3.2.3 V/R Ratio
Set the ratio of VBW to RBW. This value is different while measuring different kinds of signals:
⚫ Sine/Continuous Wave (CW) signals: Use 1 to 3 (for faster sweeps)
⚫ Pulsed/transient signals: Use 10 (to reduce the influence on the amplitude of transient
signals)
⚫ Noise signals: Generally use 0.1 (to obtain the average of noises)
