error 20309

[samtyms]

Hello,

I received this kind of error :Error -20309 occurred at Amplitude and Level Measurements->practice.vi
 (waveform index 0 of 1). Possible reason(s): Analysis:  The amplitude of the waveform is zero, so the histogram method cannot be used.

I'm connecting the amplitude and level measurements to  a waveform chart. and i received this kind of error. Please help to solve this kind of problem.

Thank you

We need to see code to help you debug this.

When you attach code, attach the VI itself.  We need to be able to open your code in LabVIEW and try it out.

hey guys please help me to get out of this error

i searched @ this but didnt get any clue.

please

Hi guy,

the amplitude of the waveform is zero and so the histogram function cannot work as expected.

Solution: set an amplitude larger than zero…

(As long as you don't provide your VI you will not get much more help. Remember: we cannot edit or run images using LabVIEW!)

hey GerdW , 

i have attached vi and i have set amplitude 1

A full period of a 2 Hz signal is 500 msec. In the "Configure Simulate Signal", you specified 100 samples at 1000 samples per second. That's only 100 msec of data. There is not enough data to analyze the waveform.

As a minimum set (Num Samples) / (Samples per sec) to be greater that 500 milliseconds

Hi

Please help me, with the same error

Hi osirism,

you are using way too much ExpressVIs! (And lots of other bad coding style.)

See the attachment for (only) some improvements!

You should also rethink about your DAQAssistent usage: you set your AI reading to just "1 sample on demand", but still convert the DDT wire to an array! Why is that? You only get a single (scalar) sample value!

On your error:

did you read the error explanation? Then it becomes pretty clear how to solve your problem…
