Hello everyone!
Could anyone tell me whether the white noise can be made by the signal generator function of PCSU200 or not?
Because in the PC Lab200 software, I cannot find any wave seem like white noise.
If I would like to make white noise by this signal generator, how to make it?
Thank you!
Yes, there is no noise generation option in the PCSU200.
One option is to use a library file.
The library files of the PCSU200 are quite short, only 512 samples.
So if there is put some noise “image” to the file, the output is not real random continuous noise but repeated sequence of noise (pseudo noise).
Thank you for your help.
We have another problem here.
We used the pocket audio generator K8065 to output the sine wave (1kHz,0.68Vrms).
Then we connected it with a small speaker (8Ω, 0.2W).
The speaker gave us a sound.
After that we use the PC Lab200 software to generate a same sine wave (1kHz,0.68Vrms).
Then we connected the same speaker to the output of PCSU200.
The speaker gave us a very different sound.
And we used the oscilloscope function to check both of them.
They had the same waveform and same parameters.
So could you tell us why the same waveform and parameters gave us two different kinds of sound?
Thank you!
The outputs of the generators are different:
K8065: Output level (10Kohm): 0 to 775mV
PCSU200: Output impedance: 50ohm
The signal of the K8065 may be more attenuated when the 8Ω speaker is connected to the output.
Did you check the waveforms when the speaker is connected?
