NI-RFmx 2.1 f4 Critical Update Patch Details

The following fixes were made in RFmx 2.1 f4 (patch) relative to RFmx 2.1

• Crashes when memory usage in a process increases beyond 2 GB.
• Recommended IQ Pre-trigger Time now returns a positive number instead of a negative number. This property is used when using RFmx in Analysis-Only mode.
• For Analysis-Only mode, user needs to adjust t0 of the IQ waveforms according to pre-trigger samples present in the waveform before passing the waveform to Analyze(IQ) function. Refer to the LabVIEW code snippet in Figure 1 for more details. This behavior change affects C/.NET RFmx API as well.
