self test

[Anu]

is it possible to do self test of PXI Modules using programmatically in Labview as same as feature available in MAX

[Evan R]

Hi Anu,

The self test in MAX performs differently depending on which device is performing it.

Please tell me which devices you have in the chassis?

We are using PXI 8187 Controller,PXI Modules - RFSG 5670,RFSA 5660 and PXI 4461 have to self tested using LabVIEW Program,is it possible testing all feature available in MAX

Hi Anu,

In LabVIEW, there are self-test VI's for the NI-RFSG, NI-DSA board, and NI-SCOPE (the digitizer portion of the 5600) that you have. They are located in the respsective function palettes. There is currently no LabVIEW native self-test for the RF downconverter, however I'm looking deeper into this to see if there is a way to get the result of a self test using other VIs available in LabVIEW.

Please stay tuned, and I will be in touch as soon as possible.

Dear Evan R

i need clarification regarding Modulation depth,to measure AM modulation depth -We followed procedure as acquired RF signal is demodulated and then using Extract Single Tone Measurement.VI, calculated detected amplitude gives Modulation depth,

Now we want to measure positive and negative modulation depth which is available in standalone instruments,but we have issue in implementing in LabVIEW, please let us Know the Procedure for this calculation

[Evan R]

Hi Anu,

As for the self test on the 5660, there is no such availability to replicate what is happening in MAX.

To answer your question regarding modulation depth for AM signals:

Please refer to the example "ni5660 Demodulate AM.vi", or "MT RFSA Demodulate AM.vi", as the modulation depth is calculated in both of those examples. This calculation is being performed by simply multiplying the detected  amplitude  by 100 to give a percentage. These examples are available by searching the NI Example finder from within LabVIEW for "AM".

Best Regards,

Evan R.

HI Evan

In previous reply regarding self test - you told that self test vi's are available for NI-DSA board also,but i'm not able to find which VI to use for Self testing DSA,since there is no direct self test vi for DSA,only DSA calibrate vi is availabe.Is there any other way to do self test on NI-DSA board

[Evan R]

Hi Again, There is a VI entitled: "NIDSA Self Test.vi". I have included a .JPG to illustrate its' location. Best Regards, Evan R. Applications Engineer National Instruments http://www.ni.com/support

Hi Evan,

We don't have NIDSA palette in Instrument driver sub palette,We are using Device Deriver 7.4 version,in which version it will be available and specify complete software version requirement.is there any other way to find NIDSA self test

Thank you

Hi Anu,

The solution is to install NI-DSA.

NI-DSA Version 1.2 for Windows 2000/95/98/NT/XP
