As an old geezer trying to make the transition from analog to digital scopes, (and struggling). Is there a way to display the volts per division permanently on the screen of my 802X?

In "Display" menu, slide the right menu up, and you will find there a "Axis labels settings".
Click on that and switch axis labels On, set them to Moving, and select left right or middle for vertical labels.

This will show calculated scales on graticules for currently selected channel.

Is the SDS800X able to provide 5V at 2A out of the USB ports?  I would like to use a little travel router with the oscilloscope.
I use this AP set to Bridge mode all the time:

5V 1A

Look up the power requirement spec for yours.

That’s useful to know because the router I am looking at using is very similar, so I am pretty sure it will work. Thanks tautech.

I don’t want to use a wall adapter because this is meant to be a portable setup.

I recommend this. power consumption <1W. IMO ideal for portable setup.

Thank You very much. It feels more familiar.

Apologies if this is an obvious question that was addressed elsewhere, but what setup did you use for the bandwidth measurements? The closest I can do to approximate the FFT displays you presented was to feed a broadband noise signal into the scope and then run an FFT with averaging.  I'm not questioning the bandwidth figures (I pretty much had similar results), but am stymied on how you produced them.

Most of the settings are visible in images posted.
Use peak hold mode for FFT and sweep frequency by signal generator.

Thanks, peak hold on the FFT answers my question as to how the graph was so smooth without averaging. However, how do you synchronize the generator frequency sweep with the FFT sweep?  To me that implies something like a tracking generator on a SA, but not sure how you would duplicate on the SDS800X without some additional equipment.

Scratch that.  I'm guessing (can't test it right now) that the answer lies in the peak hold...  Thanks.

You don't synchronise. You let the generator sweep very slowly so that the scope captures a large number of records during the sweep and combines them with peak hold. Don't use a too long record length (and number of FFT points) for this use case.

I use these settings when I want to determine the bandwidth using sweep and fft peakhold:

Thanks, Martin (& gf).  I ended up with the same setup after thinking a bit more about how max-hold operates  :palm:
