I am duplicating a test station from another location. They had a T7 Pro, but did not need 802.11, so it is unused in the application. Assuming that their code makes no use of the WiFi, do I need to buy a T7 Pro? Is the T7 code-compatible except for WiFi?

Thanks

T7-Pro vs. T7

T7-Pro vs. T7
The T7-Pro has the following additional features:

802.11b/g WiFi connectivity.
Low-Speed and High-Resolution (24-bit) sigma-delta ADC.
Battery Backed RTC for stand-alone data logging.
Factory Installed microSD card for stand-alone data logging.

Assuming you are not using any of those, the same code should run on a T7 or T7-Pro.

One slight difference is that the default ResolutionIndex of 0 equates to a 8 on a T7 and 9 on a T7-Pro. So if you are using ResolutionIndex=0 you could see slightly different time/sample and noise. See Table A.1.4:
