Introduction
Introduction
This chapter provides the performance tests outline for Keysight E4981A. The
performance test names are listed in
Table 2-1 . The test descriptions are described
sequentially in the following pages.
NOTE
Allow the analyzer to warm up for at least 30 minutes before you execute any of the
performance tests.
Perform all performance tests in an ambient temperature of 23
±
5
⋅
C
NOTE
The performance tests should be performed periodically. The recommended test interval is
12 months.
The test interval depends on maintenance and the environmental conditions under which
the instrument is used. You may find that the interval could be shortened or lengthened;
however, such a decision should be based on substantial quantitative data.
Test Equipment Required
The required equipment for the performance test is listed in Table 1-1 . Use only calibrated
equipment when doing the performance test.
