As you turn the knob to the right, the amplitude increases and waveform
shifts to a relatively lower position.
H
As you turn the knob to the left, the amplitude decreases and waveform
shifts to a relatively higher position.
In Figure 2--37, the amplitude is set to 10 dBm. When the amplitude is set to
0 dBm or higher, a blue standard line is displayed indicating 0 dBm.
3.
Set the Ref Level back to 0 dBm after confirming the amplitude operation.
0 dBm reference line
