d.
Write down the peak value and note it is = A for later
reference.
6.
Press the
Mod
button on the TSG front panel to turn
modulation on. Notice that
MODON
indicator will appear in
yellow in the top right portion of the screen.
7.
Set the MOD Type to Vector -> QAM and the Source to
External.
8.
Write down the 2000 + 1 MHz amplitude level from the RSA
and note it is = B for later reference.
9.
Calculate the IQ modulation value B–A. Record this value in the
test record.
10.
Continue to test the modulation at each frequency listed in the
test record for the specific instrument model you are testing.
Record the results.
