Currently, when opening an EMI filter (-6 dB bandwidth), the resolution
bandwidth can only be 200 Hz, 9 kHz, 120 kHz, or 1 MHz. At this time,
the detection method can be selected as "quasi-peak".
5.6 【Trace】
As the sweep signal is displayed as a trace on the screen, you
can set parameters about the trace using this key. The analyzer
allows for up to five traces to be displayed at one time, and press
