Inside the class definition you can add things to locals() [it returns
the actual dictionary being used in class preparation], but I don't know
if this can be relied on or is an implementation detail of CPython.
Anyone know?

But anyway, instead of using a loop, why not just define each one on its
own line:

def mkmeasure(fnname, measparam):
   ...

class Channel:
   frequency = mkmeasure('frequency', 'FREQ')
   falltime = mkmeasure('falltime', 'FTIM')
