6.2.5.3.1 Activating the Trace Difference Function
Use
You can use the R&S FS300’s MATH function to directly determine differ-
ences between signals by forming the difference of two traces. The new ref-
erence for the difference trace is in the center of the measurement diagram
(50 %). The difference trace can be moved within the measurement diagram
by changing the reference.
Turning on the
difference
function
1.
Press the
function key
in the
submenu.
The new trace, Trace 1, is the difference of the old traces, e. g. T1 = T1 -
T2. Each measured value represented by Trace 2 is subtracted from the
corresponding measured value represented by Trace 1.
