As shown in above figures above, a comparator is outputting 16V pulse signal when it is ON.
For some reason I want to lower this voltage around 8V pulse. In Config 1, it is coupled to a voltage divider. In Config 2, it is coupled to a zener clamp. This final 8V pulses will then be coupled to a DAQ which will count the pulses. The reason of stepping down the voltage is that the DAQ has 10V input limit. The DAQ has input impedance 100Gohm.
I can use both Config 1 and 2. But is there an advantage of one configuration to another? Which one would you use and is more convenient?
