Stefan Ritt | Trace Impedance | The DRS4 input is high impedance. So if
you like you can terminate it with 100 Ohm
differentially and route it with 100 Ohm. |

Si Xie | drs_exam is always reading out a sin wave | I see. Where is the code that we can use
to turn off the generator? I thought the
example is taking data with CH1 as the trigger. |

Stefan Ritt | drs_exam is always reading out a sin wave | Sure, that’s correct. The example
program turns on the internal sine wave generator
in case people don’t have a real signal. |
