Record signal

Hi,
I am Chan. Recently, i have bought a NI card (PCI 6120) to do my soil testing research. I need this card to generate (voltage output) continuous sine wave to piezoelectric (transmitter) and then record (voltage input) the signal from piezoelectric (transmitter and receiver). This mean the NI card (PCI 6120) has to generate 1 output signal and get 2 input signal. All the signal are in voltage. The piezoeletric is penetrated into a soil sample. I would like to study the wave signal travel in the soil sample from transmitter to receiver.
I did try using the NI card to generate a continuous sine wave and record it using a PicoScope oscilloscope to record the signal. But, the signal is not smooth and look like a staircase.
I need your help to write me a labview (vi) to generate (1 output) the continuous sine wave signal (maximum 5000 Hz) and record the signal (2 input) (like oscilloscope). Then, i need this record data for my analysis. Labview is new software for me, therefore i need time to study it. But, now i need the (vi) to run my soil testing test first. I do wish to have more time to learn. I do appreciate your help. Thank you. Best wishes.

Hi Chan,
This attached VI ( taken from Labview examples )should do the kind of synchronised Generation and Acquisition that you want to achieve.
Regards
Dev

Want to get a recordable signal

I recently purchase an M-audio fastrack pro audio interface and attempted to configure it into audition , but i have yet to
get a recordable signal . could you walk me through the steps in trying to get a signal.
I wanted to know if it was possible to record into the Adobe Audition 3 software in 16 bit quality vs. the standard amount available
now?
Will Adobe Audition 3.0 recogninze my interface ( int he device properties tab), to do some work in edit and multitrackview, if say
my interface is a protools digi 002?

To get your M-Audio Fastrack to record in Audition you need to configure it in Edit/Audio Hardware Setup menu. When it opens in the Edit View page you should be able to select M-Audio USB ASIO from the drop down list in the Audio Driver slot. Having selected that if you click on Control Panel the M-Audio panel will open where you can select your inputs and outputs and Sample Depth 16 or 24. The Control Panel should show connected at the top right if your USB Fastract is working. Close the Fastrack Control Panel and then you can check at the bottom of the Audio Hardware Setup panel which input and outputs Audition will use (01S is channel 1 stereo or 01M is mono). You will then have to select the Multitrack View to set up the M-Audio for multitrack use as well. Click on Apply then OK to close Setup and return to Audition.
When you select New file in Audition you can select the sample rate you want to record at and the bit depth, 16 or 32. There is not much point in recording 16 bit as Audition works at 32 internally and it is better to keep your files at 32 bit to retain quality until you have finished processing them. You can then always save them out as 16 bit when you need them as such.
I am afraid you won't have much luck with using a Digi 002 as a source for Auditon although it can sometimes be made to work with some difficulty. Digidesign have so set up the 002 drivers to only really be compatible with ProTools.

Software that catch record signal to re-route?

I'm looking for a prog that could capture the record-signal and route it to line-out (as this could solve my problem of only being able to record my SPDIF-in on Soundblaster MP3+)
anyone know of such a prog?

No recording signal on new Garageband - Help!

Hi there - prob being stupid but need help? I recently got a new iMac with the latest Garageband on - used to be able to poodle away without probs on my old 2007 version but I am struggling. I don't seem to be able to get a recording signal despite the track to which I am recording seemingly being 'armed'. Here's what I am doing;
1. Creating a new track
2. Selecting the guitar
3. Connecting the guitar via an Apogee One interface.
4. Guitar seems to register against track but with little input volume? I've checked and double checked things are turned up and also tried with manual and auto recording level.
5. I arm track - when I start the track is clearly recording but it's not picking up the signal from the guitar and I just can't understand what I am doing wrong?
6. Have tried other guitars - still the same.
7. Also, despite clicking the monitor button I am not getting anything.
Totally exasperated so if anyone can gfive me some idiotproof guidance I'd be mighty grateful?
Thanks

why did it work OK last week when the lock was in place?
When the enclosure lock is locked, the server will only recognize devices that are attached at boot time. It won't recognize any device plugged in after the server has booted.
Is is possible that the devices that were working last week were attached at boot time?

My recorded signal is not sounding like the signal I am monitoring.

My recorded guitar is not sounding like the signal I am monitoring. It sounds very good when recording, but lacks energy and detail when it is played back. If I am using input/direct monitoring am I also bypassing the Analog to Digital converters? Could this explain the difference in sound quality?
Would it be the same to monitor a signal directly out of the sound card and to monitor "through" Logic?
My sound card is a Presouns Firepod.

No.

Consult the manual of that device, to see if you can learn from where in the signal chain it gets your direct monitoring from --- PRE conversion or POST conversion... My bet is that it is pre conversion.

Host of issues including recording, signal loss etc

Please help!!! I'm at a loss here! I am having a number of issues with one particular skybox. It will not record properly, some recordings it says 'This program cannot be inserted into the planner', when it does decide to record, the red light doesn't appear on the skybox, or else the Sky box shuts down and say there is no signal. Things that were supposed to be recorded have failed continuosly. I have done a planner rebuild and system restore (lost EVERY program), and NOTHING works!! When I try to view channels, and press the 'i' button, no program synopsis appears. Rcently, about 2-3 weeks ago, our TV was moved up to the wall and the skybox was moved to a shelf. Does anyone have a picture of what the leads should look like? We have the necessary leads in the box, and a white lead connected from the attic, sky dish, into the skybox, but before the issues happened, it used to be in the TV. I'm at my wits end!!! Please help!

The signal says, in order : nothing, nothing, not locked, null, nothing, nothing, not locked, not connected. What can this mean??? From the time during the last post, I messed around and the two cables came out of the metal casing.Your Signal readings above mean that there's no connection with the satellite dish, maybe because your cables have popped out of the F-plugs. If so, make sure the copper braiding is folded back over each cable, then screw or twist the plugs back onto the cables. Some pics here

Re: HDR5010KB Digital Recorder - signal doesn't always come through using HDMI

Hi,
I bought the above product in October. Since then I've had an intermittent problem. When switching to the AV channel on my TV, (a Panasonic TX-P42S20B) the signal doesn't always come through when using the HDMI channel (I also have it connected via a scart, and that always works so seems to be an HDMI problem.) It's particularly apparent when the recorder has been used for a while (either for recording or playback.) It's not overheating (or if it is, not to the degree I'm getting a warning message), and turning the power off at the mains seems to rectify the issue, but it's a pain.
I've tried switching the hdmi lead, as well as trying different AV channels on my TV and it hasn't helped. Is this a common problem or do I have a faulty unit?
Any suggestions would be appreciated

no, everything else works fine. I've tried swapping cables & hdmi sockets on the TV with no luck. One thing I have noticed, the recorder also works as a hdmi hub (there's 2 additional inputs). Switching the output to one of the other hdmi's, waiting, then switching the outputback to the recorder usually resolves the problem. it's just a pain having to do it

Recording/Signal issue

I've recently had this issue where if a recording is happening, other channels' signal drop off? its very weird and as soon as i stop recording and turn to a different channel, all the signals come back. is this a problem with the box and i need a new one?
any help would be great, thanks!

Hi Silverscreen,
Are you still having this problem? If so, which box are you using (Black/Silver)? Have you noticed any patterns with what's happening (i.e. certain times/channels/programmes)?

No audio recording signal

My mics are fine, i can make beats but vocal recording is impossible. what do i have to click on. please be as precise and basic as possible.

Explain better! What interface are you using and through which channels in your interface are you bringing your input in. Make sure that if for example your mic is connected to input 1 on your interface, you select input 1 on your audio channel in Logic from the pulldown menu on the channel strip.

Y ribbon cable to record signal with 2 computer simultaeously.

I need to read an external pressure
signal with 2 computers simultaeously.
I already have this working with one
computer with a DAQCard-1200 and a
50pin female ribbon cable. But I was
wondering if a "Y" ribbon cable is
available so that I can read the
pressure with 2 computers. Or would
I have to make my own "splitter"
cable to read the pressure with 2
computers.

Don't connect the two 50 pins from the DAQboards together, because this means you will connect +5V, digital and analog outputs. Sure there will be no surviving boards.
I would just tap the signals you need from the pressure sensor, I guess two analog inputs (differential) and a ground-signal and route them to a screw-terminal box that is available for your 50 pin cable. Such a box is always handy for quick but firm connections and measurements.

Cannot get a recording signal for acoustic guitar thru Mbox 2. All cords, batteries, etc are checked and good.

Done this a million times. Today it decides to ignore the input. Done all the usual checks in system preferences, batteries, cords, rebooted, etc.

Thanks for the help mate, just gave the speed tester another bash and managed to get something back.....As predicted, results werent exactly brilliant....

Apply FFT on recording signal

Hi,
since the ios 4 we can take advantage of the accelerate framework which holds the vDSP API and this has a FFT in it. I want to use that for the microphone input and filter low tones with a low pass filter. can somebody explain me how to apply the FFT to my microphone input and then deal with the data from the FFT or does somebody has a link for me explaining that?
would really appreciate that, thx.

How can I use the USRP to record a signal using its two RX port simultaneously?

Hi.
I am trying to record a signal using two horn antenna. The reason I need two antenna is to cover the wide frequency range (DC-6GHz). one antenna is covering DC-300MHz and the other one covers 300MHz-6GHz. So I need to use two RX port of USRP at the same time to record the signal. I have two questions:
1. Does any USRP in the market capable of covering this range of frequency?
2. Is it possible to use both RX port at the same time to record signals as I described? If not, how can make that happen?
P.S. I have two NI2920 USRPs and two N210 USRPs in my lab.
Thanks in advance for your time.
Sam.
Solved!
Go to Solution.

Hi Sam,
To answer your first question the USRPs that you have cannot reach the frequency range that you want. There is not a USRP, to my knowledge, that can reach this range in one device.
Also note that you cannot use two RX sessions for two different ports at the same time using LabVIEW and the USRP driver. If you want to use both RX lines you will have to run one session with one line, end the session, and then start a different session for your second RX line.

K8T Neo2 - Problem recording a signal

Hi,
I've plugged an external music source (CDplayer, MP3 player ...) to the mainboard blue jack. I can hear this sound with the PC speakers (which are plugged on the green jack) => it means that the sound from the external source is clearly entering to the computer.
When I try to record this signal the result is a loud sound and nothing else. In the software used for recording (I've tested several softwares, for example Pinnacle Studio9 or JetAudio, function Record), changing the volume of the source (blue jack) didn't not change the level of the signal .. always to the max.
If I try a microphone, same result impossible to record (but I can hear the Mic sound on PC Speakers).
I've tested VIA sound drivers (from MSI) and Realtek sound drivers (from MSI and latests realtek).
Any information is welcome :-)
Thanks
The computer is running WinXP Home up to date.The Motherboard K8T NEO2 6702E v1.
Sound recording was working few months ago

nop. have you tried to play with realtec ctrl panel settings?
not yet as I'm currently trying to see if I've the same recording problem with a Linux LiveCD (Knoppix).
Not easy to find a recording software which runs with livecd ... I'm not enough strong in linux to use command line for recording signals from a specific plug of the onboard soundcard.
I switch back to windows again and I see the ctrol panel.

How can I select the time values of a signal and connect them to the y-input of a divide command?

Hi,
I have an analog signal connected with a threshold peak detector. The counted peaks shall be divided by the total time of the recorded signal. My problem is, I don't know how to connect just the the x-values, i.e. the time component of the signal, to the divide command. I have no idea how to "split" the signal so that I don't have the whole signal but just the time in seconds as an output of the measured or filtered signal sub-VI, respectively.
Does anyone have a hint?
Thanks for your help,
Philipp

Hi Phillipp,
do you mean you have a waveform and you want to get the components? In this case "Get Waveform Components" should work.
