USRP N200, GPSDO toolkit, scale and 'Phase '!
I need to run a simple experiment using two USRP N200 auxiliary with labview program to receive the magnitude and the phase of the received signal? Is this possible? and what is this phase value reception reliable because I checked the value of quantity calulating it manually which is OK!
Also what someone incorpated GPSDO toolkit with USRPs? which helps with USRP two synchronous? It would be a great help if someone has the labview VI to check to make sure the GPSDO Toolbox works well with USRP or not?
David is currently out of the office, then I wanted to touch base with you on your question about flashing your N200.
I would like to talk with Ettus thereon, since you are flashing their FPGA. They may have some utilities that you can use instead, and an overview on why you see this information in the Flash utility.

I used 2 USRP in reception. They are connected together via a cable Mimo.
I want to locate the source of the issuer. So I need to synchronize the two receivers.
I did the constellation to the two USRP:
1 - with identical cables 2 - with different cables.
(figure: attached files)
I have synced my receivers (in time and phase)?
Please help me
I have a media player allowing a SMP-N200 with DLNA function and a speaker of a SA-NS400 wi - fi connection. While I can listen to the files audio of my DLNA server and even Internet streaming Pandora to my speakers using the select button on my controller (Sony media on Andoroid), I can't stream audio from Netflix to this same pregnant movies. The remote speaker sounds better than my audio system of TV and I would like to listen to audio from sources to my SA-NS400 of streaming on the Internet.
Hello Jaime and welcome to the Discussion Forum for the users.
Thank you for the SA-NS400 wireless speaker. Please take a look on the link below to understand how much streaming is and what to do with it.
I try to add two Phasers of tension and to get incorrect when simulated results on Multisim using the frequency unique AC analysis. I changed the amplitudes of analysis AC from both sources to their respective values of 20 and 15 volts. The result of the addition should be size = 25 volts peak and phase = 66.87 degrees, which does not match results of Multisim. What I am doing wrong?
Thank you in advance.
You must click twice on the fickle source V1 and V2 and the "AC size' and the 'magnitude of AC Phase', change the settings.
Also, depending on your preference, select Options of Simulation global preference, time = 0 if you want the right to shift to change phase or left, you can configure it here. This setting affects your calculation of phase.
Hi, does anyone know how to find the RMS or amplitude and phase to the fundamental frequency of a signal measured in Labview?
I tried with the Analyzer for harmonics of buit - in, but he can't give the values of the phase angle. I also tried the FFT VI spectrum, but I don't think the results are good.
Harmonic distortion Analyzer is a polymorphic VI, this means that if you connect a single signal in and then you get a unique signal, and if you connect a table of signals in out you a table.
The VI I is not polymorphic, but you can easily change to work with multiple signals. If you look at the standard implementation for the harmonic distortion Analyzer N-channel then, he simply called the channel 1 harmonic distortion Analyzer a loop for. So you can easily call my VI in the same way. See attached screenshot:

I am trying to simulate the loop gain and phase for an oscillator in multisim. I use the Middlebrook method and can get the gain in current and the gain in voltage by using the function "add the words" in the analysis. Then, I need to use these winnings to calculate the loop gain and phase using the equation T = ((Ti*Tv)-1) /(Ti+Tv+2), where Ti and Tv are respectively the current and voltage gains. I have been unable to bring the last expression and will appreciate any help.
Yes, the Middlebrook analysis technique can be implemented with Multisim. Please see the circuit below as an example on how to apply this method in Multisim.
Let me know if you have any questions.
I'm trying to measure the frequency and phase of a square wave from a data acquisition card using vi retrieves your unique information. So far, the frequency can be measured precisely, but there are a few problems with the measurement of phase.
I have attached a sample program here. I generate the wave square using Square Wave PtByPt vi. The default sample size is 1000. When I put the frequency = 7.43, phase = 80, the frequency can be measured precisely, but the phase is completely. Is there something wrong with my program?
Thank you very much for your help.
A square wave is not a single signal ;-)
If you have a square wave use the edges to make measurements.
I need to print a Wallcovering that will be about 17 m long. I've created several images more small (about 4 m square) and they have narrowed it down so I could make a plan for how they will join together to create a single image. But I'm unable to identify ways to print at the right scale. My plan is to do the last piece that I send to the printer at the 10% level and then ask the printer to print to 1000% - which would be correct? In addition, the thickness of the line drawings in the 4 m, those are the right size I wish they were, but by reducing my images - the thickness of the line remains the same. How to do this? What is the best way to expand all?
Thank you very much
If the thickness of the line remains the same and you want to scale, double-click on the scale tool and turn on the features of the scale and effects, before scaling.
Yes, 1000% woful be correct for a 10 x scaling.
I'm working on a project and most of the images do not match the size of the screen so I used the video efects > scale and Position to do things. It changes, then I visited and then go back to it and he's back to where he started. I can't understand this?
Even by double clicking on the image and move it with the mouse do not work. It leaves a black line next to the image where it does not. How to cover, I'm doing it wrong? This is how I did in the past. I tried l ' down and restart. Nothing works!
Let me know if you figure out how to fix it you and how you did it.
I thought about it! I went through everything and I mean everything and it was the box that says unifirm scale under video effects. I want that my last 3 hours back Adobe! Thanks for the help though!
How can I scale and move a finished animation (with several object - should I consolidate them or something since I didn't wan't to touch the bottom?) without having to do it on each keyframe? I'm completely new flash a detailed response would be appreciated.
You must take the time to familiarize themselves with the tool you are trying to use the option - the forums are no place for lessons, mainly aid just for the problems that you can demonstrate.

I am trying to build a report that is real, budget, the previous year and forecast of dollar amounts for the current year by period. The requirement is that are real and projected bar graphs and graphical prior budget year and line. This part was simple, however, the two scales on the left and right axis are not aligned with each other so that it cause confusion between reports. I need to find a way to force the scale for lines on the right to be the same as the scale for the bars to the left, but I also need to make sure that the left updates dynamically based on the data scale.
Any ideas on how to force the same scales and always updated dynamically according to the data?
On what version work? In the last editions at least there is a button (icon is a blue star in the part of graphical configuration). 'S called it the advanced properties. There is a property, you can set: "line to synchronize and the axis of the bar."
I use 8 USRP RIO 2943Rs transmission of signal and receving (4 for Tx) and 4 for Rx I'm using the "signal-based" method for synchronization of all devices. And I did it. I tested the system the result is very interesting:
1. when I put the sampling rate of less than 40MS/s IQ, I can obversve very good phase locked Tx and Rx signals (I use a sine wave CW for tests), please refer to video joint (locked 40MSs)
2. BUT, when I put the IQ more than 60 MS/s sampling rate, I'll lose phase lock. Please refer to unlocked 60MSs. My goal is to run the system at 120MS/s
I have doubt as to if the problem comes from two sides:
a. the sync methed isn't fair
b. OR, should I increase the clock that operates the loop 'In Streaming radio engine' in the FPGA VI. as shown in the following image.
I would like to ask experts in the forum to discuss the solution of this problem.

I have a problem adding my custom code scale. I have a pressure sensor that works in the range of 4-20mA. So, I made a custom scale as you can see in the code and tried to connect the name of custom on the DAQ.mx scale. Which doesn't seem to work any suggestions?
Another problem I have is I want to be able to log on to the application with a Boolean button. How to do that if I want to keep the ability to write data only to a determined time interval?
How to make a graph of mixed signals as indicated in the attachment to only show whole on the y axis and reduce the grid to do the same thing?
programmatically, you have a property node for the scale that should do the job: 'increase '.
=> property node, Y scale, range, increment.
The grid will follow.
The minimum increment depends on the vertical size of the chart (and the size of police marker I suppose, who also has his property node)
example attached, hope it helps.
I am doing a project for pattern recognition and lead to a VI (Please find attached). There is something that I don't know and would like to ask:
1 VI works, but in a funny way: most of the time I have to pass the "Create Template/model search" button twice in order to get thin VI work (there were only a few times I just need to click once on the button). What is the problem here and how to fix it?
2. I understand that IMAQ game model works with RGB images. So is there anyway that I can always get pass images RGB by IMAQ learn boss, IMAQ Match, while the resulting 2 'Template' and 'Image' are always displayed in color mode.
3. are there in any case I can still detect the object if the scale becomes a problem (I need to go far from approaching the object)? To resolve this problem, I need to use IMAQ matches geometric pattern, which I learn from somewhere in the forum it took much more time to match my result comparing IMAQ Match jacquard?
Thank you very much.
