Hello,
I cannot use a 1 volt, 20 msec, 50 kHz tone burst to externally trigger the ADC 212/3. What are the minimum requirements for the trigger pulse? |

The external trigger levels are fixed values. You can adjust for delay and slope but not level.
Positive slope external trigger level is about 3 volts.
Negative slope external trigger level is about 1.8 volts.
Your input will have to reach these levels to be compatible with external trigger. Hope this helps. |
