2. Set up the 682XXB/683XXB as follows:
a. Reset the instrument by pressing
SYSTEM
,
then
Reset
. Upon reset the CW Menu is dis-
played.
b. Press
Edit L1
to open the current power level
parameter for editing.
c. Set L1 to the lesser of +10 dBm or the maxi-
mum leveled power level for the instrument
being tested (refer to Table 3-2, page 3-6).
d. Press
Edit F1
to open the current frequency
parameter for editing.
e. Set F1 to 10 MHz.
3. On the Spectrum Analyzer, measure the worst
case harmonic and non-harmonic signals for the
10 MHz carrier. Record their presence by enter-
ing the levels on the Test Record. Refer to Table
3-3 for the specified level limits.
NOTE
Harmonics appear at multiples of the CW
frequency and diminish quickly as the CW
frequency gets greater than 1 GHz.
4. Repeat step 3 with F1 set first to 20 MHz, then
set to 30 MHz. Measure the worst case harmonics
and non-harmonics for each carrier frequency
and record their presence by entering their levels
on the Test Record.
5. Change the Spectrum Analyzer setup as follows:
a. Span: 100 MHz/div
b. CF: 500 MHz
6. Repeat step 3 with F1 set to 40 MHz. Measure
the worst case harmonic and non-harmonic sig-
nals for the 40 MHz carrier and record their pres-
ence by entering their levels on the Test Record.
7. Change the Spectrum Analyzer setup as follows:
a. Span: 200 MHz/div (or maximum span width)
b. CF: 1 GHz (N/A if at maximum span width)
8. Repeat step 3 with F1 set to 350 MHz. Measure
the worst case harmonic and non-harmonic sig-
nals for the 350 MHz carrier and record their
