REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol
Teneyes:
FW 00.01.01.00.02
A small Bug also associated with the Trigger setting of AC Coupling
Note Wim13 has already reported that there is large Trigger Jitter when this mode is selected
I appears that also in this mode of AC coupled Trigger,
the Display of the waveform is NOT in the correct position.
The waveform position is 50nSec to the left (early)
The offset in a fixed amount of time 50nSec
But when the trigger is DC coupling the Position is correct.at the center of the Display
In order to demonstrate,
the animated displays showing a frequency sweeping,
in order to better see where the Trigger point is
Trigger level =0.0
Trigger position should be at the Center
1 DC coupling, NO offset
2. On 100ns/div the offset of 50nsec is 1/2 div
3. On 50ns/div the offset of 50nsec is 1 div
4 On 20ns/div the offset of 50nsec is 2 1/2 div
See next 3 posts
#1 On 100ns/div for DC coupling there is No offset
Teneyes:
#2 On 100ns/div the offset of 50nsec = 1/2 div
Teneyes:
#3 On 50ns/div the offset is 50nsec = 1 div
Teneyes:
#4 On 20ns/div offset 50nsec = 2 1/2 div
Note the 8-12nsec Jitter
Teneyes:
On 50ns/div the offset is 50nsec = 1 div horizontally
And Now with the Trigger level set at 200mV, 1 div Up
