Is it possible to change frequency of hardware generated PWM on the fly?

 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.
