INTRODUCTION
4-2. This
section
provides instructions for per¬
formance testing the 8414A. If the serial prefix of
your instrument is different from that listed on the
title page of this manual, there are differences be¬
tween your instrument and the instrument de¬
scribed in this manual. See Paragraphs 1-7 and 1-8.
4-3.
Figure 4-1 is the equipment setup for all
performance tests. The procedures in Paragraphs
4-8 through 4-10 check the 8414A performance
for incoming inspection and periodic evaluation.
The tests can be performed without access to the
instrument interior. The specifications in Table 1-1
are the performance standards. Before starting the
performance tests, allow 30 minutes warm-up time
for the 8414A and Network Analyzer.
4-4.
EQUIPMENT REQUIRED.
4-5.
The test instruments and accessories required
to make the performance tests are listed in Table
4-1. Test instruments other than the ones listed can
be used provided their performance equals or ex¬
ceeds the Critical Specifications listed.
4-6. TEST RECORD.
4-7.
Table 4-2 is a performance test record. This
table may be used during the test to record the test
values
obtained,
and
it
provides
a permanent
record of the test values for use at a later time
during calibration or periodic evaluation.
