• Hanging tool select disabled but time always snaps between sampling Points

  Hello

  In the Waveform Editor, when I Zoom in directly on the waveform, the points become visible. I have 3 Q: -.

  1. What are these points
  2. They can be changed
  3. How can I select (with the Selection tool) anywhere on the waveform?
     1. I deselected waspish and yet I am with zoom basically I can only place the time tool (TST) between the points visible, i.e. hearing snaps TST so I can not place exactly there where I want

  Thank you!

  The points show the individual samples in your digital recording.

  Jump to your last question, you cannot place the time between samples picker because samples are smaller individual representations of the original audio.  the lines between the samples are an artificial creation, making a waveform of samples.   There is an excellent video showing how digital audio works - I recommend highly a cup of coffee and a viewing: D/A and A/D | Digital Show and Tell (Monty Montgomery @ xiph.org) - YouTube

  Spacing of samples is determined by the sample selected speed which, in turn, is controlled by the clock system (Word clock).

  As for the editing... not really.  Older versions of hearing used to allow you to enter a sample and move it upwards or downwards, but the results could be unpredictable - under Nyquist theory there is only one waveform (i.e. one correct) which corresponds to the sequence of individual samples.   Changing a single sample (or even two or three) can force the system that analyzes samples and draws the analog waveform by doing a few calculations confusing, incorrect.   If you watch the video above and "read between the lines" you can see why that would be.

• Single sampling Point Acq

  Hello, a little info on my system and I to start. I'm under LabVIEW 8.6 and using the NI USB-6259 box as my DAQ hardware. I'm new in the world of only having been LabVIEW use this configuration for 3 weeks (but a nice step to the top of the Win95 system I was using).

  I'm trying to order and circuit operating at 8 kHz. I want to read in a voltage of the circuit, detect a break in its derivative and then send the output voltage back into the circuit based on its signs at these crossings. To safely control circuit, I need to taste well above 8 kHz.

  The issue I'm having is speed limits due to a loop based around a DAQ Assistant of "1 sample (on request). I read a lot of messages saying to use timed HW sampling but I do not think that my DAQ hardware supports it. I used clocks to get a rough idea that my loop runs roughly 25 Hz.

  I don't know if the problem is in inefficient coding or limitations of my hardware and software. Attached, you will see my current VI.

  You're right, you use the acquisition of timmed softwared, you want to run in continuous mode, The 6259 should be able to acquire up to 1.25 MECH. / s.  Try to put it in place with the daq assistant since you're new to labview, or look at examples of analog acquisition.  essentially, you want to read in a loop using buffered continious CQI, then send the results to your vi loop or slave to the processor.   I would like samples at 5 - 10 times the 8 kHz to get a good representation of the signal you.  faster that the x 10 will give you nothing but too much data to deal with.  8 kHz is not too much data and you might be able to treat it in the same line as your read daq.

• than 25 ns sets sampling rate...

  Hello

  I'm trying to test the sampling rate of chassis cRIO 9103...

  I created a simple FPGA project, for sampling sign this clock frequency of the FPGA equal to 40 Mhz (on by default). I applied 1 Mhz square wave to pin MISO DIO6/SPI, place one of the slots on the frame... I put a tick 'loop timer' in ' ' loop for every moment of picking (totally 32 sampling point).

  input signals a cycle = 1000 ns (1 MHz) and I m planning see samples every 25 ns (40 MHz) on the graphical waveform. But the chart shows me only 10 points for 1 cycle like taking samples of every 100 ns instead of 25ns. (FrontSamplingRateObservation.png)

  What is to be? If so, how can I get faster sampling rate...

  I joined .vi photos of the project...

  You can consider that the only timed cycle lines and the pipeline of the operation.

• AO with sample Counter clock

  I have a problem with AO with counter-sample pointing SMU-6124 in Labview 8.6.

  The attachment shows my entire code for this.

  When I run this code, I've never met no error, but no output (expected in AO pulse train).

  Strangely, in the title to "highlight the execution" for debugging, the output has been shown in my oscilloscope (of course, no errors in labview).

  What's wrong in my code?

  Labmaster.

  *) Please run 'merge.vi shape pulse' beware.

  Hello labmaster,.

  I took a peek at your code, and a question, is that you use the done VI DAQmxBase is task rather than the fact VI DAQmx is operational. You cannot combine the DAQmx and DAQmx Base API and this could be the cause of your error. When you use this VI in DAQmx application the task performed? output will always return the value true. This return value is prevents your loop and resulting in your cleaning tasks before all your data is generated.

• How to pin a point to move the list that does not appear in the common?

  The answer depends on what type of element you want to pin.  The only type of element you mentioned being a folder, you can easily do what you're wondering now and does not need to wait for a later version.

  In the 8 Windows desktop, when you drag an executable file (or shortcut) on the taskbar, a message appears that says "PIN to the taskbar.

  If you drag a document file (or a shortcut), the message will say "pine [associated application]"-in other words, "[name of the default browser] pine" for a html, "Pin to Notepad" file to a txt file, etc..

  For a folder, File Explorer is the associated application.  Therefore, if you open a file Explorer window, look for the desired folder and drag it to the taskbar, the message that appears is "PIN to the file Explorer."  Just click on it, and it will appear in the jumplist FE, above the frequent places, in a separate section called "Pinned".  You can drag things and down from there to order at your leisure.

  (The Control Panel, even if it is displayed in FE as 'File system', only let you pin on the desktop, for not not FE jumplist.)  There may be other special cases like this; I don't know, but it works usually as I've described, including for other system folders.)

  Just to be clear, I am a new user of Windows 8, far from being an expert.  I only know how it works because I heard today by trial and error.  So there may be more to what I can't help with.

• Stupid Photoshop. Clone tool does not. That means "could not use the clone stamp because the area to clone has not been defined (option - click to set a point source)" means?

  Please help and bear with me, I can not know what you are talking about. Total newb

  Nice day!

  The Clone Stamp tool is intended to be used to paint the parts of an image on one image (the same or another).

  To do this, a sampling point must be set for Photoshop 'know' what piece to be used and which is done with the Clone tool from the selected buffer, alt-click on the space provided.

• Color of these points with curves CS4

  Hi, I use CS4 and I want to do a color correction, I use the color sampler to select areas that I want to change it is to say highlights approximately 242, but I want to place a sampling point for the midtones on the RGB layers at the same time, for this, I understand that, if I hover over a sampling point and hold Ctrl + Shift , then click on what it has points of adjustment on all channels, but when I hover over my selector sample color changes from point sample to the move tool so I guess I must have hit a button somewhere but don't know where! Any help please.

  Thank you

  Russ

  I guess your work with an adjustment layer curves?

  You probably still have the color sampler tool.

  Select the eyedropper tool, or you can use the self-select-Targeted adjustment tool.

• Color Sampler script part 2

  Ok. So I'm back at it. Here's what I have a problem to find now any help would be appreciated of course.

  When I use the colorSamplers script I am able to get information on a single point. However, when you set the sampling points there is the possibility to select the single point, 3 by 3 average, 5 by 5 average 11 of 11, etc., and the average number is shown in the Info Panel. But, the script always returns the information of single point and not the average. Is it possible to obtain this information using another script that through every point with the colorSamplers [0] .move () and make the calculation in the script in order to get the average? This is how I do it now, but for large surfaces, it can become slow.

  Any advice?

  No, I don't mind at all. You can replace your scriptlistner turn off with the method DOM comes to make the code a little tighter.

• Problem of Variables HP first Solver

  I am trying to solve the following equation in the application of the Solver:

  TO / T = 1 + (Γ-1) / 2 * M ^ 2

  I previously created the following variables: 'To', 'γ' ("T" and "M" are already built into the calculator from the factory)

  If I input values to the 't', "γ" and "M" and try to solve for 'To', I get the following message:

  "Constant? The value of the equation is the same for all sampled points. »

  I noticed that if I replace 'For' for a different variable, say 'P', the Solver to get the right answer.

  Help, please!

  Hello

  It is possible that there are in the calculator as a reserved variable (constant or another unit).

• Triggering off the coast of beginning of Pulse Audio in question DAQmx...

  Hi guys,.

  First of all, it is more a matter of software than hardware, so I didn't post this specific question in the multifunction DAQ card...

  So I'll try to trigger an acquisition finished off the start of a pulse audio, however I have audio sync issues, due to the fact that it can be started before my VI runs. As noted below, the audio is generated and pulsed for 500ms on and 500 ms off the coast, and between these periods, a digital pulse is generated this way (shown in red). I have a problem to stay synchronized, due to the fact that I samples finished for 1 second of a data value, and if the USE EEG is faster than me, I can catch the pulse audio at Midway, rather than at the beginning.

  

  I'm trigger analog outboard of a sound signal of 50mV and capturing two audio channels simultaneously and consistently captures 3 digital channels when they receive the trigger of the beginning of analog input trigger reference digital edge. If digital are slaves and audio is the master in this configuration. The point of this is to get a delta timed material at the time rather than use the timestamps of windows.

  As I said, I use an Analog Edge Trigger Start to start my purchase, what triggers the digital task Digital Edge Start Trigger to start as well. How can I make sure that I start at the BEGINNING of a new pulse audio if I get out of sync, I can't understand this logic... Analog edge goes off just when it goes to the specified level, but maybe it's at half way through the 500ms pulse, so this is my problem...

  I need to be a trigger to start because I do 55 000 this test iterations in a QMH Prod/consumer model and need relaxation to be redeclenchables and start-up is only redeclenchables.

  The variability in timing you see at points 2 and 4 somewhat dictate against the possibility to set up a re-triggering precisely timed by the hardware configuration.  I think that you need to abandon the idea of making repeated sampling finished back to back and switch volleys in a mode of continuous acquisition and treatment.

  To help with this, I aim to capture the moments of digital via meter rather than DIO pulses and be ready to give up the acquisition rate noise much (if necessary) given that you said that your main concern is to distinguish between ON and OFF.

  I must configure the counter to use the Digital pulse as a sample clock and use the sample clock signal HAVE the "time base", i.e. the signal which the edges will be counted and buffered in memory.  This will give you 2 samples per second instead of 5 M and the values of the counter at these sampling points is the index in your AI data which occurred impulses.  Pretty neat and clean.  Just be sure to start the task of counter in front of the task to HAVE it.

• Incorrect writing to the file timestamps

  Hi all

  I wanted to familiarize yourself with writing data and associated timestamps in a file to verify the rate at which samples are played back in my system. As a little test I wrote a simple VI that travels 5 times and creates 5 sine sampling points. Each point has its timestamp captured and converted to seconds and fractions of a second. After the for finishes in loop iteration it writes the data of sample (line by line) for every 5 samples with their associated timestamps.

  I imposed a 1ms delay for each iteration and hoped to see the consistency between the timestamps of the consecutive samples but sometimes they are very or even identical to the previous timestamp which doesn't make any sense for me. I tried with wait times and it seems to be more precise between samples, but this result is intriguing.

  Example:

  31.209159       0
  
  31.209159      84
  31.209159      91
  31.224784      14
  31.224784     -76

  I chose not to use custom file VI writing because I had the same problems and thought that it could have better results.

  Hoping someone can clarify it or show me where I'm wrong. I have attached the VI below.

  Thank you.

  If you are using a hardware device timed, as NO hardware DAQ, you then get accurate timestamps. Everything else is a limitation of the Windows operating system. You can always switch to LabVIEW RT if you need more specific expectations.
