Section IV: Performance Tests
INTRODUCTION
The procedures in this section test the HP 8340B and HP 8341B’s electrical performance using the
specifications given in Section I as the performance standards. These tests are intended for use in
incoming inspection, calibration verification, and post-repair performance verification. All tests can be
performed without access to the interior of the instrument. An HP-lB Operation Verification procedure
is also provided at the end of this section to verify proper HP-lB operation of the instrument.
RECOMMENDED TEST EQUIPMENT
Table 4-2 is a complete list of all required equipment for the tests and adjustments supplied in Section
IV, Performance Tests, and Section V, Adjustments. Test equipment other than that noted in the table
may be substituted if it meets or exceeds the critical specifications indicated in the table.
TEST RECORD
Results of the Performance Test procedures may be tabulated on the test record card located at the
end of this section. Each test lists all of the tested specifications and their acceptable limits. The
results recorded at incoming inspection can be used for comparison in periodic maintenance and
troubleshooting and after repairs or adjustments have been made.
CALIBRATIONCYCLE
This instrument requires periodic verification of performance. The instrument should be checked
using the following performance tests at least once every year.
NOTE
The acronym “DUT” (Device Under Test) is used to describe the HP
8340B or 8341B (HP 8340B/41B) under test. The acronym “LO” S USed to
describe the Local Oscillator.
Options 001, OOS, 006, and 007 apply only to HP 8340B’s.
