Introduction
Two types of test
capability are provided in
the
HP 8340A/B and HP 8341A/B Attenuator
Calibration and
Operation
Verification test
software. You may
either
perform
a
calibration of
the internal 90 dB step attenuator or you may perform
an
operation verification of the synthe¬
sizer-
A
listing
of the individual tests provided is
shown by category in Table

Some
of the tests require that the user generated calibration data for the HP 8485A power
sensor and
the
HP 355D
step attenuator (IF Attenuator) be resident on the disc assigned
to
hold this information.
In addition to
this
requirement,,
some
of the
tests must be
run in
sequence to allow the test
result data from
a
previous test to be used for
a
latter test.
Para¬

4.1 provides a
Test Dependency Flow Chart which shows the hierarchy of
the tests
Chapter
3
provides information regarding the software's mass and
data storage addressing
(i.e.,
on which disc the
user generated calibration data and
the test result data will be resident)

Test Dependency
Flow Chart
The flow chart
in
Figure
3
shows the test interdependency
The tests and
utilities included
in
Level
1
of the flow chart
can be run independently and in any order As shown In
Level 2, the
Power Sensor Cal must
be run before performing the Output Power Accuracy test
Finally, as
shown in Level 3, Maximum Leveled Power
is dependent upon Output Power Accuracy
and
the Attenuator Calibration
is
dependent
upon both
Output Power Accuracy
and the
IF
Attenuator Cal The
flow chart
in Figure

applies to both
the
operation
verification and calibra¬
tion portions
of the
software
HP 8340A/B
and
HP 8341A/B
