myRIO input analog signal measurement

[constantinex]

Hi everyone,

I want to know that how to measurement the input analog signal from a signal generator to the input pin of myRIO. Is it like using myDAQ to measurement? or need to use other Labview function panel? For example, how to trigger the input signal on Labview?

If someone know this, please give me an answer.

Cheers,

Johnson

Hi Johnson,

The minimum software required to program the NI myRIO processor with LabVIEW is the following:

• LabVIEW
• LabVIEW Real-Time Module
• LabVIEW myRIO Toolkit

All of this software is included in an Academic Site License. Additionally, the full myRIO Software Bundle can be downloaded from ni.com and activated with a valid serial number.

You can write programs quickly using I/O-specific Express VIs directly from the LabVIEW palette, which includes an "Analog In" function which you can use for your signal generator input:

hi FouadR,

Thanks for your answer. You mean that using the 'analog input' function panel directly and connect the measurement parts on the block panel? what's the difference between '1 sample analog input' and 'n sample analog input'? Also if I want to trigger the input signal, how can I do that?

Hi Johnson,

1) "You mean that using the 'analog input' function panel directly and connect the measurement parts on the block panel?"

Yes, and you will, of course, need to connect the signal generator to an analog input port on your myRIO.

2) "what's the difference between '1 sample analog input' and 'n sample analog input'?"

N Sample Analog Input allows reading multiple samples for each analog input channel at one time. 1 Sample Analog Input allows only one to be read.

3) "Also if I want to trigger the input signal, how can I do that?"

You will need to monitor a digital input. When the input goes either high or low (choose one), you start data acquisition which is performed in a loop (e.g. while loop).
