Thanks

For the fast ADC/DAC input/outputs on 125-14 (14 bit version) it is DC coupled:

For the fast ADC/DAC input/outputs on 122-16, it is not DC coupled -- and there is an isolation transformer present:

I confirm.

Boards with DC coupling:
STEMlab 125-10
STEMlab 125-14
SIGNALlab 250-12

NO DC coupling :
SDRlab 122-16 (old STEMlab 122.88-16)
