minimum T clock period specifies the minimum TClk period, in seconds. The minimum period for a single chassis/PC is 200 ns. If the specified value is less than 200 ns, NI-TClk automatically coerces the minimum TClk period to 200 ns. For multichassis synchronization, adjust this value to account for the propagation delays through the various devices and cables. Valid values are 0.0 s to 0.050 s (50 ms), inclusive.
