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?
Is using the window trigger the only way to get get a waveform across all the sample points? For some reason, I cannot move the trigger position to the left in Edge trigger mode.
Perhaps there was an update which allows the trigger position to be moved to the far left while in edge trigger mode? Weird.
Indeed. That is my biggest expectation for the MSO5000 is something proportionately for nothing
I wish they’d hurry up and fix the bugsThe MSO5000 is frustrating. It's so close to absolutely crushing anything out there yet the slow UI and unsophisticated case design are letting it down. I have the feeling that the difference isn't even very significant in terms of NRE and manufacturing.
I have a MSO5000.
I absolutely do not understand how it's UI is could be considered slow.
The Tektronix MSO4034B I have at work running the latest firmware, is far slower and crashes often when I do simple scope usage tasks like just changing the channel voltage scaling.
Moving signals across the screen is very sluggish. That's not really acceptable in a device in this bracket.
Feel free not to buy one.
You'll miss out on getting a four channel, 350MHz, 8GSamp/sec., 400Mb memory, 'scope for under $1000 though.
Your choice.

Hmm -- I may be misunderstanding the question? When you say "move the trigger to the left", you mean the left edge of the screen?
To my knowledge, this has always been possible with the DS1054Z, in any trigger mode, and it certainly is possible now. In fact, you can move the trigger point well beyond the left edge of the screen. The "delay" display in the upper right of the screen will then tell you the time difference between the trigger point and the time window visible on the screen.
For you, what happens when you rotate the "horizontal position" knob to the left?
If I turn the knob counterclockwise, the trigger position appear to move left (shown in attached picture), however the trigger position is still at time 0 seconds. So if I save and plot the data, the signal will begin around halfway into the signal array.
However if I use a window trigger (shown in attached picture) and move the time to to (Samples)/(Samplerate)/2,
or as shown in the picture (1200[points]/5e8[points/sec])/2 = 1.2e-6 seconds.
then when I save and plot the data, the sinewave starts at the beginning of the array.
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.
On age degradation the only thing that worries me is the crappy feet. They feel like they’re going to die first.

There's often mentions around here that the rigol's displayed 'dots' are interpolated, I dunno meself.
