PCI-6110 to change analog input range
The analog signal I want to measure is 24 volts and the maximum PCI 6110 is Volt.However 42, analog inputs that appear in the device under device NOR-DAQ traditional (old) configuration is 10 volts (single selection). I'm using LabView 7.1, DAQmx 8.6 and there is no function for allowed me to modify and change the analog device input range (Please find the print screen of the attachment). Can I know how can I change the analog inputs range?
I think that's what you're looking for:
You must set up an appropriate gain so that the other ranges of voltage is displayed.
In addition, you can post on the forum instead of Labview data acquisition in the future, because the chances are that you will get better/faster responses there

I have a PCIe-6343 and I want to be able to power different ranges on different channels of entry at the same time, more precisely with the customer is able to select ranges for each channel when necessary. Ideally I want to I could have HERE with-10 0 - 10, AI 1 to 04:55, AI 2 with-1 to 1 and AI 3 with - to 0.250 0.250. Anyone know if this is possible? I tried to put a table for the minimum and maximum values, and it did not work.
The only active channels are the ones you decide to put in the array. The only beaches that are enabled are the ones you decide to place in their bays. How you decide to complete the paintings belongs to you. I suggest a front screen where you are able to select one channel and the beach, then click to add to a list.
I'm starting my first app using a card of RIO for the analog input and power (two PCI-7833).
My previous experience with DAQ systems was on PC so I'm especially familiar with DAQmx. It is my understanding that DAQmx is not really being used on these boards, there is no DAQmx tasks to play with.
So, my question is this: How can I dynamically set the range of the signal of the analog inputs so that I get the best possible resolution?
What I want to say in DAQmx if I know that the input signal is only 1 V pk to pk I can put this beforehand in the task.
OK, a little further digging shows the input range is set to +/-10V, is this correct?
I am currently working with the NI USB-6218 acquisition card.
In order to acquire a signal, I would like to be able to choose the input range of the DAQ with a digital command Wizard (and not opening the window of DAQ assistant) (as 'number of sample' and section 'rate'...)
Is this possible and if so, how?
Thank you very much in advance for your answers!
You can't with the DAQ Assistant so just click on and select "generate the Code of OR-DAQmx. You can edit the Subvi who performs the installation.
I have a difficulty connect an analog source to the analog inputs of my acquisition of data (USB-6215). The analog signal is output operational amplifier through a 10 k resistor. I wore the signal out of the amplifiers is 10V peak, I then move the probe across the 10 k (the analog input terminal) and the signal is clipped to +/-0 .5V. If I reduce the amplitude of the signals of source less than 0, 5V Ridge there is no clipping.
Maybe the analog input range the value +/-0 .5V which is causing this as a form of protection? I don't have a LabView to try to change the input range as I do just the wiring.
Analog source is connected to him HAVE 0 and the ground of the analog source is connected to the GND AI.
Thanks in advance.
Have you tried to read the data through the data acquisition device? If that's what you try to do, I'm curious about what we read.
If you have measurement and Automation Explorer, go ahead and open a Panel to test for the unit and see what are your tensions.
Let us know how it goes.
Hello. I m using a PCI-6013 OR DAQmx 9.1.1 with Labview 8.2 (sued) WinXP. The jury has undergone an immersion in water during a flood but was cleaned, recognized by WinXP and NIDAQmx.
I have run the Measurement & Automation explore and use the test under option OR-6013 'Dev1' panels 'devices and Interfaces. Here, I can see that the digital and clock output work perfectly (I can change the State of the digital channels and duty cycle and frequency of the clock). The problem arises when you try to measure an analog voltage. I tried on several cases not all analog channels using NRSE and differential modes (switch accordingly connections).
The signal comes from a (4 Hz, squares and sines, 5Vpp) signal generator via a CB-68LPR connector.
I only see something comparable to the entrance of singal when you use differential inputs (signal connected by J57 and J23) AI7, but the signal I see comes with 100 mVpp instead of 5 Vpp (I can see changes in the shape, every time that I have spend of a sine, square, ramp...). I also tried connecting J23 AISENSE (J62) and AIGND (J67), to avoid the problems of floating source. The same thing happens when enter and set up the acquisition by the vicinity of data in the Explorer of Measurement & Automation. I m using the reach of the signal in the different ranges, tried with 04:55, -1 to + 1, 09:50... When you configure tasks NIDAQmx I choose to read different samples (100, 1000, 10000) rate (100 Hz, 1 kHz,...) and combinations. Anyway, the input signal is always 4 Hz. I checked the signal with an osciloscope and I see it perfectly.
Is it possible to have the broken while the digital and general-purpose analog input clock outputs are OK? Y at - it a tip for the connections I should know about? Thanks in advance for any guidance!
Thank you both, KateB and MarisolM for your answers.
I made several the tests con señales DC y con señales senoidales, instalando placa en back different computers, y no obtengo resultados positivos, is spite of what el self-test selling well. Seems that the Plaça realmente esta fallando.
I did several tests with DC signals and senoidal, installing the card in two different computers, without positive results, even if the self-test is OK. It seems that the Council really works hard.

I'm reading an analogue signal which varies from 0-11 V using a card of acquisition data PCI-6111. The signal comes from a Tube set (PMT) which is part of a microscope configuration, so it is very important that the resolution of the analog input signal be as wide as possible generate quality images. According to the data sheet for the PCI-6111, the analog input resolution is 12 bits, which should correspond to a sensitivity of ~2.686 mV for my voltage range.
To test this, I set up a task to analog input with a 0-11 V voltage range to read samples of an analog output, which I wrote a simple waveform. Since the 16-bit analog output resolution that I assumed that it would not limit the accuracy of this measurement. I have attached the VI I used for this measurement below. The analog input data are saved not truncated in a text file.
Analyzing these data, I found that the real input sensitivity is ~9.766 mV, corresponding to levels of voltage exactly 1126,4 and ~ 10 bits.
Is there a reason why the resolution of analog input is much lower that it is indicated on the card? What are some of the ways I could improve the sensitivity of this measure?
Sorry, when you mentioned the specs, I thought you already had them. If this did not come with your Board of Directors?
I use an analog input on a PCI-6224 and are having problems with the clock source. I'm trying samples of 16 different analog inputs very quickly. I have the sample mode: Timed Single Point material. The rate, that I am running is the maximum (250 kHz (15625Hz per channel)). I left the default clock source and trying to taste several times. The analogue input works for a short time (2-3 seconds) and then everything stops. I'm doing something wrong or is there something I'm missing? Any advice would be great.
That's how you samples using the sample clock clock. If you see a delay then something is wrong with how you track/data visualization.
Single point NI the hardware is for PID control with a real-time operating system.
I inherited a program extremely complex. I find that I see 15-20 seconds latency on the changes to the analog inputs. I can't post the code - (it has more than 200 sub screw) but I have captured the relevant section in the long latency period of the changes.jpg of analog input attached.
I tried to change the sampling rate and see the same problem from 1 Hz to 25 Hz (limit of reliable sampling with this PC). I'm looking at indicators which are directly related to the acquisition of data Read.vi as evidenced by the big red arrow.
I modeled the nested struct in the template attached without latency problems.jpg. There is no perceptible latency but it duplicates the nested structures.
The only thing not shown is that there are several cases of Read.vi of data acquisition using the same physical changes but not of them are in the loops that need to run at the same time.
The data are consistent with the entries, just delayed.
The Signal processing device is a USB-6343. I am running these screws on LabVIEW 2011 edition.
Yes, instead of getting just 1 sample buffer, try to get all the samples.
Then you can retrieve the most recent example of all the samples you get and take the rest of them.
Or you can change the configuration of taks for only once every time that you call the read function.
I have problems to install a PCI-6132 card on one of my computers. I am runing Labview 7.1 and DAQmx 8.6. In MAX, I opened the unit and test panels. The counters are working fine however the analog inputs always give v - 10 (-5 If the a - 5 min) without noise. the same on each channel. I have not connected any termianls and expect to see the noise around zero volts. In addition, the card fails the error calibration auto-200545.
I took an another PCI-6132 of a system works in this computer and had the same problem. So I guess the problem is the configuration of the computer or software. I try to reinstall the DAQmx and labview and the problem has not been corrected.
I'm trying to synchronize the clocks of reference of 2 PCI cards so that the analog inputs are synchronized. However, my appilcation has also digtial e/s on two cards, and who apparently made the mistake DAQmxErrorResourcesInUseForRoute_Routing. This discussion describes a similar problem, but the solution was to just put the reference clock to the slave device, who had no other tasks running on it, so what mine does.
Is there way I can synchronize the clocks of refernce without interfering with the digital I/o?
PS: My application is in C++.
The reference clock is really a lower-level component that is shared by all resources on a given device. All tasks on a given device must use the same reference clock. So if you use DAQmxSetRefClkSrc for a task, you can use it to set the same value for your other tasks.
Can I set the analog inputs of the PCI-6251 in configuration of mix (some in differential mode) and others in single ended mode. Because in my set up the differential option is grayed out.
Yes, you should be able to do. You have 16 analog inputs. Differential, you will use two of them per channel. See the manual of series DAQ M. you can program channels on a M Series device to acquire with different
reference to the ground. To allow m
ultimode sweep in LabVIEW, use OR-DAQmx create
Virtual channel.VI of the API OR-DAQmx. You must use a new VI for
each channel or group of channels configured in another mode of entry.
Don't forget that for a premium that you would for example wire HAVE 0 to the + side and AI 8 - side. So now you can not use the AI 8 for simple nerve. HAVE 1 corresponds to the AI 9 etc. until 7 AM, GOT 16.
I hope this helps.
I'm reading the analog input of a PCI-6111, who receives a square signal of 1 KHz with a cycle of 50%. I put the sampling frequency to 1 MHz and wait until the data points are 1 usec outside. When I check the signals received, it appears that the duration of each period of the square wave is 1.22ms instead of the expected 1.0 ms.
The following is a snippet of what I tried:
int NUM_SAMP = 10000;
Can you tell me what I am doing wrong?
A good place to watch code you know works would be the finder of the example. "" "" Open the finder example and navigate to hardware input & output "DAQmx" analog measures ' tension ' ContAcq - IntClk.prj
Run this code and see if you get the same results. If so, then we would know that it's a hardware problem and not a problem with the programming. If you see the correct behavior, then you have code that you can shape your out of. I hope this helps.
I am trying to determine the effect of a 12 K resistor that is in series with an analog input of an NI PCI-6229 data acquisition card. Resistance of 12K seems to be part of a RC filter. I have a 0-10 VDC source this supply circuit. What is the impedance of the analog input of the NI PCI-6229 data acquisition card? If it makes any difference, the analog input is connected in differential mode with a 180K resistor to Gnd AI.
The input impedance is classified in the specifications 10 GOhm. So, the effect of your k 12 resistance should be relatively low. Take care!
I found the list of different skin options on the [ADF Rich Client Demo site | http://jdevadf.oracle.com/adf-richclient-demo/faces/components/skinningKeys/inputRangeSlider.jspx], but I couldn't not (explicitly) an option to specify the height.
I tried to add the height to af. inputRangeSlider::content however which only affects the size of the bounding box of the element. Are there other count options that might not be on this list? Or is it just not possible?
