@Herbertl:

First: welcome to the forum.

Second: As long as you cannot come along with something similiar like

https://www.eevblog.com/forum/testgear/rohde-schwarz-rtm3000-review/msg1604185/#msg1604185

then you can't be taken serious. Not for all the rudeness which comes from you with no substance (apart from the fact that you are able to use youtube).

Or, let me put it this way: If I should have a question about oscilloscopes or if I need some advice,
nctnico would be surely on top of my list of the persons to ask for.

Just my two Cents.

BU508A

Exactly.
I certainly don't agree with nctnico on many topics. Had an argument or two with him too..
He also made many points that I absolutely agree with..
Such is the fact we are all different.

On topic of scopes, among other posts, he made great (and quite realistic) review od that RTM3000 and is skilled engineer.
I don't think he deserves that tone..

Regards.
Sinisa

next video, next bug.

nctnico · « **Reply #152 on:** May 05, 2019, 09:47:49 pm »

Again with old firmware!

I can't reproduce any of the bugs shown on the RTM3004 I have here.

Maybe someone needs to let the guy know he can update the firmware. In modern times we have that luxury(curse).

Fresh out of the box ... Firmware 01.501

https://www.rohde-schwarz.com/de/firmware/rtm3000/

Lets take a look

Extract from the Release Notes

New math functions track: Period, frequency, pulse with and duty cycle
Second cursor source implemented.
New pattern types in option RTM-B6 pattern generator: PWM, PWM - RGB LED and PWM -Test Signals.
Symmetry attribute in signal function 'Triangle' with option RTM-B6 function generator

Low pass and high pass function in math improved.
Acquisition mode High Resolution in memory mode Auto improved. Higher sampling ratesavailable.
For measurements SCPI commands response significantly improved.

And other things and fixes

Thanks

i assume this is for a measurement trend trace? finally

JoHr · « **Reply #157 on:** May 15, 2019, 10:03:07 am »

Just tried the internal test-apps with signal
As far as i can see it is the trend over one acquisition, not multiple ones

Hi guys
Hope your had a good time. I spent 2 wonderful weeks in Italy

and almost missed a new video.

How are your scopes doing decoding?

Herbertl · « **Reply #159 on:** June 08, 2019, 11:01:15 pm »

What a poor performance. Very disappointing.

Does R&S do any quality checks? It does not seem so.

Indeed. Posting videos using old firmware and not putting a note in the video the problem has been fixed.

I think this goes to show that doing a thourough review on a relatively new instrument is very likely to result in having to redo some part of the tests due to a firmware update. In my experience it is better to wait with a review (or halt it) until new firmware is released. Otherwise the review is outdated before it is published.

Herbertl · « **Reply #161 on:** June 09, 2019, 02:48:40 pm »

What firmware fix do you refer to?
I usually believe what I see and the release notes on Rohde & Schwarz website they say it is not fixed.

What counts for me as customer is not a single bug, but the high number of bugs.

The scope came out in January 2018 for 20k.
imho it is not what you expect from such a scope and it is not nice at all to sell it with so many bugs.
And I really cannot figure out a reason why you defend that.
In my view, the only old thing are your excuses.

Have a nice sunny day.

The release notes say the autoset mode is fixed. To verify I tried to reproduce the effect shown in the video and I can't reproduce it using version 1.5. You also have to keep in mind that release notes typically only contain major fixes and not the minor fixes so only by testing you can determine the full extend of a new firmware release. So if something on the (in this case) autoset mode has been fixed you can assume they fixed all the bugs concerning autoset.

And for sure you are right there are a large number of issues in the RTM3004 but many of the bugs are not so severe that they are making the RTM3004 useless. Most of the bugs are user interface issues which are easy to work around so not a high priority. To me it seems R&S has primarily focussed on getting the core functionality working right instead of ironing out all the wrinkles in the user interface.

Releasing equipment with bugs seems to be standard these days so if you want a relatively bug-free piece of A-brand equipment then you have to wait for about a year after release.

Why all the visceral hate from Herbertl?
Burned customer or competitor maybe?

Fred27 · « **Reply #164 on:** June 09, 2019, 04:59:41 pm »

It is a bit weird going to such effort to try to try to make the RTM3000 look bad. He got banned from Element14 for joining up just to post the same stuff.

there is a more orless useless RTM300x-bashing thread on https://www.mikrocontroller.net/topic/473278. I assume Herbert wanted to bring this "truth" to this forum too.

BU508A · « **Reply #166 on:** June 11, 2019, 09:11:45 am »

Imho he is simply a troll with no clue.
Guess, this is one of the sad things you have to live with it in internet forums these days.

Herbertl · « **Reply #167 on:** June 12, 2019, 02:05:15 pm »

NCTNico and Fred27, you reviewed RS scopes and many trusted you.
Is that confidence justified?

Now it turned out your reviews are gappy.
You did NOT find any bug,
though there are plenty of them.

That must be hard for you and it is obvious that you are sulky.

Who will trust your reviews any longer?
Me? Surely not! Burned once, burned forever.

imho you just cannot bear the truth.

I did not offend you. But you felt offended because you know I am right.
Now you are offending me. It is not the other way round.
I don´t care. I know what is right and wrong. So do what you want.

Hello,

the reviews from nctnico are very good and informative.
He knows from what he writes.

Best regards

That is a lie. Quote from my review ( https://www.eevblog.com/forum/testgear/rohde-schwarz-rtm3000-review/ ):
Issues
Issues found so far:
- Averaged trace disappears when changing time base in stop mode
- Infinite persistence trace disappears when the cursors are enabled/disabled.
- Persistence fading doesn't stop in stop mode
- Power analysis shows wrong numbers in switching losses.
- The back button in the history menu doesn't always respond
- Segmented mode segment accumulation only works after pressing 'play' button.

I would like to see a shorter list here and some things like the averaged trace disappearing really need to be fixed but all in all the list isn't that long given the number of features the RTM3000 has.

And if you would have read my review more careful then you'd notice I spotted a few other issues as well which R&S fixed (and I re-tested) before publishing the review.

ogden · « **Reply #171 on:** June 12, 2019, 06:25:52 pm »

I better see review that shows various product functions I actually plan to use rather than watch pointless 12 minutes of repeated AutoSet button press that demonstrates random results of bug which supposedly is long fixed in latest firmware version

It is worth to mention that "test" posted in June 8 2019 is dated November 2018 (video screenshot @0:11):

KaneTW · « **Reply #172 on:** June 12, 2019, 08:06:34 pm »

I've read through that mikrocontroller.net thread and it really just seems like a handful of sockpuppet accounts jerking off over inconsequential bugs.

No one cares if you are offended. That's not an argument. On a technical forum we argue with facts, not feelings.

...

I know what is right and wrong.

Then you should think about if it´s OK to remain complaining things that are already done or fixed.

Sure for you it has been wasted time to make a review which is not valid for found bugs anymore on final release date.
But that is life.

If you look at all the reviews that have been done there are plenty of major and minor issues that have been found from people.
And I wont cover the RTM3000 only. RTB2000 is a member of the same family.
--------------------------------------

Based on a foundation of repetitive signals you might have seen that the Autoset works also for FFT-Mode ...
Setting up a first frequency range pending on signal frequency.
That´s a cool feature to be told in a review.
