a.
Connect
the
equipment
as
shown
in
Figure
4-8A.
Neither
voltmeter
input
can
be
con-
nected to ground.
@ b. Set the 3336 frequency to 10 kHz.
c.
Set
the
3336
amplitude
to
maximum.
The
maximum
output
amplitudes
by
output
are:
124 ohm
135 ohm
150 ohm
600 ohm
+ 1.76 dBm
+1.76 dBm
+1.76 dBm
+ 7.00 dBm
d. Record the voltmeter reading, using the dB scale (Vref).
e. Connect the equipment as shown in Figure 4-8B.
f.
Set
the
3336
frequency
to
each
of
the
test
frequencies
listed
below.
For
each
frequency,
take
a
voltage
measurement,
using
the
dB
scale
(Vpal).
