Can I measure small AC voltage signals with a FP-Ai-100

I would like to measure a 0-5VAC signal in a cFP-AI-100 module,
does anyone know if this is possible?
Thanks
Dusty

According to the specification sheet you should not really see a problem although one other major influencing factor is the 'loop' rate or in other words what else you have going on at the same time.
The maximum sampling rate was quoted at 360Hz but it will also depend on what filters are selected as well.
What frequency is the signal ?
The data sheet can be found here

I recenty ran into a problem when measuring 6 equal voltage signals. When using a g

ood quality digital meter all voltage signals where equal and also using the labview test panel all voltage signals where equal. When measured by my vi i found that the voltage signals where not the same 2 of the channels displayed almost twice the amount.After changing the channel order using the I/O tabs on the right of the control panel I found i got the correct voltage readings. What caused my vi to diplay incorrect voltage readings due to the order of my I/O channels?I am using Labview 6.0 with a SCB-68 shielded I/O Connector Block interfaced with a NI-DAQ Multifunction I/O board PCI-MIO-16E-4.

I couldn't open the attachment you posted. However, you probably set the wrong input limits for your gains or had a too small interchannel delay in between channels that wasn't letting the instrumentaion amplifier to settle down properly.
A good way to make sure your VI is the cause for the problem is to run one of the Labview shipping examples to do the acquisition. The best one to try is the one named Continuous Acquisition and Chart(buffered).vi.

Aquisition of a voltage Signal with PXI 6713

Hi.
I want to make voltage aquisition with a PXI 6713 card. I take the Channels ai16 to ai33. The voltage at the clamp is 3.886VDC ( measured with a DMM ). When i measure the voltage and calculate it into a current ( see my applikation atteched ) the result is something between -10 and -24mA?!?!?
Are the settinges in the DAQmx Express-VI "analog voltage aquire" wrong or could it be another Problem?
My settings are:
RSE
voltage measuring from 0 to +8VDC
N Samples
I hope of yous Answer.
Thanks

Is it a trick question??
First of all, Looks like you mentioned the card wrong PXI 6713 is an AO card, without any AI channels
Which card are you using??
Are you connecting a 390 ohm Resistance on your connector block to convert current signal to Voltage equivalent?? ( Sounds like you are not )
Are you measuring the Voltage correctly in the first place??
if you are not, check if the signal is connected correctly for RSE mode
Hope this Helps

How to continously generate a voltage signal with dynamic amplitude.

Hello all,
I am looking for ideas and pointers (help in other words). I would like to generate a voltage signal (sine for example) on a AO of my NI cRIO-9263 (DAQmx). The signal should be:
continuous (without jumps ie. smooth)
dynamically able to be change the amplitude, frequency and sampling rate.
interuptable so that the AO can be turned off.
I have tried to use the DAQ Assistant but once it runs in continous mode, I have the impression that the waveform should not be changed. Is there maybe a way where I send repeatedly N samples of the waveform to the AO and gain more control over the signal that way. But if I do that how can I ensure that the signal is continous?
Further more this output has to be generated in an event application ie. in the background.
Your ideas and input is appreciated. Thanks, Bernie

Can I extend my Sky wireless signal with an AirPort Express?

Hi,
I recently got an AirPort Express in the hope that I would be able to extend my wireless signal to areas that currently have a weak and unreliable signal from my Sky SR101 router. I am currently able to do this with an old Belkin 'Wireless G Universal Range Extender' but it is not ideal - it's quite temperamental, it has to be reset from time to time and it also provides pretty low speeds. I've tried configuring the basics for the AirPort Express but can't seem to get it to work. I've seen on the forums that some people think it is impossible to extend a non-Apple base station's signal with an AirPort Express while others have managed to get it to work. I would suspect that if I am able to do it with an outdated Belkin range extender I should be able to with a brand new AirPort Express - I don't know!
Very grateful for any thoughts/comments/solutions.
Thanks for reading.

Perhaps have one connected to the Sky router with an Ethernet cable and then boost the signal from that one with the other? Would that work?
If the 1st Gen AirPort Express really is a 1st Gen, then yes, you could do this.
Check on the side of the AirPort Express for the model number.....hard to see in the faint print.....so you may need a magnifying glass.
A 1st Gen AirPort Express is model number A1264.

Can not measure temperature and voltage simultaneously

I am a beginner with labview. I want to measre temperature and voltage simultaneously. When I run
the VI, I can get temperature or voltage, but not togther. I attach my VI, please give me suggestion on
how to make it work. 3X

Since I don't know your exact configuration I will make some basic assumptions based on how it appears that you have configured the DAQ Assistant Express VIs.
Assumptions:
1. You have only one DAQ board in your system.
2. You want to scan continously
3. You want to acquire 3 temperature channels at a rate of 1000S/s and take 100 readings at a time
4. You want to acquire 2 voltage channels at a rate of 1000S/s and take 1000 readings at a time.
Based on this configuration your first problem is that you have configured the DAQ board to acquire continously in the first call to the DAQ Assistant (your first frame of the sequence structure). This ties up all the analog acquisition resources without releasing them. When you make your second call to the DAQ Assistant (your second frame of the sequence structure) you are creating a conflict because the DAQ board is already busy running your first request. At this point you are probably receiving an error but you might not see this since you are not doing error checking in your code. This is also why you are only getting one set of data. Next iteration of the while loop the first call to the DAQ Assistance reconfigures the board and executes again and so the cycle repeats itself.
I don't have a DAQ board installed so I can't confirm with certainty if I am correct but you can do this by simply changing the DAQ Assistant properties. In the 'Task Timing' tab change from 'Acquire Continuosly' to 'Acquire N Samples'.
Assuming this works all you have done is confirmed that my assumptions are correct and technically your program should work. So now some programming advice.
It's ok to scan all channels at once even though they might not be of the same type so go ahead and configure all your channels in one DAQ Assistant call and get rid of the sequence structure. Decide on one set of parameters for Scan Rate and Samples to Read, in your case I doubt this will be a problem. Since you are performing the same analysis on all channels you don't need to parse your data simply pass the 'data' from your DAQ Assistant into a single 'Amplitude and Level Measurements' Express VI. You will now have a single array with all your Mean values based on the order the channels are configured. If you want to plot the data in different graphs all you need to do is parse your channels using the 'Split Signals' or 'Select Signals' Express VI.
Hope this makes some sense.

Can I measure full bridge gage configurations with SCXI1121 and 1321 terminal

Hello
I designed a load cell that uses a full bridge gage configuration. I have at my lab a SCXI 1121 module with a SCXI 1321 terminal block. I need to know if it is possible to use that hardware configuration in order to make de load cell and the data acquisition system fully functional.
Thank you.
Best regards from Bogotá, Colombia, South America

Juan,
The full brige configuration you are speaking of requires four wires, two for voltage and two for excitation, is this correct? If so here is a link that you might find helpful.
Full Bridge Configuration
This reference is for strain gauges, but the connection for a full bridge is going to be the same. The channel plus and minus and excitation plus and minus can be connected to the 1321 for the individual channel. To configure the proper gain, filtering, and excitation mode and level, please refer to the Getting Started with SCXI on pages 3-14 through 3-23 (pages 51-60 in the .pdf).

Can I use my iPhones 3G signal with my iPad?

Before I bought my ipad2 with wifi, I had an idea I could use it using my 3G signal from my iPhone. If I can how? I've searched on the help pages with no luck, so maybe it doesn't exist?

How can I measure coherence between EEG signals using labview?

well, I have an EEG signal(a matrix 16X8498)whose lines represent the channels and collums the samples. The last line is the stimulus channel. I would like to know if I can measure the coherence between my EEG channels(lines)using labview.If,yes,is there someone who has the block diagram?

Search the Labview help for coherence and you'll find several functions (in Labview 6.1 Full Development System). The functions are in the palette Analyze >> Waveform Measurements >> Frequency Response Function (Mag-Phase) or (Real-Im).

I have an SCXI-1531,1126,1120D (with 1327) connected to PCI-6052E. How can I measure an ICP force sensor with some/all of this?

As I understand it, I may only need to use the 1531. Although it says it is used for accelerometers, it sounds like the techincal specifications of the card are adequate. I will be measuring in the range of 30 Hz with force sensors. The sensors are made by PCB Piezoelectronics, model 201B02. This equipment was somewhat inhereted, so I don't really know what of it I must use, or how. Any guidance would be appreciated.

Dave,
It appears that your force sensor is compatible with the SCXI-1531. This module supports all Integrated Electronic Piezoelectric (IEPE) sensors. Thus, it is not limited to accelerometers. I examined the data sheet for your sensor, and it indicates that a Constant Current Excitation of 2 to 20 mA is required. The SCXI-1531 provides a constant current excitation of 4 mA. In the same way, it appears that the other specifications of your sensor are compatible with the SCXI-1531.
Good luck with your application.

Can't Train Reader X to open with Maximized Window at 100% zoom

I thought there was an option for this under preferences for previous versions. Or maybe the previous versions were smart enough to just remember if you had it maximized the last time you opened it.....like pretty much every other Windows based program.

Sorry - I thought that was what you wanted. Under the same menu, go to the "Documents" category and make sure "Restore last view settings when reopening documents" is checked. It seems to work for me... once selected I maximized my document, closed it, then opened that and other PDFs with Reader and they opened maximized.

How can I measure the frequency of an analog signal?

Hi, I am trying to measure the frequency of VAC signal coming from a gas turbine engine at my university. If I can get the values of frequency, I can determine the speed (RPM) of the engine. I am fairly new to LabVIEW and I have been looking through manuals like crazy in order to find out how to obtain the frequency. I have measured the signal with an oscilliscope and the highest frequecy will be about 1.5kHz. I am currently using a USB-6218 and it can collect the voltage signal with ease, but it won't give be analog frequency so simply. Can anyone explain a way for me to obtain the frequency values? And if you could show or tell me in a very simple way (because I am not very fluent in LabVIEW yet), that would be amazing! Thanks!

How can I use Labview to create a graph of digital voltage signal vs. Time?

I am measuring a digital voltage signal and I need to generate a graph vs. Time and be able to add user controls to start/stop the graphing and be able to export the graph to other programs such as MS Excel. Any help you could give would be much appreciated. Thank you.

You probably want to use a chart. Place it inside a while loop that runs continuously. The chart should be in a case structure so it is bypassed depending on the boolean pause/continue switch.
To save the data, get the "history data" of the chart via a propery node and save it to a file. It is probably easiest to save it to an ASCII file. Most other programs will be able to read it.
See how far you get. If you get stuck, post your VI and we'll help you.

How can i measure a voltage with the digital i/o port on my nudrive using labview?

I am using a 4SX-411 nu drive to control my stepper motor. I need to measure an input voltage at the digital I/O port of the nudrive. How can I program LabVIEW to do that?
Thanks

Hello Raven24,
Thank you for contacting National Instruments. NUDrive 4SX-411 is a value motion drive and you can connect to it using any of the ValueMotion boards. When using a ValueMotion NUDrive with steppers you have I/O ports 1-4 available for general purpose use, I/O ports 5-8 are reserved for axis inhibit output signals. Refer to section 4-7 of the ValueMotion Hardware User Manual linked below, for information about the jumper settings.
ValueMotion Hardware User Manual:
http://digital.ni.com/manuals.nsf/websearch/6CF7A54E0BDEA1388625665F0054FFDF?OpenDocument&node=132090_US
Once you have setup the jumpers appropriately, you can use the VIs found on the ValueMotion I/O & Limits pallet for configuring and using the I/O channels. Search for "I/O" in the attached help file for more information about these VIs. I hope this helps you out. Have a great day!

How to measure a current signal with NI 6211?

How to measure a current signal with NI 6211?

Hi Clecio,
This is a charge accelerometer. It is different from the IEPE accelerometers that outputs a voltage signal.
You need a charge amplifier. Then according to the charge amplifier output we can select an appropriate module to measure the signal.
It is not possible to measure charge accelerometers with NI 9234 directly.
