General Safety Considerations
WARNING No operator serviceable parts inside. Refer servicing to
quali ed personnel. To prevent electrical shock, do not
remove covers.
If this instrument is not used as speci ed, the protection
provided by the equipment may be impaired. This
instrument must be used in a normal condition (in which
all means for protection are intact) only.
For continued protection against re hazard, replace line
fuse only with same type and rating ([F 5A/250V]). The
use of other fuses or material is prohibited.
CAUTION Before switching on this instrument, make sure that the line
voltage selector switch is set to the voltage of the power
supply and the correct fuse is installed.
Always use the three-prong ac power cord supplied with this
instrument. Failure to ensure adequate earth grounding by
not using this cord may cause instrument damage.
Only clean the instrument cabinet using a damp cloth.

Calibrating
This chapter identi es the performance test procedures which test the electrical
performance of the analyzer.
Allow the analyzer to warm up in accordance with the temperature stability
speci cations before performing the tests called out in this chapter.
None of the test procedures involve removing the cover of the analyzer.
Calibration
Calibration veri es that the analyzer performance is within all speci cations. It
is time consuming and requires extensive test equipment. Calibration consists of
all the performance tests. For a complete listing of the performance tests, see
the performance veri cation tests table for your speci c analyzer.
Operation Veri cation
Operation veri cation only tests the most critical speci cations. These tests
are recommended for incoming inspection, troubleshooting, or after repair.
Operation veri cation requires less time and equipment than the calibration.
See the performance veri cation tests table for your analyzer.
Calibrating 1-1
Calibration Cycle
The performance tests in Chapter 2 should be used to check the analyzer against
its speci cations once every year. Speci cations are listed in this calibration
guide.
The 300 MHz frequency of the CAL OUT signal must be checked at the same
time and adjusted if necessary. Refer to the \10 MHz Frequency Reference
Adjustment" procedure in the assembly-level repair service guide.

Performance Veri cation Test Tables
The tables on the following pages list the performance tests in chapter 2. Select
the analyzer option being calibrated and perform the tests marked in the option
column.
A dot indicates that the test is required for calibration. Note that some of the
tests are used for both calibration and operation veri cation (marked with 45).

Safety
Familiarize yourself with the safety symbols marked on the analyzer, and read
the general safety instructions and the symbol de nitions given in the front of
this guide before you begin verifying performance of the EMC analyzer.
Before You Start
There are four things you should do before starting a performance veri cation
test:
Switch the analyzer on and let it warm up in accordance with the
temperature stability speci cation.
Read \Making a Measurement" in your analyzer user's guide.
After the analyzer has warmed up as speci ed, perform the self-calibration
procedure documented in \Improving Accuracy With Self-Calibration
Routines" in the HP 8590 EM-Series EMC Analyzer User's Guide. The
performance of the analyzer is only speci ed after the analyzer calibration
routines have been run and if the analyzer is autocoupled.
Read the rest of this section before you start any of the tests, and make
a copy of the Performance Veri cation Test Record described below in
\Recording the test results."
Test equipment you will need
Tables 1-6 through 1-9 list the recommended test equipment for the performance
tests. Any equipment that meets the critical speci cations given in the table can
be substituted for the recommended model.
Recording the test results
Performance veri cation test records, for each EMC analyzer, are provided in
the chapter following the tests.
Each test result is identi ed as a TR Entry in the performance tests and on the
performance veri cation test record. We recommend that you make a copy of
the performance veri cation test record, record the test results on the copy, and
Calibrating 1-9
keep the copy for your calibration test record. This record could prove valuable
in tracking gradual changes in test results over long periods of time.
Frequency and amplitude self-calibration
Perform the frequency and amplitude self-calibration routines at least once
per day, or if the analyzer fails a veri cation test. To perform self-calibration,
press 4CAL5 then CAL FREQ & AMPTD . The instrument must be up to operating
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
temperature in order for this test to be valid. Press CAL STORE when the test is
NNNNNNNNNNNNNNNNNNNNNNNNNNNNN
complete. If the analyzer continuously fails one or more speci cations, complete
any remaining tests and record all test results on a copy of the test record.
Then refer to the \Customer Support" chapter for instructions on how to solve
the problem.
Periodically verifying operation
The analyzer requires periodic veri cation of operation. Under most conditions
of use, you should test the analyzer at least once a year with either operation
veri cation or the complete set of performance veri cation tests.
