Hello, Basically it was all in the initial message, but in general I'm doing an output analysis of a filter. I thought that I can do it easily with White noise. One of the critical parameter is an exact input level and that requirement is met when sweep-method is being used (rather than White noise-...
Thanks for the reply. This sounds like an explanation. However I need to know an exact amplitude so white noise is not an option in this case then. It is ok since preferable methods is available.
Hello. Could you help me to understand FFT and Spectrum analyzer. See below some issues I can't understand. Environment: [See attached image Environment] Setup: Generator set to white noise which is about 800mV RMS. So far so good. [Image Setup] A jumper from signal generator output to Channel 2 inp...
Hello, Anyone actually using USB Isolator? I just built ADu4160 based isolator. PS 2207 is recognized by Windows but not by PS6.
If someone is using an isolator, please share the information of which isolator works with PS.
Well... you are giving me an explanation why this happens. But for me this is a failure situation. If I feed a pure 5 Vpp sine signal to PS and on screen I see less than 1 Vpp signal, it is a failure. I changed collection time to show only 5 waves but No. Samples is also reduced to 1000. Amplitude t...
I think it is better if you specify what debug data you need to investigate this issue. I don't know if I understand your question right but according to the properties window no. of samples is 2000. (Sample rate 1GS/s). "Number of samples" setting is 100kS, but it does not influence on this issue. ...
Well, you are talking about cleaning up noisy signal which affects to amplitude. You are true naturally, but still it is NOT the issue I'm, talking about. Maybe you get the idea by examples. First picture is 8-bit signal from an external signal generator 5 Vpp. PS measurement says 5.1 Vpp which is q...
Well, I don't think you answered to my question. The situation was very simple at the beginning: I tried to use Resolution enhancement and made a simple sweep test. After the frequency started to increase, amplitude started to variate between 10% and 100%. It can't be proper behavior! Or if it is, I...
Please check Match channel range setting-issue too. Checkbox "Override automatic range selection" does not work properly and when you want to change range, you need to change min/max values of math channel. If you deselect the checkbox, it will be reverted back to default settings.
Hello. Sure, no problem.
This is easily repeatable.
1,001MHz signal from external source, changed to 2,001MHz and waited about 20 secs and then saved attached psdata.
Here's couple of more images. The first one is taken few minutes after frequency change and the second one 30 mins after that.
Should you need more information please do not hesitate to contact.
