Introduction
For your convenience, this supplement provides information to assist you in
using the
HP
8340A/B
and 8341 A/B Attenuator Calibration and Operation Verification
Test Software,
HP
part number 08340-10009, provided
with this document- The information begins with
a gen¬
eral overview of the
software,
continues with the
equipment
required and modifications which
can be
made
by the operator, and finally ends with how to run the tests.
1.1
Format
of the Disc Containing the Software
The test software included with this documentation is
being supplied on
a
double sided 3-5"
microfloppy. Any
access
to or copying of the programs on the software disc requires the use
of
a
double sided
3 5" microfloppy disc
drive.
Two examples of this type of disc drive are the
3
5" floppy
drive in
the HP 9133H and the
3.5" floppy drives
In
the HP
9122D-
1.2
Test Capability
The Attenuator Calibration and Operation Verification Test Software provides the
capability to
perform a
semi-automated
operation verification of the HP
8340A, 8341A, 8340B,
and 8341
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°o confidence
level of the
operation
of the synthesizer The operation verification
is designed for use as an
incoming Inspection of the synthesizers or as
a
verification of instrument operation after
an
instrument repair- The performance
tests provided
in the
operation verification are
CW
fre¬
quency accuracy, output power accuracy and flatness, and maximum leveled power.
In
addi¬
tion, 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 synthe¬
sizers.
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 test supplied
with this software. These tests should be used to supplement the manual adjustments and
tests provided in
the HP 8340A, 8341A, 8340B and 8341
B
operating and service manuals
1.3
Test Record
Depending
on the test which
is performed, the test results will be presented
in
either tabular or
graphical form.
The
test
data
Includes test limits and the instrument's performance During
the testing, the operator
is
given a
choice of either outputting the test data to the
CRT
of the
system computer or to
an
external
printer.
Printed copies of the test data may be used as
a
permanent test
record
