安诺尼AARONIA实时频谱仪IQ Histogram是德国AARONIA实时频谱分析软件又一个独特的I/Q视图，功能是像"Vector Scope"那样显示数字调制信号，以X-Y轴表示I-Q信号，包含了随时间变化的信号/样本统计。
安诺尼AARONIA实时频谱仪IQ Histogram提供了基本的参数设置:

• Sample Delta(bypass, sub, add, mul, rotate and adjustable emphasize)；
• 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)；
• adjustable resolution via Value Bins (16 to 1024)；

更新：目前安诺尼AARONIA实时频谱仪IQ Histogram增加了Grid Overlays参数设置（UPDATE: We have just added a fully scalable Modulation Grid Overlay for QAM (BPSK, qpsk, 16qam, 64qam, 256qam, 1024qam, 4096qam) and Radial to the IQ Histogram block which you can select from Main -> Grid Overlays:）：

• QAM (BPSK, qpsk, 16qam, 64qam, 256qam, 1024qam, 4096qam)；
• Radial；
