s = daq.createSession('ni');
ch = s.addCounterOutputChannel('Dev1', 0, 'PulseGeneration');
s.IsContinuous = true;
s.startBackground;
% now try change freq
ch.Frequency = 200;
% produces error:
The property cannot be changed while the Session is running.

Nope, properties for background operations cannot be changed. You have to pause the background operation, and then change the property and start again.
