Can anyone with the SDS2kHD and a digital probe set verify what I am seeing? It seems like the digital channel capture rate of the HD is very very slow compared to the SDS2k Plus.
I am only getting 16 wfm/sec on the HD (100ns/div, 2kpts, 8 channel), whereas the Plus is achieving 2.3k wfm/sec with the same settings. I have reset the scope a few times and repeated the tests, and the results are the same.
Also on the HD, fast mode in the acq menu cannot be activated with digital channels on, whereas that's possible on the Plus.
Yes it is DSO like in this. Acquistion, display, next acquistion, display.
If Bus display is off around 16wfm/s max
And with bus decode, it slows bit. here example 8bit bus
With Auto memory (Analog channel length 400pts) around 12wfm/s
With Fixed memory (Analog channel length 20Mpts (400pts displayed and rest outside of screen) around 11wfm/s
Analog channel 40MHz and digital 8 channels all get parallel 20MHz
wfms measured using other scope.
Btw, if wfm/s is lot of faster and signal is changing, how you think what bus decode is displaying.. only way is that it capture just single and display its decoded result and after then next capture... no DPO stacking overlaid (for what).
How it can read if it works like DPO where is severe acquistions overlaid in every display refresh. Think twice.
