What's the Red Block mean just after data?
[It is just a question mark, such as can be seen in the enlarged image (200us). At the same place is a red block in the original picture 500us.
if it is the same block, why is the yellow trace not the same and the Block data show what looks the is a "BIT" different ?
Reading the Userguide . page 7-8 , End of Frame error , changes from block to ? when you zoom in

Nice!
With RUU , after recording frames, then playing them back in Repeat Mode, the repeat mode check box is allowed to be unchecked but the DS2072 will not allow it to be changed, So the RUU shows no "Repeat" mode but the DSO is running in 'Repeat mode'.
If the RUU play is "Paused" then the check box is updated to show still in Repeat Mode,
I'll make sure to disable the check box when the DSO is playing in the next version.
Keep in mind though, the software buttons and check boxes in RUU can't normally control the DSO in any way that you can't do from the front panel of the Rigol (unfortunately).
But I do like using RUU for jumping the DS2072 play 'Interval' from 200ns to 2 seconds without having to turn the selection knob many turns
So I loaded wfm file , then saved it again
changed offset then saved again
19 bytes changed. in 5 groups
the Data did not change, kind implies there is and Offset parm in the 5 groups
back to testing
Exploring Trace files and patching with blanks to see locations first , with NO file read errors
see 2 breaks in trace below
looking like trc files are bit maps coordinates
BTW I looked at CSV files and most are 1400 values if saving displayed
but if DSO is set to Maximum then only to pts are save to the CSV .
for Max. Saving:
at 5ns -> 140 values
at 10ns -> 280 values
at 20ns-> 560 values
.....
these values are extrapolated into the displayed CSV file of 1400 line.rows
.
.
Exploring Trace files
Size of file? Number of bytes per channel?
