similar device

I'm sure that someone thought to how reduce an analog input voltage to an acceptable range for the data acquisition device that they use. I'd be interested to see what has already been written on the subject. In the meantime, I enclose an exel sheet spread detailing my own approach to this situation.

1 SCXI chassis of NOR

2 OPTO20

3. Non-inverting op-amp circuit.

Signal conditioning circuit is now quite cheap and reliable.  For me, it is better to buy something off the shelf, because in the future it will be easy for people to follow my design as well.

  • Digital and analog inputs simultaneously - NI USB-6009 and NI USB-6212 - ANSI C


    I'm reading at all times and at the same time analog and digital inputs. Digital and analog samples must be sampled at the same clock and acquisition should be started (triggered?) at the same time (I don't want, after some time, analog reception more digital samples - the opposite is also true).

    -Is it possible sync analog and digital acquisition in the paintings?

    -If so, how?

    Thank you

    Hello tcbusatta,

    Two of these modules, USB = 6008 and USB-6212, support only timed software inputs and digital outputs.  This means that you cannot define material timing (like finished sampling or continuous) for these modules.  Digital lines can be retrieved or written once to each call DAQmx read.

    This means that you will not be able to get any type of synchronization tight between the analogue and digital channels.  You will need a Board such as the NI USB-6341 in order to synchronize the AI and DI closely.

  • Why is the selection of the mode disabled in max for NIDAQ-USB-6009?

    I try to use NOR-USB-6009 AO to generate the sinusoidal signal.

    (1) I want to use MAX, but the selection of the mode and frequency are all disabled in the "Analog output" section

    (2) I find a VB example to generate the sine wave, but I received an error message.

    I want to know if the OR-6009 function support limited or not...?

    The attachment includes the screenshot.

    Thank you very much!



    Yes. Timed software means that the appliance has no internal clock or the buffer. You call the AO write with data point. Then you call AO write later with another data point. Repeat until cooked. This means that the maximum rate of update of the AO is approximately 100 hertz or a little faster. It also means that there is a lot of jitter of synchronization due to latencies of the OS at speeds like that.

    Think about AO on the USB-6009 case as a parameter Variant sometimes of continuous tension for your system.

    I have no idea why this phase shift occurs.

    Any information is welcome. Thank you for reading.

    An image file will not help. Post your real VI. If Firefox does not work, use explore or Chrome to fix your VI (s)!

    You have here a Subvi, I don't see what's inside and how it is configured. In addition, this while loop is ridiculous: there is no button to stop him running. Never use the red button to abandon for a normal shutdown of a VI!

    Why you have configured NChan NSample? Measure a unique signal, Yes? For example, use 1 channel only.

    Edit: why do not you play first with an example given, delivered with LabVIEW?

    Your LabVIEW, go to the Help menu--> find--> material and output examples--> DAQmx--> entry--> and open 'Input.VI - constant tension!

    This VI allows to enjoy your analog signal.

  • Add to contacts to work the perimeter, also citing maps in the scope of work

    I have a native app for BlackBerry 10 for the container/perimter of work.

    I would call add to contacts and also able to summon cards in container/scope of work.

    If I have an application in the work bowl, all invoke applications will happen in the container to work alone? When I make the call, his phone calls in the container to work. Now I need to access email, calendar, cards, add to contacts, and let me know that everything an application in the perimeter of work container will call PIM functions within the perimeter of work only.

    I want examples of code to add to contact and invoking maps in the perimeter of work scope app...

    Really, any help would be apprciated.

    Invocation framework is restricted within the perimeter you call. Therefore, if your application is in the scope of work, you can only call call targets that are also available in the scope of work.

    For contacts and calling card, please refer to this page:


  • All the benefits of trading on a full frame Canon 6 d to the top of a 60 d for horse photography?

    Hello, I am considering upgrading my Canon 60 d to a full frame (6 d), I usually shoot horses in action, and not profiles of head using a Canon 70-200 L IS lens. I would be interested in your comments about whether if the cost would benefit me with this type of photography. Also extra lens suggestions would be appreciated.

    I do a ton of equestrian photography.

    I use a pair of 7 d for the vast majority (90% or more). Those who have essentially the same sensor and high ISO capability as your 60 d, just a slightly more sophisticated (but more sensitive) autofocus system and superior pace. I also have a 5 d Mark II that is proven sometimes useful in low-light situations, but I use it much less than cameras of the harvest. The 5DII can do a higher than the 7 d ISO stop (a 6 d ISO offer slightly higher than the 5DII, as well as the light focusing very low ability).

    Mainly, I'd rather have the 'additional' scope of the cameras of culture as the ISO capabilities of full frame. My most used lenses are the 70 - 200/2.8, 70 - 200/4 IS, IS 300/2.8 and 300/4 IS. I also wear and sometimes use 28-135 IS, 10-22mm, 24-70/2.8 and a number of shorter premium (portrait, macro, tilt-shift).

    In order to have the "scope" of a 300 mm lens on crop camera, with a device full photo frame, I'd have to lug around a 500 mm. No thanks!

    But in general it is more down to the camera lenses, on what they are used...

    What lenses and cameras I use depends on the type of event, I'm shooting, I can be or want to be mobile, an arena covered, or not, if I don't work out.

    For the dressing, I often have to work in covered arenas. But I'm not mobile at dressage events, so I can implement a 300/2.8 on a tripod to reach the other end of the arena and use a 70-200/2.8 for closer shots. I prefer to stop a bit to a depth of field when I can, but like f2.8 available if necessary to get the shots in the darker areas of the arena. As a general rule, except at a very high level, training cannot and must not be photographed with flash. Most of the horses and riders of dressage junior and amateur is not accustomed to Flash. Dressage is progressing more slowly than some other events, so I can shoot with a slow shutter speed in many cases... 1/250 and 1/320 is sometimes possible.

    Hunter/jumper, stock, gymkhana, and English/Western contests are types of events where I need to be more mobile and tend to use the 300/4 IS and 70-200/4 IS for shooting especially pocket. These types of events are sometimes covered arenas, but are often in locations open, not covered. Even if the scene is covered, it is likely be well lit.  It is possible to use the fill flash, but I try to avoid as much as possible and do not use it too close.

    Hunter/jumper, jumping arena, gymkhana and all kinds of competition stock tend to move around, so I need to use 1/640 or speeds, faster shutter so I want to freeze the action.

    For path testing I try to wear minimal gear because I walk the track with the horses and the riders (not all 6 to 10 miles of most of the formations of TT), but it is completely outdoors in a good light. I use especially 28-135 on a camera and 300/4 IS on the other. I had trouble with the noise of the 5DII in settings quiet test track, but not with the 7 d or even using the 5DII in arenas noiser (I know the 6 d and 5DIII have "calm" modes, but did not use them, what isn't sure how effective they are, or if there are any other questions their use.)

    Cross-country skiing is a type of event where I always struggle to know what to do. If I work close to the House or take a walk outside on the course, I could take more lenses and tripods. But if I'm hiking, I'll opt for the lighter things.

    I sometimes use the 5DII full frame planned, portraits stationary (after the test to see if the horse responds to the sound of the shutter). I also sometimes will use it in particularly dark locations. But usually even those I can find bright spots and those with my 7 d work instead. Then I might be only limited shooting in particular parts of the arena.

    If I could wear only one, it would probably be a device to harvest... on a budget of 60 D-70 D sensor, 7Ds work well for me for more than 4 years and more than 100,000 clicks and will probably get replaced with 7 d Mark II when those who are available. (In the past I have widely used 50 d, 30 d, and 10 d, too.) A unit of harvest gives the most versatility and flexibility, IMO. It offers the "extra scope" which allows the smaller, lighter to, cheaper to serve, as well as all the goals both lenses EF and EF-S can be used (a full frame camera is a bit limited, EF only).

    But, of course, of 6 d low light capabilities could be nice sometimes. It's probably a good two ISO stops rain able your 60 d or my 7Ds... and it's AF is able to concentrate in the lower light about two stops, too (-3 EV, compared to 1 EV). Note that the 6 d is limited to a large extent to the Center AF point only, for any AI Servo/shooting action and low light. (It would be good for me... same thing is true of my 5DII and even with 7Ds and 50Ds, who have much more capable peripheral focus, I still use as the center of a large part of the time.)

    I hope this helps!

  • USB-6009 not recognized after the blue screen of death

    I have two devices USB-6009, used with NOR-DAQmx and Labview to make some analogue simple analogue input and output.  The USB box - two 6009 were previously works very well on this PC.  Recently, I got a blue screen of death, associated with a different USB device to (non - OR) connected to the PC.  I not save the information of the blue screen of death.  When I restarted the computer, the USB-6009 devices were no longer recognized by Labview / MAX.  The Green LED on the USB - 6009 s do not come.  The USB - 6009 s appear in the Device Manager of Windows with a yellow exclamation point ("Windows cannot load the driver for this hardware device").  If I connect the USB-6009 case to another PC, MAX recognizes them on this PC, and I get the usual flashing green LED.  If I connect another USB-6009 (never connected to this PC), I get a green LED solid, and, says Windows cannot load the driver.

    I am running Vista, Labview 8.5 and NOR-DAQmx 8.9.  I rebooted 5 - 6 times, I tried disabling and the reactivation of the USB-6009 by windows Device Manager, I tried the options "update driver" in Device Manager.  Any advice on how else to solve it?  Thank you!

    The driver update and turn do nothing to the main driver - DAQmx. Reinstall or repair that.
