Continous Sweep THD VI takes too long to execute when max harmonic is high

Continous Sweep THD VI takes too long to execute when max harmonic is high


1. Sample faster

2. Break the sweep into two segments (high and low frequency) and decrease the maximum harmonic for the high frequency sweep

3. Parse the acquired waveform and perform explicit resampling to angular domain (see Continuous Sweep* (Advanced) example VI). Explicitly maintain multiple resampled signals (each with appropriate sampling for the frequency resolution)
