e.
Set the Distortion Analyzer
to measure
distortion
at 10 kHz.
f. Verify that the
Modulation
Analyzer
reading
is between
93
kHz
to 107 kHz,
(9.99
kHz if
the
Generator has
Option
-651
installed)
and the THD is less
than 1
%
as the UUT
frequency
is stepped
up to 1045 MHz in 50-MHz
steps.
(Tip: use the
instrument
FREQ
STEP feature.)
g.
Set the
LFSSG to
0.4 kHz and
adjust its
level so the DVM
reads
707. 1 mV
rms.
h. Program the
Modulation Analyzer
to measure FM in a
0.05-kHz to 3-kHz
bandwidth.
i. Set the
Distortion Analyzer
to
measure distortion
at 0.4 kHz.
j.
Verify
that the Modulation
Analyzer
reading
is between 93 kHz to
107
kHz
(9.99
kHz if the
Generator
has
Option
-651
installed), and
the
THD is less
than
1% as the UUT frequency
is stepped down to
245 MHz in 50-MHz
steps.
