oscilloscope. There are a number of commands required to set up, trigger, capture, and download the sampled
traces and so the reader is advised to install the application package and study the Python 3 code for the two
channel digital oscilloscope.

Connections
Use Analog Input terminal 1 for Oscilloscope Channel 1 and terminal 5 for Channel 2. Ground both signals
using terminal 9:
Commands
The arguments used in the Oscilloscope commands are:
● addr: the address of the DAQC2plate board being addressed. This can be 0-7 and is set via the
address selection header described above
● C1: input channel 1 enable. This can take on the value of 0 or 1.
● C2: input channel 2 enable. This can take on the value of 0 or 1.
● rate: per channel sample rate of A/D converter. The valid values in samples/second are:
○ 0: 100
○ 1: 200
○ 2: 500
○ 3: 1000
○ 4: 2000
○ 5: 5000
○ 6: 10,000
○ 7: 20,000
○ 8: 50,000
○ 9: 100,000
○ 10: 200,000
○ 11: 500,000
