Yes, you can have up to 5 measurements at the bottom of the screen at once, optionally with statistics (min, max, avg).
If you enable "Display all" you get all 20 measurements (no statistics) at once in the middle of the screen (20 per channel, so you can display up to 60, if you enable CH1, CH2 and MATH at the same time).

For most of the measurements (at most one at a time of course), you can also enable automatic cursors, that show the relevant points of the measurement on the waveform (e.g. the 10% and 90% mark for the rise time...)

Ok, the very last in my current series of tables  ;D

The waveform update rate of the DS2000 @ 14kPts (single / dual channel - vectors / dots) - tested using a 1MHz sine wave input to channel 1.

What's interesting to note are the following:

1) Rigol has really precisely tuned their design so that the DSO can hit ~50k wfrm/s @ 20ns with a single channel (for the specs and comparisons to DSOX2000 series), but it can't maintain that rate at all with two channels - even though the wfrm/s rates of every other time base setting are fairly similar between single or dual channel.

2) If you are using both channels and want the fastest wfrm/s rate possible, use the 50ns setting instead (using dots, it's the third fastest update rate of the DSO).

3) Dual channel dot mode gives the fastest update rate (faster then single channel vector OR dot mode) at 4 different time base settings.

4) Dual channel dot mode is faster then single channel vector mode at 6 other time base settings.

Hydrawerk:
Thank you. But what's with the 10ns? Anyway, this DS2000 scope is still better than Hameg HMO, LeCroy Wavejet, Tek DPO2000 or even TDS3000.  :-+

marmad:
My last table - really, I promise!  ;D

Rigol DS2000 series acquisition times when using the full 56MPts sample length:

Note: If you do a single-shot with 56MPts @ 1000s time base setting - it will take 7hours, 46 minutes and 40 seconds to complete - grabbing a sample every 0.5ms!

It really annoys me because I use Atmel micros a lot and until recently my company only seemed to be able to order stuff from them and RS (who are possibly even worse, but at least tend to deliver in the morning instead of at 4:30 - "next day" my arse). Their range is pathetic and they used to want £7 for a single part that Mouser were doing for £1.50. Even now Atmel will sell you a debugger for $99 while Farnell want £175 for it.

Have to agree Element14 (FARNELL)  2 years ago wanted $58 plus cents for 1 ATMEGA48V and I found a firm who supplied 100 including freight for less. The other thing that bugs me are SMD resistors 0402 pkg & 603s after searching for half an hour finding prices as low as 2 cents you finally find the higher wattage one and the price is $1 to $2 each min order 10 place it in the cart and there's a minimum of 2000 s__t you say and start the circus again :-- RS is nearly as bad but they put available in 5 to 6 wotking days and after ordering it's on back order 3months, :-- wish they would the length of time before placing the order Who gets their ass kicked for the order spread all over the place yeah! the person ordering not the supplier.

THANKS MY RANT FOR THE WEEK
Rachael :-+
PS Why is RIGOLS 2000 Series model 200MHz Min. Time 2.5ns  and the others 5ns wonder if you can trick the 70MHz to 2.5 HEY MARMAD any ideas.  thats todays as I was trying to find the rise time problem on a job this morning.  GOOD SCOPE THOUGH in thanks to DAVE for the recomendation :-+
