[ -3 dB at 120 MHz with a RTB2004 at 70MHz bandwidth ?
did you measure correctly ? ![Wink ;)](https://www.eevblog.com/forum/Smileys/default/xwink.gif.pagespeed.ic.cldandycH0.png)
I am sure that I have measured correctly. And it is not unusual that the bandwidth is higher than the manufacturer says.
Why is the update important ?
Is something not working correctly ?
There are some small errors, but they are annoying. e.g. in the LAN settings, changes in the ports are ignored. For me it is also bad that triggering on a PAL video does not work properly. The external trigger is also limited for this.
But a bad error is in the normal trigger mode, where the sample rate and memory depth is displayed or used incorrectly. The documentation in the manuals for the SCPI commands is sometimes incorrect or missing.
I am a bit disappointed about the quality for the price. Also I could never reach anybody at R&S by e-mail. I have given up collecting the errors and passing them on. As a company you probably find it easier to be heard.
this is of course annoying with the bugs.
Someone who is not so well versed may not even notice the trigger errors and look for the cause elsewhere.
But bugs are everywhere, also at Siglent, Rigol, Tek, Keysigth, PeakTech,...
Maybe it was different in the past, when firmware updates were not yet possible. Probably there was a better final check.
My old analog Hameg Scope has, I think, no bugs. At least I haven't found any in the last 25 years ;-)
