Just to put some oil in the fire, here is the same signal, same Tek probe, but seen with 1.5GHz 8GS/s HP infinium. So compared to the rigol, we see a peak at the beginning of each pulse, where this peak is observed i.e. after the front. On rigol is at the end of the pulse - before the front. Any explanation? Bad interpolation?

The problem cannot be interpolation when there is nothing to interpolate.  1 GS/s on the Rigol is a point every nanosecond so unless the Rigol is mangling the original sample points, there should be no problem.

Even if it was mangling the points you'd only notice the mangling with more than two channels on. The difference would be close to zero at 1GS/s.

Are the buttons nice hard plastic, or are they rubbery and soft? I can't tell from pictures and reviews I've seen online.
Seems like an obscure piece of data, yet easy for anyone (who owns one) to provide.

Thanks,

Matthew

Are there any sub-$500 oscilloscopes that you know of which DO have hard, plastic, tactile, satisfying-to-press buttons?

Doubtful, since tactile buttons (in particular, the button caps themselves and the additional assembly cost) cost a lot more than rubber membrane buttons, so they’re kinda the first thing to go when cost-cutting...

Not all buttons need to be plastic nor do they want to be as it restricts the designers to not being able to use LED backlight to show certain modes are selected.
The flexible membrane buttons have proven to be very reliable in scopes.

I think you need get to a shop that has a few brands of scopes and have a play with a few in order to find one that gives you the physical feedback you seek.
Unusual request but ymmv.  :-//

You can have a look at scope which costs 1000, 2000, 3000, 4000 and beyond, you won´t find a scope without rubber keys and carbon contacts.
Last scopes I known were analog ones from the early 1990s, which used mechanical switches.

18000 USD Keysight MSOX3104T has rubber keypad...

$100k comms test sets have rubber keypads. There no longer seem to be any other types used in new equipment.

Of course you can make plastic buttons that illuminate. It just pushes the cost even higher! :P

It is funny how different industries do or don't adopt different cost saving measures. You never see, for example, home cinema receivers with rubber membrane buttons, they use tact switches, often with elaborate lighting on higher end gear.* Similarly, that industry still uses a lot of VFDs, even as most other areas of electronics has abandoned them in favor of LCD or OLED.

*They also often use the quality of buttons on remote controls as a product differentiator: cheap devices have remotes with rubber buttons, high end models have remotes with tactile switches. My Panasonic plasma TV, the top of the line of its model year, has a magnificently well made remote, with tact domes on a real PCB, then a rubber membrane, designed to gasket against liquid intrusion, and then plastic keycaps, each individually keyed to ensure each key fits only in the correct position. A friend of mine bought the entry level model of the same year, and it came with a simple rubber button remote with identical functionality.

Hi All,

Not sure is this is the best place to post this but, here goes.
I wanted let you guys know that I have made a Bode Plotter for the DS-1000Z scopes.
I knew that the DS1054Z could not create Bode plots, but that did not stop me wanting to create one.
So I started searching for viable solutions.

I first found Dave's YouTube clip showing a way you can sort of do it, but not quite.
See here
So I continued to search for more inspiration.

I then came across this python script https://github.com/jbtronics/DS1054_BodePlotter
Which shows a DS1054z Scope connected to a JDS6600 AWG.

So I thought maybe I can make my own. So I got to work writing my own Python script and a week or two later I finished it.
I works with a DS1000Z Series Scope connected to a DG4000 Series AWG.
I think the code could be easily modified to work with pretty much any AWG that has a LAN connection and supports scripting commands.

Here are some screen shots of a basic low pass filter.
I was blown away by the accuracy.

Hope you guy's like it.

Nice work. I've got a similar thing I was using with my DG1022Z and DS1054Z. I've not got an SDS1202X-E and a DG822 and haven't updated them yet  :(

The ability to "compose" instruments is a killer feature these days.

Looks intersting. Did you put your code on Github for the DG4000 series? If it is easy to modify, I might have a go at getting it going on the HP 33210A. My python is limited...

Navigational Warning

Don't flash the Z-E firmware in the old DS1000Z scope!

Because it seems Rigol made an error and it's possible to flash the 1st released version in the older machine, limiting it to 2 channels.
