Sample tested during initial release and after any redesign or process change that may affect this parameter.
The pulse widths of F1, F2, and CF are not fixed for higher output frequencies. See the Frequency Outputs section.
The CF pulse is always 35 µs in high frequency mode. See the Frequency Outputs section and Table 7.
