(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.

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.
