Initializes spectrum analyzer
.Each
element of trace A is set to 8000 measure-
ment units, which is equal to 0
dBm.
Places trace A in the view mode.
Each element of trace B is set to 7000 measure-
ment units, which is equal to -10
dBm.
Places trace B in the view mode.
Subtracts trace B from trace A.
The result is displayed at 1000 measurement
units which is equal to -70
dBm.
Initializes the spectrum analyzer and sets the
reference level.
Sets trace A to 5000 measurement units, which
is equal to -10
dBm.
Places trace A in the mew mode.
Sets trace B to 4000
measuremtst
units, which
is equal to -20
dBm.
Sets display line to 0
dBm,
which is at 6000
measurement units.
Subtracts trace B minus display line. Result is
4000
-
6000 = -2000 measurements units (ofl
screen).
Subtracts trace A minus modified trace B (5000
-(-2000) = 7000 or 10
dBm.
Notice that this has
resulted in a subtraction of amplitude in
dBm,
-10 dBm -(-20
dBm)
= 10
dBm.
