TEST CAPABILITY
The Attenuator Calibration and Operation Verification Test Software provides the capability to
per¬
form
a
semi-automated operation verification
of
the HP 8340A/B and 8341 A/B synthesized sweepers
in addition to
a
complete calibration (adjust and test) of the
90 dB step attenuator included
with many
of the synthesizers.
The
operation
verification portion of the test
software
is intended to provide
a
90%
confidence level of
the operation of the synthesizer. The operation
verification
is designed for use
as an incoming inspec¬
tion of the synthesizers or as
a
verification of instrument operation after an instrument repair. The
performance tests provided
in
the operation verification are
CW
frequency accuracy, output power
accuracy and flatness, and maximum leveled power. In
addition, a phase
lock loop diagnostic, an
ALC
accuracy verification, and
a
utility for displaying the internal calibration
data are also provided.
The
attenuator calibration portion of the test software provides
the capability to adjust and verify the
performance
of the internal
90 dB step attenuator
included with many of the synthesizers. In addition
to
this, a
semi-automated performance test for
the frequency switching time specification
is
provided.
Both the
90 dB
step attenuator adjustment and
frequency
switching time performance test can only be
performed using
the automated
tests supplied with this
software. These tests should be used to
supplement the manual adjustments and tests provided in the
HP 8340A/B and 8341
A/B operating
and service manuals.
TEST RECORD AND DATA STORAGE
Depending on the test performed, the test
results are presented in
either tabular or graphical form.
The test data includes test limits and the instrument's performance. During testing, you
are
given
a
choice of outputting the test data to
either the system computer CRT or an external
printer, Printed
copies of the test
data
can be used as
a
permanent test
record.
When
a
test
completes,
the measurement data obtained during the test
Is
automatically stored on
a
disc that you have
designated for measurement data storage (described
in
section 3). This allows you
to recover and review the data
at
a
later time. How to implement the
measurement
data review Is
mentioned in section
7
and
described
in section
8
(Test Menu Utility Softkey).
INSTALLATION ON
A
HARD DISC
When copying the software onto
a
fixed disc, (e.g. an
HP 9133H, 9153A, or
any disc with 2:750 Kbytes
of storage),
you must
use the install program, "Install", on disc
1
„
The install program changes the test
software's
labeling to
allow
it
to run on a
Fixed
disc. If
you
do not use the install program, the
software
will
not run on
a
fixed disc. The install
program also
provides a
convenient method to
transfer the software onto
a
floppy
disc.
