Calibrating

This chapter contains performance test procedures which test the electrical performance of the spectrum analyzer.

Allow the spectrum analyzer to warm up in accordance with the Temperature Stability specification in Chapter 2 before performing the tests in this chapter.

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

1

Calibration

Calibration verifies that the spectrum analyzer performance is within all specifications listed in

Chapter 2. It is time consuming and requires extensive test equipment. Calibration consists of all the performance tests. See ‘Ihble l-l for a complete listing of the performance tests.

Operation Verification

Operation verification consists of a subset of the performance tests. See Table l-l. Operation verification tests only the most critical specifications of the spectrum analyzer. These tests are recommended for incoming inspection, troubleshooting, or after repair. Operation verification requires less time and equipment than the calibration.

HP 859013 Spectrum Analyzer Calibrating l-l

The following table lists the performance tests included in this chapter. Select the spectrum analyzer option being calibrated and perform the tests marked in the option column. Note that some of the tests are used for both calibration and operation verification (marked with 0).

Safety

Familiarize yourself with the safety symbols marked on the pulse generator, and read the general safety instructions and the symbol definitions given in the front of this manual before you begin verifying performance of the pulse generator.

Before You Start

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

Switch the spectrum analyzer on and let it warm up in accordance with the Temperature

Stability specification in Chapter 2.

n

Read “Making a Measurement” in Chapter

2

of the

HP 8590 Series Spectrum Analyzer User’s

Guide.

n

After the spectrum analyzer has warmed up as specified, perform the Self-Calibration

Procedure documented in “Improving Accuracy With Self-Calibration Routines” in

Chapter

2

of the

HP 8590 Series Spectrum Anulyzer

User’s Guide. The performance of the spectrum analyzer is only specified after the spectrum analyzer calibration routines have been run and if the spectrum analyzer is autocoupled.

n

Read the rest of this section before you start any of the tests, and make a copy of the

Performance Test Record described in “Recording the Test Results.”

Test equipment you will need

Tables l-2 through l-4 lists the recommended test equipment for the performance tests. The tables also lists recommended equipment for the spectrum analyzer adjustment procedures which are located in the

HP 85900 Spectrum Anulyzer Service

Guide. Any equipment that meets the critical specifications given in the table can be substituted for the recommended model.

Recording the test results

A performance test record is provided at the end of this chapter.

Each test result is identified as a

TR Entry

in the performance tests and on the performance test record. We recommend that you make a copy of the performance 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.

If the spectrum analyzer doesn’t meet specifications

If the spectrum analyzer fails a test, rerun the frequency calibration and amplitude calibration routines by pressing CAL FREQ B AMPTD . Press CAL STORE , then repeat the verification test.

If the spectrum analyzer still 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 3, “If You Have a

Problem,” for instructions on how to solve the problem.

HP 8590D Spectrum Analyzer Calibrating 1-3

Periodically verifying operation

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

6. Sweep Time Accuracy

This test uses a synthesizer function generator to amplitude modulate a 500 MHz CW signal from another signal generator. The spectrum analyzer demodulates this signal in zero span to display the response in the time domain. The marker delta frequency function on the spectrum analyzer is used to read out the sweep time accuracy.

There are no related adjustment procedures for this performance test.

7. Scale Fidelity

A 50 MHz CW signal is applied to the INPUT 50 61 of the analyzer through two step attenuators.

The attenuators increase the effective amplitude range of the source. The amplitude of the source is decreased in 10 dB steps and the analyzer marker functions are used to measure the amplitude difference between steps. The source’s internal attenuator is used as the reference standard. The test is performed in both log and linear amplitude scales.

The related adjustment for this performance test is “Log and Linear Amplitude Adjustment.”

8. Reference Level Accuracy

A 50 MHz CW signal is applied to the INPUT 50 62 of the spectrum analyzer through two step attenuators. The attenuators increase the effective amplitude range of the source.

The amplitude of the source is decreased in 10 dB steps and the spectrum analyzer marker functions are used to measure the amplitude difference between steps. The source’s internal attenuator is used as the reference standard. The test is performed in both log and linear amplitude scales.

It is only necessary to test reference levels as low as -90 dBm (with 10 dB attenuation) since lower reference levels are a function of the spectrum analyzer microprocessor manipulating the trace data. There is no error associated with the trace data manipulation.

The related adjustment for this procedure is “A12 Cal Attenuator Error Correction.”

Switching Uncertainties

To measure the absolute amplitude calibration uncertainty the input signal is measured after the self-Cal routine is finished.

To measure the resolution bandwidth switching uncertainty an amplitude reference is taken with the resolution bandwidth set to 3 kHz using the marker-delta function. The resolution bandwidth is changed to settings between 3 MHz and 1 kHz and the amplitude variation is measured at each setting and compared to the specification. The span is changed as necessary to maintain approximately the same aspect ratio.

The related adjustment procedure for this performance test is “Crystal and LC Bandwidth

10. Calibrator Amplitude and Frequency Accuracy

This test measures the accuracy of the spectrum analyzer CAL OUT signal. The first part of the test characterizes the insertion loss of a Low Pass Filter (LPF) and 10 dB attenuator. The harmonics of the CAL OUT signal are suppressed with the LPF before the amplitude accuracy is measured using a power meter. A frequency counter is used to measure the frequency accuracy of the CAL OUT signal and the measured frequency is compared to the specification.

Procedure

Part 1: LPF, Attenuator, and Adapter Insertion Loss Characterization

1. Zero and calibrate the measuring receiver and power sensor in LOG mode as described in the measuring receiver operation manual.

Caution

Do not attempt to calibrate the low power sensor without the reference attenuator or damage to the low power sensor will occur.

2. Zero and calibrate the power meter and the low power sensor, as described in the power meter operation manual.

3. Press INSTRUMENT PRESET on the synthesized sweeper. Set the controls as follows:

CW . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ..300MHz

4. Connect the equipment as shown in Figure l-10. Connect the low power sensor directly to the power splitter (bypass the LPF, attenuator, and adapters). Allow the power sensors to settle before proceeding.

5. On the measuring receiver, press RATIO mode. Power indication should be 0 dB.

6. On the power meter, press the dB REF mode key. Power indication should be 0 dB.

7. Connect the LPF, attenuator and adapters as shown in Figure l-10.

8. Record the measuring receiver reading in dB. This is the relative error due to mismatch.

Mismatch Error dB

9. Record the power meter reading in dB. This is the relative uncorrected insertion loss of the

LPF, attenuator, and adapters.

Uncorrected Insertion Loss dB

10. Subtract the Mismatch Error (step 8) from the Uncorrected Insertion Loss (step 9). This is the Corrected Insertion Loss.

Corrected Insertion Loss dB

Example: If the Mismatch Error is +0.3 dB and the Uncorrected Insertion Loss is -10.2 dB, subtract the mismatch error from the insertion loss to yield a corrected reading of

-10.5 dB.

13. Subtract the Corrected Insertion Loss (step 10) from the power meter Reading (step 12) and record this value as TR Entry 10-l in the performance test record. The CAL OUT should be

-20 dBm f0.4 dB.

CAL OUT Power = Power Meter Reading - Corrected Insertion Loss

Example: If the Corrected Insertion Loss is -10.0 dB, and the measuring receiver reading is -30 dB, then -30 dB - (-10.0 dB) = -20 dB

Option 001 only:

The CAL OUT power measured on 75 62 instruments will be the same as

50 D instruments. To convert from dBm to dBmV use the following equation. Record this value as TR Entry 10-l in the performance test record.

Example: -20 + 48.75 = 28.75.

dBmV = dBm + 48.75 dB

11. Frequency Response

The output of the synthesized sweeper is fed through a power splitter to a power sensor and the spectrum analyzer. The synthesized sweeper’s power level is adjusted at 300 MHz to place the displayed signal at the spectrum analyzer center horizontal graticule line. The measuring receiver, used as a power meter, is placed in RATIO mode. At each new sweeper frequency and spectrum analyzer center frequency setting, the sweeper’s power level is adjusted to place the signal at the center horizontal graticule line. The measuring receiver displays the inverse of the frequency response relative to 300 MHz (CAL OUT frequency).

Testing the flatness of Option 001, INPUT 75 61, is accomplished by first characterizing the system flatness.

The related adjustment for this procedure is the “Frequency Response Error Correction.”

A synthesized source and the spectrum analyzer are set to the same frequency and the amplitude of the source is set to -10 dBm. A marker-amplitude reference is set on the analyzer. The source is then tuned to several different frequencies which should generate image responses. At each source frequency, the source amplitude is set to -10 dBm and the amplitude of the response, if any, is measured using the spectrum analyzer marker function.

The marker-amplitude difference is then compared to the specification.

There are no related adjustment procedures for this performance test.

13. Spurious Response

This test is performed in two parts. The first part measures second-harmonic distortion; the second part measures third-order intermodulation distortion.

To test second harmonic distortion, a 50 MHz low-pass filter is used to filter the source output, ensuring that harmonics read by the spectrum analyzer are internally generated and not coming from the source. To measure the distortion products, the power at the mixer is set 25 dB higher than specified. New test limits have been developed based on this higher power.

With -45 dBm at the input mixer and the distortion products suppressed by 70 dBc, the equivalent Second Order Intercept (SOI) is +25 dBm (-45 dBm + 70 dBc). Therefore, with -20 dBm at the mixer, and the distortion products suppressed by 45 dBc, the equivalent SO1 is also

+25 dBm (-20 dBm + 45 dBc).

For third order intermodulation distortion, two signals are combined in a directional bridge (for isolation) and are applied to the spectrum analyzer input. The power level of the two signals is

8 dB higher than specified, so the distortion products should be suppressed by 16 dB less than specified. In this manner, the equivalent Third Order Intercept (TOI) is measured.

With two -30 dBm signals at the input mixer and the distortion products suppressed by 70 dBc, the equivalent TO1 is +5 dBm (-30 dBm + 70 dBc/B). However, if two -22 dBm signals are present at the input mixer and the distortion products are suppressed by 54 dBc, the equivalent

TO1 is also +5 dBm (-22 dBm + 54 dBc/Z).

Performing the test with a higher power level maintains the measurement integrity while reducing both test time and the dependency upon the source’s noise sideband performance.

There are no related adjustment procedures for this performance test.

It is only necessary to perform “Part 1: Second Harmonic Distortion, 30 MHz” for operation verification.

14. Gain Compression

Gain Compression is measured by applying two signals, separated by 3 MHz. First, the test places a -30 dBm signal at the input of the spectrum analyzer (the spectrum analyzer reference level is also set to -30 dBm). Then, a 0 dBm signal is applied to the spectrum analyzer, overdriving its input. The decrease in the first signal’s amplitude (gain compression) caused by the second signal is the measured gain compression.

There are no related adjustment procedures for this performance test.

This test measures the displayed average noise level within the frequency range specified. The spectrum analyzer input is terminated in 50 0.

The LO feedthrough is used as a frequency reference for these measurements. The test tunes the spectrum analyzer frequency across the band, uses the marker to locate the frequency with the highest response, and then reads the average noise in zero span.

To reduce measurement uncertainty due to input attenuator switching and resolution bandwidth switching, a reference level offset is added. The CAL OUT signal is used as the amplitude reference for determining the amount of offset required. The offset is removed at the end of the test by pressing [PRESETJ

17. Absolute Amplitude, Vernier, and Power Sweep Accuracy

This procedure is only for spectrum analyzers equipped with Option 010 or 011.

The tracking generator output is connected to the spectrum analyzer input and the tracking is adjusted at 300 MHz for a maximum signal level. A calibrated power sensor is then connected to the tracking generator output to measure the power level at 300 MHz.

The measuring receiver is then set for RATIO mode so that future power level readings are in dB relative to the power level at -10 dBm (Option 011: + 38.8 dBmV). The output power level setting is decreased in 1 dB steps and the power level is measured at each step. The difference between ideal and actual power levels is calculated at each step.

Since a power sweep is accomplished by stepping through the vernier settings, the peak-to-peak variation of the vernier accuracy is equal to the power sweep accuracy.

The related adjustment for this procedure is the “Modulator Offset and Gain Adjustment.”

This procedure is only for spectrum analyzers equipped with Option 010 or 011.

The tracking generator output is connected to the spectrum analyzer input and the tracking is adjusted at 300 MHz for a maximum signal level. The tracking generator output is then connected to the input of a microwave spectrum analyzer. The tracking generator is set to several different output frequencies.

For each output frequency, several sweeps are taken on the microwave spectrum analyzer over different frequency spans and the highest displayed spurious response is measured in each span. Responses at the fundamental frequency of the tracking generator output or their harmonics are ignored. The amplitude of the highest spurious response is recorded.

There are no related adjustment procedures for this performance test.

14. Press (SINGLE) on the microwave spectrum analyzer and wait for the sweep to finish. Press

CPEAK SEARCH).

15. Verify that the marked signal is not the fundamental or a harmonic of the fundamental as follows: a. Divide the marker frequency by the fundamental frequency (the spectrum analyzer

CENTER FREQ setting). For example, if the marker frequency is 30.3 MHz and the fundamental frequency is 10 MHz, dividing 30.3 MHz by 10 MHz yields 3.03.

b. Round the number calculated in step a the nearest whole number. In the example above, 3.03 should be rounded to 3.

c. Multiply the fundamental frequency by the number calculated in step b. Following the example, multiplying 10 MHz by 3 yields 30 MHz.

d. Calculate the difference between the marker frequency and the frequency calculated in step c above. Continuing the example, the difference would be 300 kHz.

e. Due to span accuracy uncertainties in the microwave spectrum analyzer and center frequency uncertainties in the spectrum analyzer, the marker frequency might not equal the actual frequency. Given the marker frequency, check if the difference calculated in step d is within the appropriate tolerance:

For marker frequencies ~55 MHz, tolerance = ±750 kHz

For marker frequencies >55 MHz, tolerance = f10 MHz f. If the difference in step d is within the indicated tolerance, the signal in question is the fundamental signal (if the number in step b = 1) or a harmonic of the fundamental (if the number in step b >l). This response should be ignored.

16. Verify that the marked signal is a true response and not a random noise peak by pressing c-1 to trigger a new sweep and press

(

PEAK SEARCH

].

A true response will remain at the same frequency and amplitude on successive sweeps but a noise peak will not.

17. If the marked signal is either the fundamental or a harmonic of the fundamental (see step 15) or a noise peak (see step 16), move the marker to the next highest signal by pressing

ml, [

PEAK SEARCH

).

Continue with step 19.

18. If the marked signal is not the fundamental or a harmonic of the fundamental (see step

15) and is a true response (see step 16), calculate the difference between the amplitude of marked signal and the Fundamental Amplitude as listed in ‘Iable l-22.

For example, if the Fundamental Amplitude for a fundamental frequency of 10 MHz is

+ 1.2 dBm and the marker amplitude is -40.8 dBm, the difference is -42 dBc.

Record this difference as the Non-Harmonic Response Amplitude for the appropriate spectrum analyzer CENTER FREQ and microwave spectrum analyzer START and STOP

FREQ settings in YIhble l-23.

Non-Harmonic Amplitude = Marker Amplitude - Fundamental Amplitude

19. If a true non-harmonic spurious response is not found, record “NOISE” as the

Non-Harmonic Response Amplitude in Table l-23 for the appropriate spectrum analyzer

CENTER FREQ and microwave spectrum analyzer START and STOP FREQ settings.

Returning the Spectrum Analyzer for Service

Use the information in this section if it is necessary to return the spectrum analyzer to

Hewlett-Packard.

Package the spectrum analyzer for shipment

Use the following steps to package the spectrum analyzer for shipment to Hewlett-Packard for service:

1. Fill in a service tag (available in the HP 8590 Series Spectrum Anulyzer User’s Gwicle) and attach it to the instrument. Please be as specific as possible about the nature of the problem. Send a copy of any or all of the following information: n

Any error messages that appeared on the spectrum analyzer display.

n

A completed Performance Test record. (Located in Chapter 1 of this guide.) n

Any other specific data on the performance of the spectrum analyzer.

Caution Spectrum analyzer damage can result from using packaging materials other than those specified. Never use styrene pellets in any shape as packaging materials. They do not adequately cushion the instrument or prevent it from shifting in the carton. Styrene pellets cause equipment damage by generating static electricity and by lodging in the spectrum analyzer fan.

2. Use the original packaging materials (see Figure 3-1) or a strong shipping container that is made of double-walled, corrugated cardboard with 159 kg (350 lb) bursting strength. The carton must be both large enough and strong enough to accommodate the spectrum analyzer and allow at least 3 to 4 inches on all sides of the spectrum analyzer for packing material.

3. If you have a front-panel cover, install it on the instrument; if not, protect the front panel with cardboard.

4. Surround the instrument with at least 3 to 4 inches of packing material, or enough to prevent the instrument from moving in the carton. If packing foam is not available, the best alternative is SD-240 Air CapTM from Sealed Air Corporation (Commerce, CA 90001).

Air Cap looks like a plastic sheet covered with l-1/4 inch air-filled bubbles. Use the pink Air

Cap to reduce static electricity. Wrap the instrument several times in the material to both protect the instrument and prevent it from moving in the carton.

5. Seal the shipping container securely with strong nylon adhesive tape.

6. Mark the shipping container “FRAGILE, HANDLE WITH CARE” to ensure careful handling.

7. Retain copies of all shipping papers.

Use the following illustration and table to help you package a tracking source for shipment.
