IQ Histogram Volumetric

UNIQUE: The IQ histogram Volumetric block shows the digital modulation as a 3D vectorscope displaying I and Q as X-Y plot including the time as Z axis plus the sample statistic as a color grade. This gives you a unique 3D view of your digital modulation which only the RTSA-Suite PRO can offer:

The IQ Histogram Volumetric offers a Demodulation (none, ofdm, ofdm_diff), Phase Recovery (none, fixed phase, modulus power, gardner 4, gardner 16, gardner 64), X and Y Source trimming (i, q, r, rq, phi, dphi, phase, band, i4, q4, symbol, symbol4, symbol16, symbol64, symbol256) and adjustable resolution via Value Bins (16 to 256):
