DAQ with ADC - analog to digital

I have a customer who needs to Analog to Digital functionality on a PC card. Do you have such a card and is it compatable with HTBasic. The user has many tests written in Rocky Mountain Basic which he would like to port to HTBasic for windows. I know that we have have a daqni.dw6 driver that will allow HTBasic to interface NI DAQ soffware, and hence control the card. What model of your cards can do A to D and do you think it is likely that HTBaisc which can control other DAQ cards from NI could control this card?
Thanks!!!

Hi,
Pretty much all major National Instruments hardware has at least one analog to digital converter. I recommend taking a look at M series boards for most DAQ applications. I would like to point out that these boards use the newer DAQmx driver instead of the Traditional NI-DAQ (Legacy) driver, so you may want to look further into the daqni.dw6 driver to see what it can interface with.
HTBasic is not a supported ADE. Therefore, I cannot guarantee that the hardware will work on that environment.

I need help with the analog to digital VI

hi there
i'm trying to create some sort of 13 bit virtual adc
what i want to do is to use a simulated signal ( e.g. sine, squared, etc.) sample it at a frecuency rate of 8 khz and send each digital sample by de serial port.
the thing is that i don't really know how to use the analog to digital VI, I know it converts an analog signal into a digital waveform or table but i want to be able to use that digital data and not just watch it on a table
sorry for my bad english and thanks in advance
Solved!
Go to Solution.

well i disigned a digital telphone switch (PABX) on a fpga and y want to test it with labviews signals so i dont have to buy expencive ICs (adcs and stuff)
my idea is to use labview to simulate analog signals and sample them to send that digital information to my PABX and once its been switched send it back to lab view and display the switched information on a waveformchart or something.
hope you get my idea i just dont know how to xplain
there's the VI i made to try to understand how the analog to digital VI works
thanks for your help

Audio problems with Canopus analog to digital converter

I'm trying to digitize and import VHS tapes into iMovie 08. I'm using the Canopus 110 analog to digital device. I've connected the VHS player to the Canopus with RCA cables, as prescribed. The video has imported beautifully — but there's no sound, and so my then 2 year old daughter appears to sing, but alas, no voice — except, for the occasional clip (about 2 to 4 seconds of sound on a 30 minute tape). Any ideas? (I've spoken with an Apple tech who walked me through a test before assuring me the problem didn't seem to be with iMovie ['-).

Hi
a. You did install the Canopus programs (on CD) ?
b. I connect mine to a Standard VHS-VCR and use the SCART connector on it's back
and to this a RCA to SCART plug WITH AN IN AND OUT Switch !
On my VHS-VCR there are two SCARTs on it's back - only one of them works for this.
c. If You in iMovie pref - set Playback via Camera - picture will play but sound
will be directed to analog device = Your Canopus
and if You connect a TV to this or via the VCR (as I've done) the audio playbacks
nicely trough this.
Sorry this only goes for iMovie 1 to 6 - not for 08 or 09 (very bad)

Start by looking around the examples that ship with LabVIEW (if you are
using LabVIEW).
Also look around zone.ni.com for general data acquisition information &
examples. A good site.

Simultaneous analog and digital waveform read with PXIe-6361 and BNC2120 ?

Hi there,
I am trying to collect both analog and digital signals from a PXIe-6361 linked to a BNC2120, using the attached VI. I am running Labview 2011 64bit. This is the first time I am working with digital input. On the 2120 board, I have the digital input BNC cable connected to User Input 1 and wire between the screw terminal of UserInput 1 and the P0.1 (Digtial I/O) screw terminal.
I have two questions related to this:
1) When I try to run the VI in its current state, I get the following error:
Error -89137 occurred at DAQmx Start Task.vi:3
Possible reason(s): Specified route cannot be satisfied, because it requires resources that are currently in use by another route.
Property: RefClk.Src
Source Device: PXI1Slot2
Source Terminal: PXIe_Clk100
Required Resources in Use by
Task Name: _unnamedTask<6>
Source Device: PXI1Slot2
Source Terminal: None
Destination Device: PXI1Slot2
Destination Terminal: RefClockInternal
Can anyone point me in the right direction for troubleshooting this?
2) I would like to combine my regular waveforms and the digital waveform into one array which would then be written to file. I can't figure out how to combine the two different waveform types...can anyone give me a hint on this?
Thanks for your help,
Claire.

Hi ClaireJ,
Sounds like a reference clock conflict. This KnowledgeBase (KB) talks about this error when using simultaneous sampling. Also, might want to check the device routes in Measurement and Automation Explorer (MAX) as discussed here. Finally, if you are routing your PFI line over a RTSI connection, this error can occur. This KB discusses it.
As to your second question, this post should help.

Producer consumer with analog and digital inputs and outputs

Hi everyone,
I am working on a control system program for some practical test work. Currently I am working on the data acuisition component of the Labview program. My architecture is produced-consumer loops with a que. My system will have analog inputs, analog outputs, digital inputs and digital outputs. It's not a time critical sytem, but I would like all of the data acquisition to be synchronised. I have attached my program as it is at the moment. I am having trouble getting all of the data into the que since I have two data types. Also, I'm not sure if i've synchronised the four read/write sequences correctly. I would greatly appreciate if somebody could take a look at my program and give me some advice. Thanks in advance.

control_v2_DAQ loop.vi ‏46 KB

Robert, the specific error that I get is:
Error -200462 occurred at DAQmx Start Task.vi:6
Possible reason(s):
Generation cannot be started because the output buffer is empty.
Write data before starting a buffered generation. The following actions can empty the buffer: changing the size of the buffer, unreserving a task, setting the Regeneration Mode property, changing the Sample Mode, or configuring retriggering.
Task Name: Heater testing lab digital outputs
This error occurs at the 'DAQmx write.vi' function. I just want to sent one sample per second, for each channel. I would like the producer and consumer loops to each run once every second.
I have attached part of my code with just the data acquisition and writing. Any help would be greatly appreciated.

Analog to Digital Passthrough with Sony

In all earlier versions of iMovie up to 4, I've been routinely putting our analog tapes directly into iMovie through our Sony camera (TRV330, a digital camera, but using our older Hi8 analog tapes from an older Sony). I read somewhere that ALL versions of iMovie after 4 no longer have that capability to allow analog signal pass through without an A/D convertor straight into iMovie. True or false? And, does anyone know about the dreaded iMovie8? Can it do that? Thanks.

Last year I used my TRV530 with iMovie HD '06 to digitize all my parents video, which was shot with an analog Sony Hi8 camcorder. It worked great, had no problems. So I think you should be able to do it with your 330 also.
On the other hand, I wasn't able to use the analog pass-through capability to capture video from the camera's analog inputs. So when grabbing stuff from an external video source (VCR, TiVo, etc), I had to do it in two steps: first record it on tape with the 530, and then import it off the tape into iMovie '06.
I don't have any way to test whether iMovie '08 can pull stuff off Hi8 tapes, since all my tapes are digital. I would be disappointed if it no longer worked, but with all the other things that were dropped in '08, I can't say I'd be completely surprised.

NI USB-6501 - 24-line Digital I/O (NI-DAQ) with LabWindows/CVI 7.0 ?

Hi
Can I use a recent NI USB-6501 - 24-line Digital I/O (NI-DAQ) with LabWindows/CVI 7.0, even if Labwindows/CVI 8.x is required ?
Thank you
Dayn

Hello.
In DAQmx Readme, you can see which version of CVI are supported by the actuel DAQmx version. For a 6501 card, 8.7.2 or 8.9.5 DAQmx versions will work.

Analog to Digital VI

Hi
I am using analog to digital converter VI. In that VI, I see all parameters except sample rate. An ADC should always come with sample rate like 10KSPS,1MSPS. Can you tell me how to control sample rate of ADC. I have attached snapshot of my code.
Solved!

ADC_Sample_rate.JPG ‏54 KB

If number of samples per second is fixed( which is adc sample rate) and if we change the frequency of signal , number of capture points should change.
Example : If frequency of triangle signal is reduced by half, then number of samples captured in one cycle should be double.
Is this way simulated signal VI works/Designed?

How to trigger a TTL output with an analog input

Hello,
I have an apparatus for measuring the flame speed of various hydrocarbon/air mixtures. The chamber uses central ignition as the means for igniting the mixture. My goal is to film the ignition process with a high speed Phantom video camera. I control the ignition with an analog output signal from a SCC-68 DAQ. I would like to trigger the camera with the same signal that triggers the ignition sequence. The camera is triggered with one TTL pulse so ideally I would connect the output analog voltage signal to an input analog voltage port that would be used to trigger a counter output that generates one pulse.
I have a sample VI that triggers a digital pulse each time the analog trigger level is met and it works for what I am trying to do but I do not understand how the two channels are connected. I also can't figure out how to make the VI end after just one pulse. In the VI the digital counter is supposedly triggered using the /Dev1/ai/StartTrigger slot on the DAQ but nothing is connected to this slot.
I need to first figure out how to make the output_pulses_on_sine_wave.vi terminate after a single pulse is generated. Then I can try to incorporate it into the VI that I use to control the ignition and measure the temperature and pressure once the mixture is ignited.

I am using the USB-6259, sorry for the confusion. I would be nice if I could trigger with an analog signal to the ignition system but it is controlled with a high voltage relay that operates when 12 volts are supplied to it. It really isn't a trigger as much as powering on the high voltage relay. To control it, I have a 12 V supply line that is switched closed using a SCC-RLY module. Could I somehow connect the 12 V supply to one of the buses and use a digital trigger to supply the 12V on command to the high voltage relay?
Thanks for the quick response.

Spartan e3 Analog 2 Digital

Hi,
i've a problem concerning analog to digital conversion using my spartan e3 fpga.
I set the PreAmp as recommended in the User Guide and want to start analog to digital conversion.
I also disable the other SPI devices in order to read out the MISO properly. But when i've no signal neither on
ADC A nor on ADC B i can read out values, which a different from zero. And the most confusing thing is, that
the values are changing with the time.
I also use a 34 cycles to read out the data properly.
Best regards,
Steve Ness

Hi Steve,
an analog-digital converter needs a input source with a well-defined impedance.
If you have an open analog input (floating) the ADC provides you with any value. Mostly this value changes slowly.
More details you can take from the following documents:
Troubleshooting Unexpected Voltages, Floating, or Crosstalk on Analog Input Channels
http://digital.ni.com/public.nsf/allkb/B9BCDFD960C06B9186256A37007490CD
You can test the analog input with a battery.
I hope this helps.
With best regards,
Ralf N.

Can I use a DAQ with my CCD?

I have a multifunction DAQ card and LabView 6.1. I would like to capture images using a CCD camera and am hoping that all I need is software, is this available? Do I need a new card and if so which one?

If your camera is analog, you can use you multifunction DAQ card to read in the analog signal. You will have to monitor the signal for the H-Sync and the V-Sync pulses and then convert the meaningful analog picture signal into digital values. For more information on the analog video signal please reference the following document:
Anatomy of a Video Signal
If the camera is digital, you will not be able to read in the signal with the multifunction DAQ board. The multifunction DAQ boards can perform static digital input and output (software timed). For reading in a digital signal you will need a hardware timed digital acquistion. Our
DAQ boards in the 653x family can be used for hardware timed digital input and output. In this situation, you would use the pixel clock of the camera to time the acqusition of the 653x device.
If the camera is analog you should consider purchasing one of National Instruments framegrabber boards for you acquistion. These boards are designed specifically for this purpose. (NI 1409 or NI 1411)
If the camera is digital, I would suggest visiting our online camera advisor to see if your camera is compatible with our digital framegrabbers (NI 1422, NI 1424, NI 1428)

Analog TV, digital TV antennas

I've been getting my cable through Comcast for awhile now. I used to have more extensive cable channels but with their switch to digital, my channels have dropped down to just the free channels and a few other meaningless channels that no one ever watches.
I have looked into pricing for the more expensive cable packages through Comcast, Dish, DirectTV etc. and have decided that I really don't want to spend the money on that given my TV viewing habits and my ability to view programs on the internet. The only channel I will actually miss is the Fox News Channel.
I am paying $19/month, including taxes, for the channels I *think* I can get with an antenna for free. I have older TV sets all purchased 10-15 years ago that still work fine. I don't have the ability to put a massive antenna on my rooftop. Can anyone make any recommendations for a TV antenna that will work with my older TVs? Or, does anyone know whether the new TVs come with built in antennas? I am not adverse to buying a nice new TV for my living room. I heard that [another retailer] has a bunch of inexpensive TV sets if BestBuy doesn't have what I am looking for.
In the end, anything I choose will end up paying for itself - eventually - once I stop paying Comcast $19/month for nothing. I just need a direction to head in. This is not something I know much about.

Yes, with older TVs you need a converter box. Newer TVs all come with built in digital tuners. You'll get far higher quality if you get a new HDTV.
Note: Unlike the old analog signals where image quality depended on signal strength, with digital signals you pretty much either get the signal or you don't.
If you click on the antenna reccommendation on antennaweb.org (in your case "yellow UHF"), it'll give a more detailed description - http://www.antennaweb.org/aw/antenna.aspx?color=Yellow . Yellow UHF is a category of antennas - small omnidirectional. Good news is that this means your TV stations are close by, as that is the smallest antenna category there is! Basically, any antenna made by a member of the CEA will have its category on the packaging.
If mounted indoors, you may need to go one or two size classes up from the CEA reccommendations.
I reccommend antennas from the following manufacturers: Winegard, Channel Master, Antennas Direct
I reccommend preamps from the following manufacturers: Winegard, Channel Master
You say you can't have a large roofmount antenna - what about a smaller roofmount antenna? Getting the antenna on the roof helps a LOT.

MBP video out to TV using DVI - both analog and digital?

I have a Macbook Pro 10.6.4 2008 Model with details are below on graphics card and display options. I am trying two hookups to televisions which may or may not be possible. Can anyone tell me if my DVI output on the macbook pro is capable of delivering an analog signal to my old sony tube tv with component inputs? Second part of my question is do I have the right dvi cable. I purchased a cable with 24 + 5 pin. This cable does not produce a picture on my analog or digital television. Just snow on the analog and no input on the digital. The cable that came with my macbook pro is a DVI to VGA converter and seems to be an 18 + 5 pin plug....with a few pins missing in the middle. Should I buy another cable with the 18 + 5 pin DVI to component or buy a cable to connect the supplied DVI to VGA converter - VGA to component. Please help I'm confused on many fronts.
Thanks

I made an account and am replying to this because i have the exact same computer as you and i was also at best buy at around 3pm wondering the exact same things you were! The DVI port on our MacBooks are different than the standard DVI ports. Freaking weiiiiiiiiiiiiiird! Get out of my head!!!!
I ended up buying a VGA cable and using the converter that came with my MBP because the DVI to VGA cables at Best Buy had a different VGA than what the MBP has.
Our goals were slightly different though, I wanted a cable so i can connect the MBP to my Toshiba 42inch HDTV. VGA works but doesnt support 1080p, only 1024x768, which is not a fullscreen resolution. So i will be returning the VGA cable tomorrow and looking for a VGA to HDMI cable, if that exist.
So, to answer your question, YES, buy a cable that has the same ports as our adapter, or just use the adapter that came with the Macbook.
