Rigol HDO1000 and HDO4000 12bit oscilloscopes launched in China

The rest of the FFT test...
Playing from 500ms timebase till 5ms, watch the info on the window (RBW, samplerate), I´ve changed nothing else except the timebase.
I can not guarantee the correct order of the pics as the forum software somehow shuffled them since a couple of months. ::)
More FFT test I don´t make, imho it´s too buggy.
Next play is connecting the bodnar pulser. ;)

Last for today, the bodnar pulser.
I´ve been looking for switching the display mode (dot/vectors), to my surprise you can´t change the mode, it´s always vector.
(BTW, to the owners: I haven´t found the possibility to save all the screen content to the stick, when doing a screenshot, all open menus won´t be captured, so I must use a camera)
Then connecting the pulser, measure the rise time: 1.6ns sounds plausible to me, while the signal looks a little bit "filtered".
Following an idea, I´ve activated the second channel and to my surprise, the pulse on ch1 is getting "faster" and overshoots came up.
(1.2ns when 2 channels are active).
When all channels are active, the overshoot of the pulse gets "blurried" while the risetimes decreases to 1.5ns .
Hm...

Purposely done to foil rf-loop's investigations of false dots. ;)

Inspect the Save/Recall menu for the switch to show or hide menus in screenshots.
Do you forget your Siglent has that ?

Indeed.

No, why should I...This was the first section I´ve looked for. ;)
Edit:
BTW, the \$\Omega\$ symbol in the channelbox stands for 50 Ohm input... :P

Snip of the manual:
--- Quote ---19.1 Display Type
This series oscilloscope provides the "Vector" display mode in which the sample
points are connected by lines and displayed. In most cases, this mode can provide the
most vivid waveform for you to view the steep edge of the waveform (such as square
waveform).

LOL....
And the manual telling me another thing, about the screenshot...
There is no possibility to save the whole screen content.... :palm:
