NOTE
If two or more spectrum components are involved at a similar level, it is necessary to use a
filter in order to prevent unnecessary spectrum components from entering the receiver port;
in this way, you can prevent the total magnitude from reaching a damage level of 6.3 Vp-p.
Procedure for setting measurement parameters
Follow the steps below to set the measurement parameters. In this case, we measure each
parameter of magnitude, phase, and group delay in conversion loss (S12).
Step 1. Press (or ) to activate the channel you want to measure.
Step 2. Press to set
Num of Traces
to
3
.
Step 3. Press
Allocate Traces
to select the Graph Layout ( ).
Step 4. Press to set the measurement parameter to
S12
.
Step 5. Press to set
LogMag
(magnitude) to Trace 1.
Step 6. Press to select Trace 2.
Step 7. Press to set the measurement parameter to
S12
.
Step 8. Press to set
Phase
(phase) to Trace 2.
Step 9. Press to select Trace 3.
Step 10. Press to set the measurement parameter to
S12
