Changing the amplitude range, or input Gain
When using the SSA ID, as in this example, the measure-
ment range is 80 dB, unlike the ISM and LOG IDs for which
it is 105 dB. In order to optimize a particular measurement,
provisions have been made to select a value of input gain
directly from the graphic display. The gain can also be
changed from the Setup Menu, as described later in this
manual or it can be changed here.
Step 1
To change the gain, Use the
u
or
d
keys to
highlight the Gain, as shown below.
The gain shifts the dynamic range up
or down. See page 5-3.
Step 2
Use the
r
or
l
arrow keys to change the input
gain.
