2. Set the AFG to output a 10 dBm, 10 MHz sinewave:
FREQ 1.0E7;
:VOLT 10DBM
INIT:IMM
Perform steps 3 and 4 for each frequency range listed in Table 2-10:
3. Set the spectrum analyzer start frequency and stop frequency to the
values listed in Table 2-6.
4. Measure the amplitude (in dBm) of the highest peak. Subtract the
amplitude of the fundamental (10 dBm) from the reading and record
the result:
result ( dBc) = reading (dBm) − (10 dBm)
