• Generation of signals of segment

  Hello!

  How is it possible to generate such a signal (photo attached)?

  https://pp.VK.me/c622024/v622024951/33e6f/I3zJNTMGiU0.jpg

  A link to the answer (if there is one in this forum) would be great.

  Thank you

  This may work for a graph where it will automatically draw lines between points.  But if it comes to the generation of signals, it won't look like that.

  Look at the function of ramp model.  Which allows to build the parts in signal Hill and initialize the array to build from scratch the parts and flat parts.  Then use table build with CONCATENATE entries in order to combine these tables into one.

• Could someone help tell me how can I save 100 to 200 equidistant values of a particular number % 3F

  Could someone help me that how can I save 100 to 200 in labview at equal distance from the values of a particular number? Lets assume that I have a number of 50 and I need 100-200 equidistant values between 0 and 50. I made a sample program, but it gives error of memory storage that I did not understand how to solve...

  You make the mistake to make equal comparisons on numbers floating point. It's very dangerous. Most likely, your VI will never stop until the computer is out of memory. Replace the 'equal' by ' greater than or equal to "and you should be OK.

  As you know the number of iterations in advance, you must use a loop FOR, see how far you get. In addition, your shift register must probably be initialized.

  (Of course, it is also 'ramp model' If you want a canned solution. )

• Create a table based on Max and Min

  Hello

  I found a thread fairly similar, but he has not answered my question.

  I'm building a Vi that simulates a cyclone running at high volumes of different admission. I need to generate a series of volumes of admission based on a user of max, min and interval/step input. These data must be used for the calculations and the x scale of a chart. What is the best way to do it? I could have the user specify each data point, but that only works if the user wants to only like 10 data points. I need to be able to say, start at 0 and 1 to 900. I know how to do this in matlab, but I can't understand it in labview.

  Thanks in advance for any advice.

  It's still there. Even back in LabVIEW 7.1, the range of functions had a search capability. Have you tried it?

  7.1 if you want as the inputs to be the stage of start-up/stop/then you can do something like this (the ramp model VI icon will be different for 7.1):

  

• Pass the array to the formula node Eval (any chance to avoid this?)

  Hello

  I have not installed on my PC of MATLAB.

  I need to be able to say from the entry Panel custom formula "y = sin(Fm*2*pi*t[i]) + 2 * sin(3*Fm*2*pi*t[i]) + 3 * sin(4*Fm*2*pi*t[i])..."

  This form may contain a variable of harmonics (sine or cosine functions), but strict number of input parameters: Fm, t [i].

  FM - is a frequency.

  [i] t - is a time (ramp model) which is a table

  Can I pass array as a parameter of t [i] entry in formula node? How to do what other parameters, which are constants?

  Is there another method how to implement this - using the variable functions count?

  You are still far too complicated and it's still not scalable for a variable number of terms. You must be able to get out of math based text and think in terms of real LabVIEW.

  Here's a quick example using the terms in your first post (I show only a picture, because I have more LabVIEW 7.1).

  Modify if needed.

  

  NOTE:

  If you have more than a couple of terms generally, I tenacious feel that it would be simpler to configure a table complex stick (with the desired amplitude and frequency positions) and do an inverse FFT on this.

• Start, stop, step chart generator

  I would like to get into the start, stop and frequency step to build a table that will contain the value of to feed to a sweep generator.

  I have something that works, except for one thing; the timeout value. I can't get this thing to stop on the stop frequency value. The step value seems to affect it too much. So could someone take a look at my vi and help me with this? In addition, the code seems a bit complex for what might seem like a simple thing to do.

  Anyway, here's a slightly simpler implementation of your code. As you can see, you the codes was much more complicated than necessary!

  Below is the implementation of the model of ramp (recommended). Both give the same result for entries healthy of mind.

  I would certainly use the ramp model, because it has the better error handling (for example if the delta is zero or maximum is + Inf, etc.).

  You can view the code to learn something.

  

  You will need to pay attention to possible accumulations of bit errors, especially with fractional steps that cannot be fully represented in binary (e.g. 0.1)

• For loop that controls generator from RG

  This might be a stupid question which is easy to do in C++.

  I searched for 20 pages and could not figure out how to solve.

  Basically, we want to leave at some point (200 MHz), take 10 MHz at a time, put an end to some point (300 MHz).

  Firstly it output a signal of 200 MHz for 10 (variable) seconds, show a signal of 210 MHz for 10 seconds, then exit a signal of 220 MHz for 10 seconds, blablabla.

  So we need a variable that initialize at the beginning, add 'step' to each iteration.

  However, I can't find a variable (which can store the value) in LabView which can help me to do so.

  The table in LabView can store the value, but it is quite difficult to use the table.

  The C++ function (somehow) looks like this.

  CIN > startpoint > stage > end point;

  CIN > duration;

  a = start;

  b = step;

  c = endpoint;

  d = duration;

  for (i = 0; i< (c-a)/b;="">

  {

  RFoutput (a);

  Wait (d);

  a = a + step;

  }

  Is anyway use LabView to realize this?

  This might seem stupid, but I'm stuck for a long time!

  Thank you very much!

  If you think that the paintings are difficult to use, you need to start with some tutorials of LabVIEW base before making a simple program.

  In any case, look in the shift registers to keep state between iterations of the loop. You can also create a ramp of table covering your values and your autoindex then a boudanriy of loop FOR. There is even a function called 'ramp model.

• Create signals that are customized by using the spreadsheet of settings.

  Hello

  I'm quite new to LabVIEW but I have a complicated program to create. This framework requires a waveform from a spreadsheet of settings, attached.

  I have attached a chart of the appearance of the waveform. As you can see the different parameters related to durations and amplitudes of the wave as well as the frequency and the amplitude of the sine wave in the middle.

  In addition to this the program must travel creating each waveform in succession that the values in the change of worksheet for each different test.

  I managed to read the file in spreadsheet, make a chart from this and then I tried index table online to send to a loop for which would go through each test, but I don't know how to create the waveform of these values. I have tried to use the labView signal generators to create individual sections of the wave but struggled.

  Thanks for any help.

  Combine the GERD and my suggestions.  I had not used the Signal generation pallet front screw, but they manage most of the "math" for you.  The key step, you have to decide is what interval to use for "dt", "quantum" time, usually the same as the sampling interval.  Looking at your picture of waveform, you have a pulse, a ramp, a series of sinusoids, another ramp and a final push.  When you look at an individual Palette, it has parameters "dimensionless" you need to adjust to your particular situation.

  Consider the ramp time T3, starting at V1 and ends at V3.  Assume that your sampling interval is "dt".  You samples, end, thread and start entries in the ramp model based on the samples as follows:

  • samples = T3 / dt
  • end = V3
  • Start = V1

  Since you continue where you left it, I think that you do not want to "exclude the end?" thread true (to avoid double points), but I could be wrong on this matter.

  To the sinusoid, you have need samples, amplitude, phase and cycles.  Samples is again the total length of the sinusoid divided by dt.  The amplitude is one, phase is 180 (notice that your sinusoid starts negative), and cycles is however several cycles you want during the period of the sinusoid.  This sine wave, however, will be about 0, so you will need to add the offset constant V3 on the table.

  After having assembled all the pieces of this wave form complex and are concatenated berries resulting from it, have to turn them into a proper waveform.  Drop a wave function of building on the block diagram, drag to the top of its upper part a 'click' to expose dt and wire in dt and your table (Y).  You now have a good waveform.

• Strange behavior of the WHILE loop

  Dear experts LabVIEW

  I would ask you to give me an explanation of the behavior of the very simple VI as an attachment. This VI contains a WHILE loop with three parameters, input and STEP. The table of RESULTS shows the calculated values. Considering the input parameters OF = 0 TO = 1 LEVEL = 0.1, then the RESULTS table contains the values 0, 0.1, 0.2,..., 0.9, 1. Considering the input settings ON = 1, TO = 2, STEP = 0.1, then RESULT table contains values 1, 1.1, 1.2,..., 1.8, 1.9. The question is, why the number 2 is missing?  (I also tried to use different types of data, but without success). Thanks for your thoughts.

  Juraj

  Because you compare floating point numbers.

  For example, 0.1 cannot be represented in exactly in binary, cela repetitive additions probably will not end in an exact integer later.

  Since the three entries, you can calculate the number of values exactly and use a loop FOR. Do not use the convoluted code...

  Why not just use ramp model?

• Get the context of the sequence of other connectors (active) in the batch processing model

  TestStand 2014 - model updated the batch

  LV2014

  System controls an environmental Chamber and doing trials on 4 of the UUT.  Room Enviromental is the shared resource and is controlled by the synchronization of thread only lot.  A UI TempMonitor of Labview (also synchronized lot) pops up, until you reach the target temperature and soaking time is over (so you can monitor returns to the House and see the amount of time remaining.  It all works fine in the system of warnings in.

  Now, there is a new requirement to take permanently UUT s to ensure that they remain in the State during the temperature ramp and soak period.  The simple answer is to integrate this track in TempMonitor UI because it has access to all relevant data pads.  However, I would need to do an end run around traditional return since it is only run by one of the four (up to).

  My thought is that if I had access to all active sockets sequence contexts, I could ask them their index and State, follow up and write the results to réécrirait a local variable before leaving the user interface.  The only thing that prevents me from going forward, it's that I don't know how to get the engine to give me the sequence for each Active socket contexts (0-3 which may be disabled via the setting ContinueTesting false instead of disable flag, it is a product of use pass 3rd batch of party model, so the executions of people with disabilities are marked as completed when running rather than wait).

  Or, Alternatively, how inspect all executions and to determine what decision he belongs (if necessary, because my data acquisition engine runs in its own, hidden, execution).

  Thanks for any help,

  Mike Webster

  Actually, I was looking for a way to get the SequenceContext for the other active sockets that launched the TempMonitor GUI, so I could put results in the other sockets directly.

  However, I gave it, and instead I am launch the GUI TempMonitor in its own thread and have each socket to monitor the status of USE on its own with a separate VI until what the ramp / soak temperature is how the GUI will highlight Boolean StationGlobal that triggers the individual to continue.  More complicated, but also in the spirit of TestStand to things, I think.

• How to model generic spices work in multisim?

  I have a model external Spice, I need to use occasionally.  I alsways have trouble with that.  It doesn't seem to be because I don't understand the models or how operation spices, but more than the conventions to set and get properly hanging nodes and other aspects of MS are ambiguous to me.

  This is a model of NTC thermistor and a multisim schematic, I'm working on.  I tried many things but you do not have the errors go away.  I put back the way I started here.

  This model is:

  http://www.ecircuitcenter.com/circuits/therm_model1/therm_model1.htm

  Can someone explain how to get this model of thermistor NTC to work in MS?

  The ramp from 100V to 1V/s source matches the entry of temperature to the model.  (0-100 C, 1 ° c/sec on the grapher, if I ever get there)

  Thank you

  Hi David,

  I think that you pasted the netlist any data on the Web page in the Multisim Components Wizard. I think that it is the root of the problem. You just enter in the wizard components are really, the following lines:

  . SUBCKT NTC_10K_1   1  2  4  5
  ETHERM	1-3	 VALUE = {I (VSENSE) * 10 K * EXP (3548 / (V (4,5) + 273) - 3548 /(25+273))}
  VSENSE	3	2	DC	0
  . ENDS
  

  The remaining lines that are given to you generate the stimulus, as the voltage source that you placed in your schema.

  I have corrected it and attached the circuit has been fixed. Open this in Multisim and simulate a click > analysis > DC Sweep and click on simulation. You should see the curve IV of resistance NTC operating at different temperatures.

  Hope that helps.

• Ramping blamed the parameter in the profile of Stimulus Editor.

  Hello

  I am trying to familiarize themselves with the new Stimulus profile editor and encounter a problem I don't know how to solve.

  I have a model-driven setting. In one of my unit tests that I want to make a mistake on this parameter and the fault should scale the value exactly as the ramp function.

  I can do this within the profile of Stimulus editor himself or how can I do?

  / Johan

  You can do this with a custom real-time sequence. The easiest way would be to make a copy of the sequence of integrated ramp and modify it slightly to a fault of the parameter output instead of a simple assignment. You can open this sequence simply by double clicking it in the palette in sequences. If you open the sequence in real time of the ramp in the standard library, you will see the line where he attributes the current value of the ramp to the output parameter:

  RampOut = (I * Increment) + InitialValue

  All you have to do to change this from a standard to a fault assignment as assignment follows:

  fault (RampOut, (I * Increment) + InitialValue)

  Note there is a bug in the VM of real-time sequence that could not completely error a channel of the system unless another channel is currently failing. The easy solution is to create a dummy user and fault channels it in Manager fault channel of dialogue for the duration of your test.
