Good afternoon, now I’m working with SM200C.
In the spike of the latest version, when measuring the channel power for a stable signal and changing the type of window, the channel power also changes, it seems to me wrong.
It looks like this change is 10 * Math.Log10(windowBW).
Is this a bug in the spike? The same is observed when measuring through the API. Should I subtract the constant 10 * Math.Log10(windowBW) from all levels on the trace, as I do now?

Hi Jacks,
Unfortunately, I cannot reproduce the problem with the provided information. Would you be willing to email us at support@signalhound.com with more information about your issue? Please provide screen shots of the Spike software and descriptions of your setup and any signals you are generating/measuring. Hopefully we will be able to quickly troubleshoot and resolve your issue.
We look forward to your response.
Andrew
AndrewModeratorFor future reference, when making channel power measurements, both ‘average’ detector must be selected, as well as ‘power’ video units. If either of these settings are not used, you will not get consistent channel power measurements.
