I made some more measurements with the ADS1013D today. This time with a 3.3V TLL square wave signal. The generator I used is a SignalForge SF1000 that is a combined digital and RF generator that can output:
- AC Coupled Output 100 KHz to 1 GHz
- Differential Output 50 MHz to 1 GHz
- TTL Output 1 Hz - 110 MHz
It has fairly good performance and I would assume that the result is limited by the oscilloscope.
1 Hz input with single trigger mode
Rise time is ~14 ms.
Square wave 10 MHz
Looks fairly good.
Square wave 20 MHz
No so nice...
