Is the USB-6008 controllable by Mathcad?

Can I use Mathcad calculation power to manipolate analog data converted
by a USB-6008 interface?
If yes, please indicate examples sources (if any).
Thanks .

Hi nonnog,
I don't understand very well what you want to do, but you have 3 possibilities:
if you have Labview you can acquire data from NI device and then you can use MathCad via ActiveX with Labview with the specific libraries downloadable at link: http://venus.ni.com/stage/we/niepd_web_display.DISPLAY_EPD4?p_answer=&p_guid=B799BC00B8835510E034080...
if you haven't Labview, you can acquire and save data from NI-USB device with 2 NI software ("VI Logger Lite" or "NI Data Logger" provided at no charge with driver) and then you can read these files from MathCad
if MathCad provides the possibility to create Macro or to call dll you can directly use driver functions to acquire data from the NI-USB device.
I hope this helps you.

The analog outputs of the USB-6008 are only rated at 5 Milliamps per
channel. One suggestion for getting it to work is to use an emitter
follower to get more current to drive your motor.

Input Capacitance of the USB 6008

Does anybody know the input capacitance of the NI USB 6008? Im creating a circuit that mimics a 10x probe whose design requires the value of the "oscilloscope" input capacitance, or in this case, the USB 6008 input capacitance.
Thanks so much!

With the low input resistance (144 kohms) the capacitance does not matter much. Any realistic value of input capacitance will have a time constant shorter than is meaningful for the device bandwidth.
Also note that the input impedance is terminated in about 1.4 V. See the circuit in Figure 7 of the User Manual.

Measure like the testpanel of the USB-6008

Hello,
I want to measure like the testpanel of the USB-6008. What is the right
example of the nidaq installation or what are the necessary c-functions?
The most c-examples quits with an error. So I don`t no what is the right. I searched in the dictionary "Analog In".
Thx Pellaeon

Hello,
you can find all examples for DAQ in C:\Programme\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\Analog In\Measure Voltage.
Do not forget adding the include file and the library file to your project. That is described under NI-DAQmx C Reference Help. You can find this under Start->Programs->National Instruments->NI-DAQ-> NI-DAQmx C Reference Help and there under Getting Started--> ANSI C
USB-6008 is supported in NI-DAQmx 7.5 or NI-DAQmx Base. http://digital.ni.com/public.nsf/websearch/4D915A820A76823C862570390075EBF5?OpenDocument

Seperate channels from the usb 6008

I am trying to read EMG signals into labview by using an USB-6008. At the moment I have tvo electrodes, and I have successfully managed to get both signals into labview. The problem now is that I want to seperate the signals. I want my program to listen for both signals, determine which electrode is active and perform specific tasks depending on the different signal.
Im sorry if this sounds confusing, I'm confused by it too.

Hi!
I may be wrong but you can create two separate tasks.
The limit is that they cannot run at the same time.
Depending on the application, the use of two tasks or a single "acquire all" approach can be the best option.

Marco

Download just the USB-6008 driver (DAQmx) ?

Hi
Is there a way to download only the driver for my USB-6008 application
? Which means that I don't have to downlaod the installer with MAX and
support for different programming enviroments ?
Regards
Daniel

Hello Daniel,
When you install NI-DAQ, you are given the option to include support for multiple software programming environments, and MAX as well. You do need to install MAX and support for the API that you will be using, like LabVIEW 7.1 for example, but you can choose not to install support for everything else, like LabVIEW 7.0, CVI/LabWindows, .NET, etc.

Will USB-6008 DAQ be able to power and record voltage for UMS T5 tensiometer at the same time?

I would like to use my NI USB-6008 to provide power to my UMS T5 tensiometer (http://www.ums-muc.de/en/products/tensiometer/t5.html) as well as take readings from it, but I don't know if this is possible to do properly. The supply voltage for the instrument can be as low as 5V, which I can easily get from the dedicated +5V channel. I am able to power the instrument and connect it to an analog input on the 6008 and measure a voltage in differential mode. However, while reading the support literature for the instrument, I find the following:
"Potential data acquisition pitfalls: Because the pressure transducer is configured in a Wheatstone full bridge, the input voltage and signal mV output cannot be connected to the same reference (ground). Hence, the signal mV output can only be measured using a differential voltage measurement. Therefore, do not attempt to make a single-ended measurement of the pressure transducer mV output." (http://www.decagon.com/assets/Uploads/MeasuringUMSTensiometerswithnon-UMSControlandDataAcquisitionSystems.pdf)
My understanding is that the 6008 can take a differential measurement if I attach the signal "+" and signal "-" to the positive and negative analog input terminals. However, it seems that all of the Ground ports on the 6008 are grounded to the same reference, which would make my voltage measurement invalid according to the paragraph above. So my real questions is: if I attempt to record the voltage using one of the analog inputs on the 6008 in this way, is the measurement valid? Or do I need to find a separate power supply with a different reference ground to ensure that the measurement is accurate?

The specification sheet for that device is very poor. The manual is not much better. Companies which want to sell scientific equipment should publish decent data sheets or get out of business.
In section 3.4.3 General requirements the device is described as a "non-amplified bridge circuit." This information along with the bridge impedance should be in the specifications because it is essential to applying the device under any circumstances other than the nominal behavior at 10.6 V.
The answer to your question is this:
You can use it with the USB-6008. The 5 V power supply will result in output voltages slightly less than half (5/10.6) the voltages specified under nominal conditions. You can use the differential input mode on the USB-6008. The absolute input voltages will be about 2.5 V with the 5 V supply. That voltage is within the working range of the device. The differences will probably be less than 100 mV. The resolution of the USB-6008 on the +/-1 V range is about 0.5 mV so your pressure resolution will be around 1 % of full scale. The input impedance and termination voltage of the USB-6008 will introduce some errors. These may be on the order of 5-10%. I cannot predict much better without the missing bridge impedance specification. Those errors should be systematic and relatively constant. A calibration of the whole system - sensor and DAQ device together should allow you to compensate for much of that error.

USB MIDI CONTROLLER- LOGIC PRO 7- I CAN SEE THE LIGHTS BUT NO SOUND OUT?

I just got logic pro 7.2 so i am very green, garage band automatically recognizes the usb midi controller and i can hear it,
in logic it recognizes it i can see the lights for sound levels but no sound is coming out, ive been trying to figure this out.

Heck, if loneliness is your thing... more power to ya!
now why cant i hear the midi
MIDI doesn't make a sound. You either need to assign a software instument to it or use an external device, all depending on the track you chose. If you, perhaps elaborate a little more as to what you did (typing with your caps lock released), there's a better chance of getting your problem solved. If you're hearing your recorded guitar, then there's a chance you selected the wrong type of track to record to as far as MIDI tracks go (there is a difference in Logic).

Simulated device capability for the NI USB-6008

I noticed that Nidaq 8.3, does not have simulated device
capability for the NI USB-6008. Is there any way of simulating
this device?
Thanks

Hello mmac,
Unfortunately, there is no way to simulate the USB-6008. If you would like to see this functionality in a future revision of NI-DAQmx, I would encourage you to go to the Product Suggestion Center and submit a product suggestion. R&D considers these suggestions when deciding on new features for development.
Best regards,

Per-channel gain on USB-6008/6009?

Is analog gain controllable on a per-channel basis on the USB-6008/6009
DAQs? In other words, could AI0 be set to an input range of +/- 10V
while AI1 is set to +/- 1V?

Yes! You sure can set the range on a per-channel basis.

Error -10401 occurred at AI Group Config - in relation to USB-6008

I'm attempting to run a simple vi that uses AI Aquire Waveforms.vi to input voltage data that I have coming in from the USB-6008 DAQ. However, when I try running the program, I receive the error:
Error -10401 occurred at AI Group Config
Possible reason(s):
NI-DAQ LV: The specified device is not a National Instruments product, the driver does not support the device (for example, the driver was released before the device was supported), or the device has not been configured using the Measurement & Automation Explorer.
And I'm not sure how to fix it. In MAX, the device seems to be working properly and everyhting seems to work fine in the test panel, so I'm slightly at a loss. I'm running Labview 7.1, and installed NI-DAQmx 7.5 which came with the USB-6008.

Never mind. I'm new to Labview, and didn't realize that I could not use the traditonal Data Aquisition components with the USB-5008 (I didn't even realize that NI-Daqmx was different).

NI-DAQmx 8.3.0f0 installed but Found New Hardware Wizard shows up when plugging in a USB-6008

I have NI-DAQmx Device Driver 8.3.0f0 installed with LabVIEW 8.2 but when I plug in a NI USB-6008 I see the "Found New Hardware Wizard" in Windows XP. Since the DAQmx driver is installed shouldn't Windows recognize the device immediately?
I cancel the driver and I get the taskbar message "A problem occurred during hardware installation. Your device may not work properly."
The USB-6008 does not appear under Devices and Interfaces in MAX.
Help would be appreciated.
Thanks,
Dave

Ahh, I thought Windows performed an automatic search after cancel is clicked.
I clicked next and allowed Windows to search and it says:
"Cannot Start this Hardware"
There was a problem installing this hardware: USB-6008
The device cannot start. (Code 10)
I tried uninstalling and reinstalling the device but the results were the same.
Any ideas?

USB Host Controller not recognized by Windows 7.

Just installed Windows 7 in a1130n desktop. The USB Host Controller and the Std USB Host Controller are not recognized by the operating system. The USB ports and the media memory ports on the front panel will not work.

My HP Z400 is suffering from the same problem. Did you discover a solution?

Using USB-6008 on LIS331 Accelerometer

Hi, I am looking to monitor my project with a LIS331 using the USB-6008 dac. Would this dac unit be acceptable with this accelerometer?

swong46,
I would recommend using a USB 63xx series DAQ device. You might also be interested in the USB 8452, which is a dedicated I2C and SPI device.
I can also put you in touch with some of our sales engineers, who would be the most knowledable about your options. Shoot me a PM if you're interested, and I can give you a number to call.

Using USB-6008 software timimg Generate waveform

I am using USB-6008 device. Base on it's User Guide, this device on support software-timed and maximum update rate is 150 Hz.
By place a time delay VI for 1ms, I have a 1.660Hz sine signal. Is this wrong for place a time delay VI for software timing?
I would like to generate a 60 Hz signal by using software-timed VI on USB-6008 device. How should I do?
Thanks a lot.

DephinTW,
The update speed of the USB-6008 is largely dependent on the speed of
you computer as well as anything else on your USB bus. If you are using
an older computer or have other USB devices on the bus, you may not
achieve this rate. In order to output a 60Hz signal, the minimum output
sampling rate is 120Hz. This corresponds to an 8.3 msec. delay between
samples. Instead of using the "Wait" VI, you should try using the "Wait
Until Next ms Multiple" VI. Place this in parallel with your
generation. This will synchronize the output with multiples of the PC
clock, rather than waiting for a fixed amount of time, irrespective of
code and USB overhead.
Hope this helps,
