Setting amplitude
1.
The reference level will be shown at
the top of the display grid. To get a
better dynamic range, the real signal
peak point should be located at or
near the top of display grid
(reference level). The reference level
is also the maximum value on Y axis.
Here we reduce to 20dB reference
level to increase the dynamic range.
2.
Press the
AMPTD
button. The
amplitude setting menu will pop up
and the
reference level
soft key will
be activated. The reference level can
be input at the top left of the display
grid. Input
-20
using the numeric
keypad and set the unit to
dBm
. You
can also use the ↓ key or the knob for
adjustment.
The reference level is set at -20dBM,
which is the signal peak value near
the top of the grid. The balance
between the signal peak value and
noise is dynamic range.
