Logic Analyzer Pro resolution

Hi,

I used the logic analyzer Pro (with the additional board on top of redpitaya1.1/steplab125-14) for the first time today.
It looks like it completely ruins the 10ns resolution advertized: sending a PWM with high level of 3V3 and low of 0, the signal pulse is clipped to 1V8 unless the pulse is veeery large.
Anyone else observed that?
The doc states it won't work without the additional board but I can't believe it. Anyone has insight on why?

Hi,
can you please confirm that your sampling rate is set to 125Msps?
If this is not the case, we will investigate what could be the problem and let you know.
kind regards, Red Pitaya team

Yes resolution is set to 125Msps (in the webapp).

Hi,

For using LA pro application on the STEMlab 125-14 the LA fronted is required.
With the LA fronted maximum sampling rate (125MS/s) is guaranteed.
