runnig RFSG Pulsed Data.vi on PXI-5652

[nolsqn]

HI .

I am trying to run RFSG Pulsed Data.vi on pxi 5652 but i keep gettin the error "niRFSG Configure Generation Mode.vi<ERR>Invalid value for parameter or property."...how can i resolve it .......and my other question is that wether this card is capable of generating  arbitrary waveform......

I am new to this card although i did take  the hands on course available on the net but i am not familiar with all the block till now.

I also change the parameters in the VI but nothing work .

help needed

thnx

Hi,

The reason you are seeing this error is because this example is only compatible with the 567x devices.  Running this example with the 5652 will not work because it is not meant for this type of application. You need to have an arbitrary waveform to create the IQ signal and then an upconverter to convert the signal to RF.  I would recommend to review the manual and specifications for the 5652 to understand the full functionality of the device.  The 5652 is stated as being a continuous-wave RF signal generator signal generator with modulation capability.  Do you have any other modules in your system?

There are specific examples that are dedicated to just the 5652 but there are no examples of generating arbitrary waveforms.  We have specific function generators that are for that purpose.  The 5673 for example is comprised of 5450, 5611 and 5652.  The 5450 is what produces the I and Q signal to the Upconverter (5611).  The 5652 provides the LO signal to the 5611 which upconverts the IQ signal to RF.  

What other devices do you have in your system?  What is the overall application?  If you are just starting out and want to see the functionality of the 5652 I would recommend to check out the 5652 examples in the NI Example Finder (Help>>Find Examples, search 5652).

hi jordan

i have other than the 5652 also ..... 5660 and 5670 ....but the problem with 5670 is that when i run the example it gives an error to give a resourse name to AWG in MAX?? how i can solve this error

thnx

I am guessing that you need to associate the proper Signal Generator/AWG to the upconverter in MAX.  I attached a screenshot to show how to properly do this.  What you need to do is right click on the upconverter (5610) in MAX and select»properties.  You then will select the 5421 in your chassis to associate with the upconverter.  This needs to be done before you can run any examples.

If this is not the issue please let me know and provide some additional information or screenshots of the error.

hey sry i forgot to tell you that i have connected my chasis viz mixi card ....so when i click on the properties i dont seem to find the option for the assosiate cards ..... is there any other way to do it ?

It should be very similar to what I showed in the last screenshot.  However, it will be under either the MXI tab or the PXI chassis tab to find the device.  When using a controller it will show up either under devices and interfaces or a PXI chassis.  Just because it is a MXI connection does not mean that you dont have access to the specific devices.
