agilent u2761A generate aribrary waveform

[rajeswari]

Hello Team,

We are using U2761A agilent function generator for generating different kind of signals. We couldn’t find how to generate Impulse signals using  Agilent measurement manager and want to implement the same feature using labview application.Our requirement is to generate Impulse signals which are of 3 KHz two consecutive sine wave

Sample signal to be generated is attached to this post.

The signal will consist of high-energy impulses that vary in period as shown below , we have 10 different speed codes...for eg: 

Speed Code	Period (ms)
HS	no code
0	224.3
VD	236.2

We need to generate similar kind of signals for +ve deviation, -ve deviation and no deviation for 1% of the period(ms) mentioned. So (3*10 =30) signals of these types to be generated.

Could you please let us know how can we approach using Labview and the best approach to be followed.

Thanks In Advance.

Hello,

The way in which you can communicate with your device will be via the VISA. Now I guess the U2761A is a usb device so you will be plugging the device and using something called Instrument Drivers which are ready made API's for certain instruments. These are readily available at ni.com or you can access them from your LabVIEW as well by going to Help>> Find instrument Drivers and searching for your instruments. I tried attaching the instruments drivers but it is not getting uploaded but you can search for the same in the way I mentioned. Also if you are having issues in still generating the signal I would recommend you to try NI hardware for doing so.

Hope this helps.

Thank You.

Hello,

I am using the Labview instrument drivers provided to talk with Agilent U2761A. I am able to generate beacon and modulated signals also using those drivers but my concern is to generate impulse signals as i mentioned in the earlier message by having some programmable intervals like burst signal which i couldn't find out in the available drivers.

Your best approach is to first try to create the waveform manually. You may want to contact Agilent as this problem would seem to be more instrument specific and not software, in my opinion.

p.s. In the future, if you have new questions, post to the instrument control board as this one is for NI Signal Generators.

Thank you Dennis. I contacted Agilent and they told they didn't provide burst feature for this device and I need to generate aribitrary signals to generate these kind of signals.

Is there any way in labview which I can generate 3KHz signal with a programmable interval of 340ms and followed by one more 3KHz signal and save it to an excel file so that I can copy this file to Generate simulated signal express vi and pass to my actual device.

Any sample application will be appreciated.

Thanks In Advance.

Look on the Waveform Generation and Signal Generation palettes. What is created is nothing more than arrays in that you can modify in any way that you want. don't understand why you would use one of these functions and then use the Express VI. If you use the built-in functions, you can use those to directly pass the waveform to the function in the driver.
