Convert sine wave to digital output

Hi,
I'm using pci-6251 and Labview 8.
I have an input analog sine wave which I want to convert to an output TTL pulse (with the same frequency). I also want to be able to control the width of the TTL pulse.
Can anyone give me some advise?
Thank you,
Shafran

Shafran,
This KB should be a great starting point for your application. You can change the width of the pulse by changing the duty cycle.

Using USB-8451, and AD7747 from Analog Devices to measure capacitance and convert the capacitance to digital output

Hello,
I am new to LabView and data aqusition. I have LabView 8.5.1 installed on my laptop, and I studied the Getting Started document of LabView, except the data aqusition chapter.
I have microfabricated a differential capacitive sensor, and now I want to test the capabilities of my sensor.
After asking NI engineers, I have been suggested to use USB-8451 with AD7747 (24-Bit Capacitance-to-Digital Converter) from Analog Devices because AD7747 has I2C serial interface.
I have ordered USB-8451, AD7747, and Evaluation Board for AD7747. And I am waiting for them.
Are there any suggestions about how to connect my differential capacitive sensor to AD7747, and eventually to USB-8451?
You may want to know some further information to answer my question:
*The sensor is similar to the sensor on pages 501, 514, and 515 of "Microsystem Design" book from author Stephen D. Senturia.
*The datasheet for AD7747 can be reached from this link: http://www.analog.com/static/imported-files/data_sheets/AD7747.pdf
*My purpose is to make a very precise and accurate "displacement measurement micodevice" by using "the change in the capacitance" during the motion of the mobile fingers of the sensor.
As an initial challenge for myself, I will feel satisfied if I can measure the capacitance change in my sensor when I apply an external mechanical disturbance to my sensor. For example, there must be a change in capacitance if I just swing my hand from top of the sensor region.
I am looking forward for your reply,
Thanks in advance,
Sincerely,
sriverfxtr

Hi Aaron,
Here you go, this is made with a USB-8452.
When you run the code tick the power en dac enable box on.
Maybe you can help me with my problem, I want to use a fiber to sense light from a led.
Do you use any fiber hardware with the TCS3414?

Can i convert a wav file to a digital signal without using DAQ?

i tried the coversion of a sine wave to digital signal, ofcourse it doesnt work on converting wav file to a digital signal. i am also new in labview. i tried to explore it but there are many functions that i can't use.
so my these are my questions.
1) is a .wav file is an analog signal?
2) can i convert it without using any DAQ device?
tnx guys! i'll post the programs that uses quantization of a simple sine wave. i tried it to .wav file but it didnt work.

.WAV is a digital "signal". It uses Pulse Code Modulation to encode analog signal. You don't need a DAQ device to "convert" it to analog. Any computer with a sound card, and media player can "convert" a .wav file to the analog audio signal it represents

How to output a TTL signal from a sine wave [Please Help]?

Hi evryone!
I am a bit lost...
We make the acquisition of voltage (sine wave, 3Hz) which I simulated by a waveform generation in my VI. We want to convert this analog signal to a TTL and output it with a multifunction DAQ (6230).
I only used Analog to Digital.vi and DAQmx write.vi and I can't get it to work... I get a TTL which is not 3Hz and only If I input a frequency like 3.07 and not 3.00 !!
Did I forget something ?
Thanks for helping
Christophe

In your vi, you don't have DAQmx Timing setup. I don't know what the default value is. But the timing determines how fast the DAQ will output values. If not set correctly, you may see slight change in the output frequency. Another thing is that the timing is based on a master clock, like 50MHz. The clock gets divided down until it gets near the desired setting. So it may not be able to achieve 3KHz exactly. If you are getting 3.07KHz, this may be why. I don't know if there is anything you can do about it. Try using the timing vi and setting different sample rates.

How can I output successive sine wave sequences?

I'm using Labview 8.2.1 and I'd like to output sequences of sine voltage waves to a motor, each sequence being associated with n number of cycles at a given frequency and magnitude. For instance, three 0.5V sine cycles at 1Hz followed by three 0.2V sine cycles at 10Hz - no waiting time in-between and all data saved to a given folder. I've been using the 'Cont Gen Voltage Wfm-Ext Clk.vi' within the example library. I added to that a stacked structure thinking that I could copy-paste the first sine sequence to the next frame - changing only the frequency+magnitude values of the sine wave - but I couldn't get the second sequence to execute. I tried out other options with different timed structures but it was not successful either. My block diagram for now looks like this:
What fundamental steps/elements am I missing?
Thanks for your help,
Thibault.

Instead of using frames let’s try something a little bit simpler. First your generation is set to continuous so it will never go to the next frame until the first task is done.
You have two options to solve this problem:
1.       You build the waveform the way you want it, and then you start the generation with the whole waveform load into the card. Just need to make sure this will limit the size of your waveform to as much memory you have on your card. Advantage about this approach is there will not be time gaps between one signal and the other one
2.       The other option is to start the generation with one waveform stop it and start it over with different specification. Basically what this is what you are trying to do, but you need to change your generation to: “N samples”. One thing to consider about this approach is that your signal will have a gap every time your task is started and stopped.
Let me know if it helps
Two point to remember, this is a question that can be answer more correctly in DAQmx discussion forums not, labview and next time if you can reduce the picture width to less than 500 pixels.

Will the Ipad power adapter operate safely from the modified sine-wave output from a 12VDC-240VAC inverter?

Will the power adapter for the Ipad Air operate safely on the modified sine-wave output from a 12 VDC-240VAC inverter?

I am not sure why you want to do that...the power adapter takes 100-240 volts AC at 50-60 Hz and converts that to 5 to 5.1 volts DC at about 2 amps. Why are you inverting 12 VDC to 240 VAC then back to 5 VDC?
It should handle that easily, but seems like a long round about way of getting there.

Analog input to modulate triggered sine wave analog output

I'm new to Labview and having trouble getting my app to program correctly.
I would like to use an analog input (AI) to modulate the amplitude of a
100 kHz sine wave and output the results to an AO. This is a real
time application: the AI will change every few 10's of ms so during one
"cycle" the amplitude will be modulated many times. Plus, the entire AO
will be triggered on and off with a digital input TTL trigger. The
waveform "cycle" will run continuously and so will the AI.
I've used an example included with Labview to read
the AI and a separate one to generate the sine wave and trigger it on
and off, but cannot combine the two together. I assume what I need to
do is implement a loop properly but when I try I can only trigger the
AO on and off and the AI does nothing or is static. I assume that the
vi just takes one point from the AI and uses that to determine the
amplitude of the sine wave, but doesn't "redraw" the sine fast enough
to respond to the AI changes.
Thanks,
Ethan

Hal,
I do not think I have Labview Realtime (unless it comes standard with the full version of Labview ). Do I need to have that? I have a 6251 DAQ board.
I've enclosed my program- it has the name of the original included program in its file name so you can see that I didn't do much to change it. I made some changes today (to make it non regeneration) but now can't get the AI to read at all. And I have no idea how to modulate the sine amplitude using the AI.
The sine wave works fine and triggers as needed. The one problem is that the sine wave doesn't end at the same point (phase) each trigger period so during the times between triggers the DC level on the AO is variable (which I do not want). Is there a way to end the sine wave at the same phase (at the zero crossing) while still triggering it with a digital input.
Thanks,
Ethan

Simultaneous analog output 1k sine wave and data acquisition

Although many topics of simultaneous analog output and input can be found in NI Developer Zone, I have not found a case similar to my project. I'm trying to generate a 1kHz sine wave by using the analog output of NI DAQPad-6070E, and acquire one channel input signal simultaneously. I found most of the examples can not work properly above 100Hz. Any suggestions are welcome. Thank you.
Jian

I have sucessfully solve the problem when I observed the increase of
scan backlog number. Simply increase the buffer size of AI/AO and you
can make the 1kHz sine wave output and data acquired properly.

How to generate multiple digital outputs (square waves delayed) at 50 kHz?

I would like to generate 3 digital outputs like the picture attached at 50 kHz. Using the "digital pattern generator (marching values).vi", I can generate 3 digital square wave but without the delay time. How can I do that?
I'm using the card PCI 6034E.
Thank you

Hi,
the digital pattern generator (marching values) only shifts the binary value of the first signal and sample to the next signal/sample.
Have you tried generating your waveforms via build waveform and use t0 terminal to change the lead delay?
In general, this DAQmx example could be helpful which you can modify to your needs.

Outputting sine wave to motor -- While loop placement?

I'm having trouble creating a basic Labview program to drive a motor with a sine wave. I'd like to output one sine wave at a time to my motor and look at the response to eventually get a Bode plot. I'm using the Sine waveform VI and I've got a PXI-7358 controller card.
I'm having trouble figuring out what goes in the while loop. I'd like to output, for example, a 10Hz sine wave to my motor. But when I create a VI as shown below (& attached), my output waveform frequency is nowhere near my input frequency. When I type 10Hz I get no movement out. At 10.01 Hz input the motor oscillates at a few Hz, and at 10.1Hz input the motor oscillates wildly. I don't think it's a problem with my motor or my PID settings, because even when I eliminate the motor commands altogether (second figure below), I get the same unpredictable relation between the frequency I type in and the Waveform graph.
It seems that the output waveform depends on some sort of difference between the while loop execution rate and the PXI-7358 command generation rate. It seems to me that the Sine Waveform.vi should be outside the while loop, but in that case the Load Position.flx only seems to grab one position. Is there a good way to have direct control over output frequency of the sine wave?

Hello Yun_Zhu,
Your VI looks like you started from an example, and you are on the right track.
To clarify are you trying to synchronize the input and the output waveforms? If you you will need to share a time base and a start trigger. Check out the synchronization examples from LabVIEW

How to output square wave with pci 6110 from digital output

and the frequency of the wave should be variable and quite precise.

"from digital output" is not possible if
your timing req's are less than a second
and
you are not running Real-Time.
It can be done from the analog output port.

How do I synchronize a pulse output to a sine wave input on a pci-6602 card?

I have a sine wave from a function generator as the input on the source of a counter. Input frequencies vary from 2-60 kHz. I want to produce a pulse train at a different frequency (10 Hz), but in phase with the sine wave. I have only been using Labview 5.1 for a short time. I am using the PCI-6602 card with a SCB-68 connecting block.

Hello;
Unfortunately, you can't connect a analog sinewave to the counter source. Counters only work with digital TTL signal type. To accomplish that task, you will need a MIO board working in sync with the 6602 you already have.

Unable to read the frequency from this output sine wave of amplitude VS time

my programe reads through a labjack programe works up until the LJ stream graph process reads to "scaled data v's seconds" graph.where it outputs a sine wave (amplitude vs time)
for some reason the "freq. amp." analyser won't read the frequency correctly. when i run the programme it outputs a frequency of zero.
note: the amplitude is reading correctly
see both programmes attached..................

What is the idea with these VIs?, tell me more, please.
