Re: [802.3_B10GAUTO] suggestion for comment i-4 (spectrum analyzer/balun vs. DSA)

Just to be clear, the issue was not the use of the spectrum analyzer it was concerning the BALUN.

 

There were comments that the BALUN was not defined and there was concern that the BALUN would give incorrect or inconsistent results of PSD measurement if not correctly designed for the complete frequency range.

 

It was then asked how this measurement was being made by most people and those that replied stated they make this measurement with the same setup as the transmitter test fixture 1 that required no BALUN and used a capturing device.

 

I volunteered to discuss with others to come up with a comment to eliminate use of the BALUN or define it.  The group decided to eliminate the BALUN and therefore the spectrum analyzer.  I was then volunteered by the group to submit the comment. 

 

We can discuss this in more detail during our comment resolution.

I would suggest that in addition to the proposed remedy, we change the label of the “Digital Scope / capturing device” in Figure 165-25 to “Measurement Equipment (e. g. , digital scope / capturing device)”. That would

I would suggest that in addition to the proposed remedy, we change the label of the “Digital Scope / capturing device” in Figure 165-25 to “Measurement Equipment (e.g., digital scope / capturing device)”.

 

That would suggest to the user a digital scope, but allow measurement with an appropriate spectrum analyzer, or other instrument for the PSD.
