1 Calibrating

This chapter identiﬁes the performance test procedures which test the electrical performance of the analyzer. Allow the analyzer to warm up in accordance with the temperature stability speciﬁcations before performing the tests in this chapter.

None of the test procedures involve removing the cover of the analyzer.

Calibration

Calibration veriﬁes that the analyzer performance is within all speciﬁcations. 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 veriﬁcation tests table for your speciﬁc analyzer.

Operation Veriﬁcation

Operation veriﬁcation only tests the most critical speciﬁcations. These tests are recommended for incoming inspection, troubleshooting, or after repair. Operation veriﬁcation requires less time and equipment than the calibration. See the performance veriﬁcation tests table for your analyzer.

Calibration Cycle

The performance tests in Chapter 2 , "Performance Veriﬁcation

Tests"should be used to check the analyzer against its speciﬁcations

once every year. Speciﬁcations 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.

When A 3335A Source Is Not Available

The 3335A Synthesizer Level Generator signal source has become obsolete because parts used in the manufacture of this instrument are no longer available from suppliers. To meet the need of our customers, this calibration guide has been revised to add new performance veriﬁcation tests that do not use the 3335A Synthesizer Level Generator. This revision includes the addition of signal sources required to replace the 3335A, changes to the test equipment setup illustrations, and changes in the steps required to execute the procedures.

Since all of our customers will not need to replace their 3335A Synthesizer Level Generators immediately, the original performance tests which use the 3335A signal generator have been retained. The revisions have been incorporated in this calibration guide as Chapter

2a, "PerformanceVeriﬁcationTests:If 3335A Source Not Available" and Chapter 3a, “Performance Test Records: If 3335A Source Not Available.”

Performance Veriﬁcation Test Tables

The tables on the following pages list the performance tests in Chapter 2 and Chapter 2a. 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. A diamond indicates that the test is required for operation veriﬁcation. Note that some of the tests are used for both calibration and operation veriﬁcation.

Safety

Familiarize yourself with the safety symbols marked on the analyzer, and read the general safety instructions and the symbol deﬁnitions given in Chapter 12 , “Safety and Regulatory Information,” before you begin verifying performance of the spectrum analyzer.

Before You Start

There are four things you should do before starting a performance veriﬁcation test:

• Switch the analyzer on and let it warm up in accordance with the temperature stability speciﬁcation.

• Read “Making a Measurement” in your analyzer user's guide.

• After the analyzer has warmed up as speciﬁed, perform the self-calibration procedure documented in “Improving Accuracy With Self-Calibration Routines” in the 8590 E-Series and L-Series

Spectrum Analyzer User's Guide, 8591C Cable TV Analyzer, Spectrum Analyzer Reference User's Guide,or8594Q QAM Analyzer Spectrum Analyzer Reference User's Guide. The performance of the

analyzer is only speciﬁed 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 Veriﬁcation Test Record described below in “Recording the test results.”

Test Equipment You Will Need

Table 1-8 through Table 1-11 list the recommended test equipment for

the performance tests. The tables also list recommended equipment for the analyzer adjustment procedures which are located in the 8590 Series Analyzers Assembly-Level Repair Service Guide. Any equipment that meets the critical speciﬁcations given in the table can be substituted for the recommended model.

If a 3335A Synthesizer/Level Generator is not available, see Table 1-8 through Table 1-10 for alternative recommended test equipment, accessories, and adapters.

26 Chapter1

Page 27

Calibrating

Recording the Test Results

Performance veriﬁcation test records, for each spectrum analyzer, are provided in Chapter 3 , "Performance Test Records" and Chapter 3a,

"Performance Test Records: If 3335A Source Not Available" following

the tests. Each test result is identiﬁed as a TR Entry in the performance test and

on the performance veriﬁcation test record. We recommend that you make a copy of the performance veriﬁcation test record, record the test results on the copy, and 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 veriﬁcation test. To perform self-calibration, press must be up to operating temperature in order for this test to be valid. Press continuously fails one or more speciﬁcations, complete any remaining tests and record all test results on a copy of the test record. Then refer to Chapter 1 for instructions on how to solve the problem.

CAL STORE when the test is complete. If the analyzer

CAL then CAL FREQ & AMPTD. The instrument

Periodically Verifying Operation

The analyzer requires periodic veriﬁcation of operation. Under most conditions of use, you should test the analyzer at least once a year with either operation veriﬁcation or the complete set of performance veriﬁcation tests.

If the spectrum analyzer is not equipped with a Precision Frequency Reference, perform “10 MHz Reference Output Accuracy,” instead.

This test measures the warmup characteristics of the 10 MHz reference oscillator. The ability of the 10 MHz oscillator to meet its warmup characteristics gives a high level of conﬁdence that it will also meet its yearly aging speciﬁcation.

A frequency counter is connected to the 10 MHz REF OUTPUT. After the spectrum analyzer has been allowed to cool for at least 60 minutes, the spectrum analyzer is powered on. A frequency measurement is made ﬁve minutes after power is applied and the frequency is recorded. Another frequency measurement is made 25 minutes later (30 minutes after power is applied) and the frequency is recorded. A ﬁnal frequency measurement is made 60 minutes after power is applied. The difference between each of the ﬁrst two frequency measurements and the last frequency measurement is calculated and recorded.

The related adjustment for this procedure is “10 MHz Precision Frequency Reference Accuracy Adjustment.”

Equipment Required

Frequency counter Frequency standard Cable, BNC, 122 cm (48 in) (2 required)

Procedure

The spectrum analyzer must have been allowed to sit with the power for at least 60 minutes before performing this procedure. This adequately simulates a cold start. A cold start is deﬁned as the spectrum analyzer being powered on after being for at least 60 minutes.

1. Allow the spectrum analyzer to sit with the power off for at least 60

minutes before proceeding. Connect the equipment as shown in

Figure 2-2.

2. Set the spectrum analyzer LINE switch on. Record the Power On

10. Residual FM, 8591E and 8591C

This test measures the inherent short-term instability of the spectrum analyzer LO system. With the analyzer in zero span, a stable signal is applied to the input and slope-detected on the linear portion of the IF bandwidth ﬁlter skirt. Any instability in the LO transfers to the IF signal in the mixing process. The test determines the slope of the IF ﬁlter in Hz/dB and then measures the signal amplitude variation caused by the residual FM. Multiplying these two values yields the residual FM in Hz. The narrow bandwidth options use a 300 Hz span. This span is not speciﬁed, however, it is tested in “Frequency Span Accuracy.”

There are no related adjustment procedures for this performance test.
