4.15. Max Mix Level
Set max input level of mixer according to the manaitude of signal.
Key points:
 For bigger input signal, select small max mixing level in order to increase input attenuation and
reduce distortion. For smaller input signal, select big max mixing level in order to reduce input
attenuation and distortion.
 Paramter in formula 2-3, are always changing on the basis of max mixing level.
 You can modify this parameter by numeric keys, knob and arrow keys. For more details, please
refer to “Parameter Input”.
Table 2-11 Max mix level
5. Sweep and Function Settings
Set the parameters of RBW (Resolution Bandwidth), VBW (Video Bandwidth) and Dectector.
5.1. RBW
Set the RBW (Resolution Bandwidth) in order to distinguish two close signals.
Key points:
 Reducing the RBW to get higher frequency resolution, but will cause the longer sweep (In Auto
Sweep mode, sweep time will be affected both by RBW and VBW).
 In Auto RBW mode, RBW decreases with the span (non-zero span).
 You can modify this parameter by numeric keys, knob and arrow keys. For more details, please
refer to “Parameter Input”.
