3) Press key to pop up the function menu, and select [Peak] to activate the frequency cursor and
make it jump to the peak position of the signal on the display screen. The frequency and magnitude
values can be read out by the cursor and displayed in the active functional area. At this time, the
cursor reading frequency is 1GHz and the magnitude is about -29.96dBm, as shown in Fig. 3.17.

For the 9 kHz~30 MHz, 20 MHz~3.6GHz and 3.6GHz~8 GHz frequency bands, the maximum input level
is respectively -13dBm, +3dBm (attenuator is on) and -24dBm. If the signal level is higher than this limit,
a power attenuator must be installed at the RF input end of the monitoring receiver, otherwise the
