time difference between 2 channels only ~30-35ps @ 5GSmples/s
Thank you very much! I will check it tomorrow!

Concerning the offset, it looks

transparent-mode voltage
Hello Mr. Stefan Ritt
For DRS4 differential inputs
ranges form 500mV to 1100mV, with ROFS set

The ROFS signal has no effect in the transparent
mode, so you have to adjust O_OFS between
sampling and transparent mode accordingly.

Here's the problem. My external ADC
has 2Vpp differtial input voltage range.
And the common-mode voltage of the inputs

I see your point. Actually I will soon
have the same issue since we design right
now a board with an AD9637 using the transparent

I'm using an AD9252, 0.9V common mode
voltage is suggested and I already use 8
un-switchable level shifters. Just as you

There might be a solution. How do you bias
th input of the
DRS4 chip? If you use a scheme as described

Yes. I use exactly the same scheme as you
mentioned. I'll try your solution.

If using a ROFS of 0.9V, the input would
not between 1.05V~2.05V better non-linearity
area. Is that appropriate?

To get the good linearity, you need indeed
ROFS = 1.05V. With a O-OFS of 0.9V, a zero
input signal would give you DRS_OUT+=1.05V

Martin Petriska
triger for measuring time between pulses in channels
I have two BaF2 detectors with PMT
connected to Ch1 and Ch2. At this time Im
using external triger module to start DRS4.
