REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol
DEHiCKA:
Salas, I've already got it from another fairy :) That was darn quick, thank you guys for the help.

It is also better to read the first page of this thread if you are going to upgrade the firmware.

This is a re-post from another thread - because I thought the info might be interesting to DS2000 owners.
In regards to how the Rigol decimates a larger number of samples to a smaller number of pixels (e.g. 14k sample length to 700 pixels = 20 samples per pixel when the time base is >= 500ns) - the two common methods being 1/N or Peak-to-Peak:
I did some experimentation using an AWG file of three consecutive short pulses with increasingly higher voltages - with the DSO triggering on the second of the three pulses.
It appears (so far) that the Rigol DS2000 does Peak-to-Peak Decimation from sample to display memory in Normal mode, since if it only displayed every 20th point (using 1/N Decimation), you wouldn't see the amplitude of the third pulse when looking at the display at the 100ms/div setting.
The attached images show 100ms/div and 200us/div displays of Normal mode (@ both 14k and 56Mpts sample lengths) and 100ms/div and 200us/div of Peak Detect mode @ 14kpts.
Peak Detect is a completely different mode of acquisition - I've included it just to show that it can affect the contents of sample memory (as shown at 200us/div) - while Peak-to-Peak Decimation in Normal mode does not.
EvgenyKV:
Hi guys! Soon expires the trial period for options of my DS2102. I heard that there is a method to prolong it. Tell please, whether probably it?

Hi,
i also affilitate to the question from EvgenyKV.
In the 500uV/Div-setting my DS2072 has an offset off about 0,3 Div's. Can a self-cal correct this behavior?
It seems that the bandwidth of the DS2072 is greater than 70MHz.
I look the signal of a 48 MHz crystal oscillator on the DS2072 and a Fluke PM3392A (a nice 200MHz scope). The picture of the two scopes are very alike.
Perhaps the bandwidths graph from Wim13 is typical for all DS2072.
But then, what get a DS2102 buyer more for the money?
I like the hires modus. But the 400 pixels are not enough to display all the 12 bits. Is there a vertical zoom? How can one get full benefit from the hires modus?
Thanks in advance
