SRCNORM Source Normalization
Description
The SRCNORM command subtracts trace B from trace A, point by point, adds the display line
value to the difference, and sends the difference to trace A. The SRCNORM function remains in
effect until it is turned off by executing “SRCNORM OFF;
,,.
A common use of trace subtraction is to normalize one trace with respect to another. For
example, traces are frequently subtracted to normalize the spectrum analyzer response when a
tracking generator is used. In such applications, amplitude units in
dBm
should be subtracted.
To accomplish this, the display line should be set to 0
dBm
using DL as shown in the example.
Also see example 2 and 3 in “AMB” for comparison.
