• for control voltage can we use usb-6001?

  where can I find the usb-6001 software and driver?

  You can certainly use a 6001 to control the tension... in line with the specifications of the device.

  Driver belongs to DAQmx, available here: http://www.ni.com/download/ni-daqmx-14.1/4953/en/

• Level of measurement OR-USB-6001 nosie

  I use a NOR-USB-6001 to measure voltages @ 5V level.

  I am trying to use an entry to measure the noise level on a 5V signal. The ripple is about 200 mV ACC (when you look at a scope in coupling AC mode). I can't find a framework in the DAQmx VI to set to measure with a higher resolution (4.9V - 5.1V)

  to be able to see this ripple.

  You could try to configure the line HAVE as a differential input (AI0/AI4).  Power of your signal to AI0 entry and ground of your signal to a DGND.  Feed in the + 5V on the USB-6001 to AI4.

• Simultaneous to the AO and HAVE with the acquisition of data NOR USB 6001/MATLAB Toolbox

  I am very new to data acquisition and bought a NI USB 6001 to start to learn. Because I can get free MATLAB through my University, I use Matlab data acquisition Toolkit as the data acquisition software.

  My problem is that I get the following error message when I try to generate an AO (an LED voltage) signal and measure a signal I (voltage of a battery of 9V) simultaneously.

  ATTENTION: This change is caused in the dump output data queue.  Use queueOutputData for the queue data before the start of the object.
  Hardware does not support the specified connection. Check the user manual of the device for the valid device routes and pinout.

  However to measure IA or by generating the AO each by themselves works perfectly well.

  My Matlab script looks like this:

  daq.getDevices;

  s = DAQ.createSession ('or');

  s.Rate = 1000;

  s.DurationInSeconds = 10;

  addAnalogInputChannel (s, 'Dev1', 'ai0', 'Voltage');

  addAnalogOutputChannel (s, 'Dev1', 'ao0', 'Voltage');

  aoVoltage = 1.8 + 0.1 * sin (linspace (0, 2 * pi, 10000))';

  queueOutputData (s, aoVoltage);

  s

  startBackground (s);

  Note that adding the channels HAVE and AO at the session also works, however I get the error mentioned at the start of the session. This is a limitation of my data acquisition hardware (I don't see something like that mentioned in the manual) or do I have to modify the script?

  The pins connected for the LED are AO0 (+) and AO GND (-).

  The pins connected to the battery are AI0 (+) and (-) AI4. (The problem is still there if I use the reference to the ground for AI)

  6001 cannot make simultaneous tasks.  Very standard limitation of the low-end hardware... just don't have on board computing resources to handle such things.  Even the 621 x boards have only limited multitasking abilities.

  Can intensify to a high range data acquisition ($$$) or buy a 2nd a low end and synchronize tasks in software (not as precise calendar).  I've done two approaches, one is "best" really depends on demand... If low-cost or high-performance is a priority.

• entry digital usb 6001 of nor

  I am trying to simulate a signal digital 72Hz to an external circuit. Attached below is the pattern that I use. I had to initially waveform graph to view the signal, but data types are different, so I ended up using a waveform digital chart vi. Once I run the simulation, nothing in the graph. Help, please. I use a hardware DAQ USB 6001.

  BTW, I tried to create a task in the DAQ Assistant, but succeeds only when the acquisition mode has been set to 1 sample (on request). When you do what I wanted, which was a continuous sampling, an error has occurred.

  Error-200077

  Requested value is not a vaalue supported for this property. The value of the property may be invalid because it is in conflict with another property.

  Property: SampTimingType

  Requested value: sample clock

  Possible values: on request

  Basically, what I want is to see the place in the graph of the signal waveform and perform a signal processing.

  Too bad. I already solved the problem. I used to analog rather than digital input

• take the digital output USB-6001 always high or low in c

  Hi all

  I am new to the NI DAQ interface. I have a USB-6001 and I am trying to use this device to control some flowchart in C. What I want to do is:

  * set digital output lines with high and low intensity and change their status as needed (in C).

  I tested the device NEITHER Max--> Test panels and found that the device is capable to do that. Then I try to do in C. I have checked hace examples and function I use is one called "DAQmxWriteDigitalU32". I have problem in the understanding of its input parameters. I tried something with my own knowledge, but it does not work as I expected. Here is a test I did:

  data uInt32 = 1;

  Int32 wrote;

  TaskHandle taskHandle = 0;

  DAQmxErrChk (DAQmxCreateTask("",&taskHandle));
  DAQmxErrChk (DAQmxCreateDOChan (taskHandle, "Dev1/port0/line7", "", DAQmx_Val_ChanForAllLines));
  DAQmxErrChk (DAQmxStartTask (taskHandle));
  DAQmxErrChk (DAQmxWriteDigitalU32(taskHandle,1,1,10.0,DAQmx_Val_GroupByChannel,&data,&written,));

  taskHandle = 0;
  DAQmxErrChk (DAQmxCreateTask("",&taskHandle));
  DAQmxErrChk (DAQmxCreateDOChan (taskHandle, "Dev1/port0/$line0", "", DAQmx_Val_ChanForAllLines));
  DAQmxErrChk (DAQmxStartTask (taskHandle));
  DAQmxErrChk (DAQmxWriteDigitalU32(taskHandle,1,1,10.0,DAQmx_Val_GroupByChannel,&data,&written,));

  I just want to set ' Dev1/port0/line7' and ' Dev1/port0/$line0"at a high level, but only ' Dev1/port0/$line0' answer me. The second parameter of the DAQmxWriteDigitalU32 function is numSampsPerChan. If I replace (currently 1) with a higher value, such as 100, I see that "Dev1/port0/line7" sends a number of 1 output, then back to 0. So I guess that the problem is just that I understand not all parameters for the DAQmxWriteDigitalU32 function. Is someone can you please tell me how I can set up a line of digital output 1 or 0?

  Thank you!

  Hello

  I finally find a way to do it! The feature works very well, and my problem was not set the data value to write correctly. It seems that if I want to write a 1 to the port0/line1, I put "data = 2 ^ 1" rather than "data = 1", because by default it is the second bit of the port.» Similarly, "data = 2 ^ 7 ' high level to port0/line7. I find that this setting is surprising when you want to control an individual line. It seems more reasonable when you control the whole port. In any case, is to solve the problem!

  Thanks anyway!

• More and more common digital output on USB-6001 with ULN2003A

  I am ordering an engine step by step and the current required on the digital inputs of the stepper driver is close to 11mA (at 5V).  My USB-6001 is not capable of producing this high current.  I've seen people using the ULN2003A to control relay and it looks like it should work for my application.  It will work and then I use the 5V output to go to the ULN2003A because it can produce for a 150mA.  To associate the ULN2003A I use the 5V output and put the positive on the COM?

  As you drew it should be fine. Do not connect data acquisition + 5 V because the controller inputs are opto-isolated. That circuit is also compatible with the 11 current requirement my mentioned in your first post.

  USB-6001 digital lines are software timed so your maximum stage rates will be very high.

• ContGenVoltageWfm_ExtClk-USB-6001

  Hi all

  I just got USB-6001 and tried to go although the demo examples. The question is about the "ContGenVoltageWfm_ExtClk". To after my understanding, there should be no signal AO while no pulse train provided the sample clock source defined (/ PFI0). However, AO signal is always generated as if it is running an internal integrated clock. I use Examples\DotNET4.5.1. Support for USB-6001 external clock example? Any help will be appreciated. Thank you.

  Hello

  The Specification 6001 OR don't mention external trigger. To compare with another product, here's the Specifications NI USB-6211. On page 9, there is an external digital triggersection. for the analog output function, PFI can be used as Trigger Start, relaxing break, sample clock or time Base clock sample.

  This let me think that the external clock for analog output is not supported by NI 6001. Check if for example there are a list of supported hardware.

  Best regards

• What is the first version of labview can be used with a USB-6001

  What is the first version of Labview, which can be used with a USB-6001?

  According to the user's Guide, you must DAQmx 9.9 or later version.  The oldest version of support DAQmx 9.9 is LabVIEW 2010 (DAQmx and LabVIEW version compatibility).

• USB-6001 and LabVIEW 6.1

  I'm working on a project with LabVIEW 6.1.

  They just bought a NI USB-6001.

  I installed the driver NOR-DAQmx 9.9 and the device comes in OR-MAX and I am able to use the Test panels to read and put pins.

  In LabVIEW 6.1, the device does not appear.

  What should I do to be able to program this device with LabVIEW 6.1?

  You need tasks in order to use the DAQmx Read and Write DAQmx.  You can create tasks in MAX or do it programmatically with the available in the palette DAQmx screws.

• USB-6001 and linux

  Hi all

  I have a NI USB-6001 DAQ device that I'm doing work on linux. My distro is opensuse 13.1, and I am using nor-daqmx base 14 to talk to the device. After much bother that I have finally made was get the drivers installed, however I am not having any chance to communicate with the device. The output of dmesg shows that the device is connected and recognized, however the output of lsdaq does not list the device at all as you can see below.
  For the device user's guide suggests that it is supported by NEITHER-DAQmx 9.9 and later it is true that the doc is written from the point of view centered on mswindows, so I
  hope that this applies also for linux.

  If someone managed to get this device working under linux? If not, can anyone think why it is not detected?

  Thanks for any help

• Development of oscilloscope with NI USB 6001

  Hello

  IM planning to develop a virtual oscillpocope with Labwindows/CVI for my University project. I was wondering if its necessary to use the CVI real-time or not? I heavent much experience with CVI and this will be my first project, so if you have any advice that would be great. And also perhaps any similar project developed until I could take a look?

  Thank you

  Cards DAQ have deep pads. Looking just at intervals predefined. Use the callback function timer assync that it is precise to couple of Ms resolution.

• 6001 USB does not accept the inputs for thermocouple

  Now enter one of the differential analog inputs of the 6001 USB a type K thermocouple. I used the wizard DAQ to do, but the shows around 3 oC reading at room temperature. Has anyone else encountered this problem with the 6001 USB? (When I have an input voltage, which works fine, while the device works very well).

  Allan,

  When you run a task of thermocouple on one of our analog input devices the device will read voltage on that channel and then convert it to a temperature using the known relationship of the thermocouple. The Type K thermocouple has a sensitivity of ~ 41 UVC.  The USB-6001 has a resolution of 14 bits with a range from - 10V to + 10V.  This gives us a sensitivity of ~1.2mV or ~29.8 C.  This does not factor in which the USB-6001 has an accuracy of 6 mV absolut which made soar as the other.

  A measure of thermocouple should read changes in voltage very low levels of very low voltage, that is why we have devices speifically read thermocouples.

• Strange analog output of USB-6211

  I just got USB-6211 to replace USB-6001 to set the clock to external sampling on analog output for LED lighting control. The part of external clock example works fine, but the analog output voltage is strange. To do self-monitoring, I connected control pin LED to AO0 & AI0 of surveillance in the NI MAX test panel and LED control on the ground at AO - GND & GND HAVE since I have both USB-6001 and USB-6211, I conducted tests on two of them with the same setting of wire. When I generate sine wave - 5V to 5V to AO0 (from NI MAX test panel), USB-6001 can monitor the same signal AI0, but watch USB-6211 - 3, 4V to 3.4V voltage truncated. I did the test separately (wiring one device at a time), so there is no interference between the two devices. USB-6211 past self-calibration and self-monitoring. Also, I did reset devices. I don't know why they would behave differently with the same configuration, and I hope that someone could help with this question. Thank you.

  Hi skuo1008,

  The USB-6001 can support + / 5 output current my from terminals to analog output, while the USB-6211 box can provide only +/-2 my current output.  It is likely that the load impedance is too low, causing the 6211 to hit its current compliance and thus cut the tension.  If you try to exchange your load with a resistance of at least 5 v/.002A = 2500 Ohms, you should be able to see the full +/-5V sine wave.  I suspect that your DUT has a words 3.4V/.002A = 1700 Ohms impedance.  You could use a device with higher output current or use a more current source buffer circuit.  If you do not need a bipolar output, you might also consider using digital lines to control the LEDs.

  Kind regards
