Other Parts Discussed in Thread: AWR1443, , DCA1000EVM
Currently I am using AWR1443 BOOST to apply an external trigger from a function generator or pulse generator board in hard trigger mode.
I would like to evaluate it.
For example, when a pulse of 0-3.3V is applied with a pulse generator (TEXIO FGX-22200), the pulse voltage seems to drop to about 0-1.4V. (Pulse generation board etc. will be further lowered.)
By the way, R165 = 0Ω is inserted as shown in the circuit diagram of PROC010B (002) _Sch.PDF.
The 10.0kΩ of R196 has not been changed.
When using an external function generator Are there any precautions to be taken when setting the signal source side, EVM board constants, and AWR1443BOOST?
I will add it because I have found one.
The phenomenon that the voltage drops when SYNC IN is input seems to occur when the DCA1000EVM is connected. (AWR1443BOOST + DCA1000EVM) AWR1443BOOST doesn't seem to happen by itself.
