Output Power Accuracy Test
12.0 Description
The Output Power Accuracy Test checks the flatness and
accuracy of the synthesizer's RF
output-
The test
is
performed across
the synthesizer's entire frequency range with three
different
power
level settings For this test,
a
power sensor and
power meter are
connected to
the synthesizer's RF output. The data obtained
from
this
test
is
required by the Maximum
Leveled Output Power test and the Attenuator Calibration test.
NOTE
This test will not
run
unless the power sensor has
been characterized
per
the instructions in Chapter
6.
The data
file
generated for the power
sensor must be
on
the data disc currently
in
the disc drive.

12.2 Procedure
1.
The softkeys provided for this test are as follows:
SET
UP
-
Provides
a
graphical display of the Output Power Accuracy test
setup
on the
CRT-
VERIFY
-
Runs
the test which verifies the output power accuracy performance
of the synthesizer This
is the
key you should select to meet
the
requirements for
the
operation verification.
SELECT
-
Allows you to
check the output power accuracy for
a specific fre¬
quency range. Also allows you to select the number of points and
power
level you wish to test. When the
program requests
the
test
parameters,
only enter
the number. For example,
when
the program
requests the start
frequency, enter
4
(not
4 GHz)
No data
is
stored
when this softkey is selected.
JANITOR

Returns
you to the test
menu
Select the desired softkey and respond
to the prompts provided
by
the program-
