2. Select the trace type:
Clear & Write[F2]
Max Hold[F3]
Min Hold[F4]
View[F5]
Blank[F6]
3. If Max Hold[F3] was selected, set the threshold
level.
Note
Traces, 2, 3 and 4 are set to Blank by default.
Trace Math
Description
Performs trace math from two traces (TR1, TR2)
and stores the result in the currently selected
trace. It also performs trace shift.
Math functions
Power Diff
Subtracts the TR1 amplitude
data from the TR2 amplitude
data. The TR1 data TR2 data
are converted to watts. The
result is converted back to
dBm.
Log Diff
Subtracts the TR1 amplitude
data from the TR2 amplitude
data and then adds a
logarithmic reference. Both the
TR1 and TR2 data is in dBm.
The resultant trace of the
subtraction is in dB. When the
result is added to a logarithmic
reference the resulting data is
in dBm.
