Test
Procedure
(2 to 10 GHz)
The following procedure lets you measure the 2 to
10 GHz (2.2 to 10 GHz for 68XX5Bs) RF output har-
monic levels to verify that they meet specifications.
1. 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 the frequency indicated on the Test
Record.
2. Set up the Spectrum Analyzer as follows:
a. Span: 5 kHz/div
b. CF: Set to the 682XXB/683XXB frequency
value.
c. RBW: 1 kHz
d. Video Filter Wide: On
3. Adjust the Spectrum Analyzer Peaking control
for maximum signal level, then adjust the Refer-
ence Level Control to place the signal at the top
of the screen graticule.
4. Change the Spectrum Analyzer CF to each of the
harmonic frequencies listed on the Test Record
and record the signal levels. Refer to Table 3-4 for
the specified harmonic signal level limits.
5. Repeat steps 1 through 4 for each of the 682XXB/
683XXB CW carrier and harmonic frequencies
listed on the Test Record. Record the harmonic
signal levels on the Test Record.
