Procedure
1.
Turn DUTs LINE switch ON. Press [INSTR PRESET] [CW] [4] [.] [5] [GHz] [POWER LEVEL] [0]
[dB(m)].
2.
Connect equipment as shown
in
Figure 4-6
(note 1000 pF capacitor shunting DVM
input). Allow
the equipment to warm up for one
hour.
NOTE
In
step
3,
XTAL mode
is
selected.
In this
mode the [dB(m)] terminator
key selects dBV. The dBV value selected corresponds
to
a
voltage
at
which the
DUTs EXT INPUT will
be leveled (see Table
4-14).
The
selected dBV
is displayed in the
ENTRY DISPLAY.
NOTE
If
a
positive polarity crystal detector is being used for this test, the
volt¬
ages given
in Tables 4-12, 4-13, 4-14, and 4-15
will all
be positive.
3.
Press
[XTAL] [6] [dB(m)]. DVM
reading should be within the values shown on the first line in
Table
4-12.
