int32 __stdcall niWLANG_SetIdleInterval (niWLANGenerationSession session, char channelString[], float64 idleInterval);

Purpose

Specifies the interframe spacing for signal generation. If you set the NIWLANG_RF_BLANKING_ENABLED attribute to NIWLANA_VAL_FALSE, the toolkit places half of the interframe spacing on either side of the burst in the generated waveform. If you set the NIWLANG_RF_BLANKING_ENABLED attribute to NIWLANA_VAL_TRUE, the toolkit places the interframe spacing at the end of the waveform. The waveform contains zeros for the duration of the interframe spacing.

Note  For higher values of idle interval, LabWindows/CVI may run out of memory. For a large idle interval, you can create a small idle waveform and generate the waveform multiple times using scripting.
