1.0 INTRODUCTION

An antenna drive subsystem test was performed on the EOS AMSU-AI_ S/N 202

instrument. The objective of the test was to demonstrate compliance with applicable

paragraphs of AMSU-A specifications S-480-80. Tests were conducted at both the

subassembly and instrument level.

2.0 SUMMARY

The antenna drive subsystem of the EOS AMSU-A1, S/N 202, P/N 1356008-1, completed

acceptance testing per AES Test Procedure AE-26002/1C. The test included: Scan

Motion and Jitter, Noisy Bus Peak Current and Rise Time, Resolver Reading and Position

Error, Gain/Phase Margin, and Operational Gain Margin.

The drive motors and electronic circuitry were also tested at the component level. The

drive motor test includes: Starting Torque Test, Motor Commutation Test, Resolver

Operation/No-Load Speed Test, and Random Vibration. The electronic circuitry was

tested at the Circuit Card Assembly (CCA) level of production; each test exercised all

circuit functions. The transistor assembly was tested during the W3 cable assembly

(1356424-1) test. Refer to Figure 1 for test flow.

3.0 TEST CONFIGURATION

The Reflector Drive Assembly Tests confirm the operability of the motor under test. The

test configuration includes, the motor, motor shaft, bearings, and a supporting housing.

The Circuit Card Assembly (CCA) Tests confirm the operability of each CCA. Each test

includes the CCA under test, electronic test fixtures, and the necessary loads.

A segment of the Signal Processor Tests ensures the scan drive electronics are

functioning properly prior to it's assembly into the instrument. The test configurationincludes:

• Timing and Control CCA• Scan Control Interface CCA

• Mux/Relay Control CCA• Interface Converter CCA

• Resolver Data Isolator CCA

• R/D Converter CCA

• Motor Driver CCA

• Test fixture and cabling to simulate the 1553 bus interface

• Test fixture and cabling to interrogate and analyze positional data• Test motor and inertia wheel

The Transistor Assembly Test verifies the correct wiring of the transistor assembly and

associated cabling. Test configuration includes the CKT 1000 (continuity and Hi-Pot

tester), and test fixtures.

The Antenna Drive Subsystem Tests:

• Are configured with the same motor control CCA's used in the signal processor

test, interconnecting wiring, the power transistor assembly, and the drive

assembly with reflector.

• The antenna drive subsystem components were all installed in the instrument

when the subsystem test was performed.

• DC power for the motor control circuit cards was provided by a DC/DC converter

simulator P/N: 1359322-1. The simulator operates on 120VAC facility supplied

Page 6: Integrated Advanced Microwave Sounding Unit-A (AMSU-A

power. The power for the reflector motor drive circuits however was provided

directly by the STE Noisy Bus power supply.

4.0 TEST SETUP

The antenna drive subsystem tests are performed during system integration. During

system integration testing, the instrument is proven electrically safe via ground isolation,

and power distribution checks. Next, the communication link is exercised to ensure

commands are received and interpreted correctly. The Antenna Drive Subsystem Test is

then performed.

Subsystem Component SfN Designations

During preliminary testing of these components (in preparation for the antenna drive

subsystem test), several component failures occurred. The component failures and system

related dispositions are listed below:

• Reflector Drive Motor (A1-D - during assembly test, it was noted that

the motor was binding. It was determined that excessive bonding

material was used and it flowed onto the shaft. The shaft was cleaning

Page 7: Integrated Advanced Microwave Sounding Unit-A (AMSU-A

Report 11183

July 1998

and tests showed a positive resolution. The process planning wasaltered to reduce the risks of recurrence.

Reflector Drive Motor (.41-2) - during vibration testing the resonant

frequency shifted. The motor was disassembled but anomalies were

found. Electronic tests found nothing abnormal either. The motor was

successfully re-vibrated without failure.

All other components designated for use in the EOS AMSU-A1 instrument (pertaining to

the scan drive circuitry) passed on the first time through component testing.

5.1 REFLECTOR DRIVE ASSEMBLIES

The tests performed on this unit are: Starting Torque Test, Motor Commutation Test,

Resolver Operation/No-Load Speed Test, and Random Vibration. The Motor

Commutation and Resolver Operation tests are performed both pre and post-vibration.

Starting Torque

The starting torque test is performed on the rotating segment of the drive assembly to

verify the torque associated with bearing friction. Reflector drive assembly (F04) failed

the starting torque test at ambient temperature. The motor was binding due to a process

error. Bonding material flowed onto the motor shaft preventing it from turning with

voltage applied. The shaft was cleaned and re-tested. The reflector drive assembly (F04)

then passed the starting torque test at ambient temperature as well as at the colder

plateaus.

Reflector drive assembly (F05) passed the starting torque test at ambient temperature as

well as at the colder plateaus first time through testing.

Motor Commutation Test

This test is performed to determine the commutation characteristics of the motor under

test. Both reflector drive assemblies (F04 and F05) passed the motor commutation test

both pre- and post-vibration tests without incident.

Resolver Operation/No-Load Speed Test

This test is performed to verify resolver operation as well as speed characteristics and

back electromotive force of the motor. Both reflector drive assemblies (F04 and F05)

passed the resolver operation/no-load speed test both pre- and post-vibration testswithout incident.

Report 11183July 1998

Random Vibration

Reflector drive assembly (F04) passed vibration testing first time through. The motor

assembly also passed the pre- and post-vibration electronic tests as well as the post-

vibration visual inspection without incident.

Reflector drive assembly (F05) experienced a significant change in resonant frequency at

the random vibration, -6db level. The motor was disassembled, but no anomalies were

found. The motor was successfully re-tested and returned to vibration testing. The motor

was re-vibrated without incident. The reflector drive assembly passed the pre- and post-

vibration electronic tests as well as the post-vibration visual inspection without incident.

5.2 CIRCUIT CARD ASSEMBLIES

Test procedures were prepared for each motor control circuit card; document revision

status is controlled by reference in the shop order. The cards were individually tested to

the procedures and results were recorded on data sheets found in Appendix A. The

following list indexes the CCA Test Data Sheets:

• Appendix A1 ............. Resolver Data Isolator Assembly (AI-1)

• Appendix A2 ............. Resolver Data Isolator Assembly (A1-2)

• Appendix A3 ............. Interface Converter Assembly (AI-1)

• Appendix A4 ............. Interface Converter Assembly (A 1-2)

• Appendix A5 ............. Motor Driver Assembly (AI-1)

• Appendix A6 ............. Motor Driver Assembly (A1-2)

Appendix A 7 ............. R/D Converter/Oscillator Assembly (A 1-1)

Appendix A8 ............. R/D Converter/Oscillator Assembly (A1-2)

All circuit card assemblies passed testing the first time through. The assembly build shop

orders contain the part number and accept tag record the of test and select resistors.

5.3 SIGNAL PROCESSOR

For the first time, the entire antenna drive motor electronics is mated together. The test

instrumentation commands and interrogates the electronics during this segment of testing.

The instrumentation sends position commands to the Interface Converter CCA. The

Interface Converter D/A's the command and provides inputs to the Motor Driver CCA.

The test motor (instrumentation) responds to the drive signal and feeds back positional

data via resolver outputs. The instrumentation then interrogates the Resolver Data

Isolator CCA for position data. A comparison is made in the instrumentation between the

Page 9: Integrated Advanced Microwave Sounding Unit-A (AMSU-A

Report 11183July 1998

position command sent and the actual position received. The pass/fail indication is

presented to the operator for test data sheet recording.

The signal processor assembly (F01) passed all scan drive tests.

5.4 TRANSISTOR ASSEMBLY

All transistor assemblies are tested along with their respective W3 cable. The cable is

continuity, then hi-pot tested prior to attaching the transistor circuitry. Each transistor

pair is exercised validating the turn on voltage, current drawn, and cable wiring as well.

The W3 cable assembly was placed on an Inspection Report (IR# 101780) for cracks in a

connector. The connector was subsequently repair by applying .003 inch minimum 2216

epoxy over the cracks. This action precludes the separation of any connector moldingmaterial.

The W3 cable and transistor assembly underwent component testing and passed without

incident.

5.5 ANTENNA SUBSYSTEM DRIVE TESTS

The antenna drive motor electronics mates with the instrument microprocessor for the

first time during this segment of testing. The microprocessor sends position commands

from the memory CCA to the Interface Converter CCA. The Interface Converter D/A's

the command and provides inputs to the Motor Driver CCA. The Reflector Drive Motor

responds to the drive signals and feeds back positional data via the resolver outputs. The

microprocessor then interrogates the Resolver Data Isolator CCA for position data.. The

microprocessor in turn communicates with the 1553 interface which subsequently relays

positional data to the STE.

During other segments of the test, positional data is monitored via a potentiometer

attached to the shaft of each reflector drive assembly. This provides scan characteristic

information in regard to overshoot, jitter, and beam position transition timing for each

motor assembly.

The remaining paragraphs in this section discuss tests that ensures the instrument

complies with specific operating parameters. Prior to conducting these tests there is a

series of preliminary checks that are run to select component values that customize the

operating parameters of each motor. These checks perform the following functions:

Page 10: Integrated Advanced Microwave Sounding Unit-A (AMSU-A

Report11183July1998

• Program"onboard"memorywith BeamPositionPointingAnglesfor eachreflectordriveassembly

• Adjustfor peakMotor CurrentLimits onbothAI-1 andA1-2motor drive circuits• ObservePreliminaryScanDynamicsonbothAI-1 andA1-2motor drive circuits• IdentifyMechanicalResonantFrequenciesof eachreflectordrive assembly

Beam Position Pointing Angles are calculated from Nadir pointing direction which is

determined on the antenna range. The instrument's EPROMs (EPROMs for testing;

PROMs for final configuration) are programmed to reflect the position commands. The

initial programming may require fine tuning; fine tuning is determined during the

remaining segments of the test procedure.

Motor Current Limits were adjusted, via selecting "test and select" resistors, to comply

with the specification requirement; less than 1 amp peak current.

Preliminary Scan Dynamics looked good; transition times, overshoot and jitter were all

acceptable at the sampled pointing directions (5).

The Mechanical Resonant Frequencies were identified; notch filters were calculated and

installed to compensate for these resonant frequencies.

5.5.1 SCAN MOTION AND JITTER

In this test, the antenna position was measured in a series of five 8-sec full scans. The

measurement was made with a 1-turn test potentiometer temporarily affixed to the rear

end of the motor shaft. A Dynamic Signal Analyzer (DSA) was connected to the pot

wiper to record the antenna position data. Five scans of each AI-1 and A1-2 were

captured and stored on the AMSU-A1 Test Data File disc. One representative waveform

from each subassembly is presented in Appendix B1 (AI-1) and Appendix B34 (A1-2).

Each 3.33 degrees scene step was expanded and checked for both a 35 msec max step

time, and a 165 msec integration period. Expanded waveforms were plotted and are

presented in Appendix B2 thru B31 for the AI-1 subassembly and Appendix B35 thru

B64 for the A1-2 subassembly. All of the scene steps meet the step response requirement

for transition time, overshoot, and jitter.

Slew periods to the cold and warm calibration stations were measured and met

requirements. A time of 0.21 sec is allocated for the 35.0 degree slew to cold cal, and

0.40 sec for the 96.67 degree slew to warm cal. Calibration station jitter was less than the

+ 5 % maximum permitted. Expanded waveforms for each subassembly were plotted and

are presented in Appendix B32 and B33 (AI-1) and Appendix B65 and B66 (A1-2). Thewaveforms are also stored on the AMSU-A1 Test Data File disc. The test data sheets are

presented in Appendix B67 (AI-1) and B68 (A1-2).

Report 11183

July 1998

5.5.2 NOISY BUS PEAK CURRENT AND RISE TIME

The Noisy pulse load bus peak current and the rate of change of current were measured.

The peak cu_ent must be less than 1A at any beam position along the scan. Peak current

along the scan is .940A. The current rate of change while transitioning from one beam

position to the next (including the transition to the cold calibration and warm calibration

targets) should be greater than 35 microseconds. A random 3.33 ° step was selected; the

transition to the next step was 1.6 ms. The transition to the warm cal position start and

stop was significantly longer than the required 35 ms; 1.95 and 1.56 ms respectively.

The peak bus current was measured across the entire scan and met the requirement. The

full scan waveform was plotted and is presented in Appendix C 1. The waveform is also

stored on the AMSU-A1 Test Data File disc. The test data sheet is presented in Appendix

C2.

5.5.3 RESOLVER READING AND POSITION ERROR

The 14-bit command position word is stored in the "on-board" memory and is read to the

motor drive circuitry under microprocessor program control. The microprocessor also

reads the resolver output at each of the thirty scene stations, and at the cold and warm

calibration positions. The readings are made at the start of integration (LOOK 1), and

halfway into the integration period (LOOK 2). The resolver data is sent to the 1553 bus

interface for subsequent transmission to the STE.

The purpose of this portion of the test is to demonstrate that the antenna is meeting beam

pointing requirements.

If the antenna is out of the pointing tolerance of> + 10 counts at LOOK 1 or > + 5 counts

at LOOK 2, the EPROM is reprogrammed to bring the pointing direction to within the

prescribe tolerances. A copy of the STE computer print out showing the pointing

direction is shown in Figure 2 for the AI-1 subassembly and Figure 3 for the A1-2

subassembly.

5.5.4 GAIN/PHASE MARGIN

11

Page 13: Integrated Advanced Microwave Sounding Unit-A (AMSU-A

Report 11183July 1998

A gain/phase margin test was performed on the antenna drive subsystem. The test was

performed by obtaining a Bode plot of the control loop and measuring the gain at 180 °

phase differential and the phase margin at the 0db crossover point.

The Dynamic Signal Analyzer (DSA) was used to make the measurement operating in the

swept sine mode. Three separate Bode plots were made on the antenna and the gain and

phase margins were determined from each plot. The gain margin measured was 9.55 db

(average of three) for the AI-1 subsystem and 9.26 db (average of three) for the A1-2

subsystem. The phase margin measured was 71.1 ° (average of three) for the AI-1

subsystem and 70.0 ° (average of three) for the A1-2 subsystem. These margins exceed

the specification requirements of 9.2 db and 25 degrees and therefore are acceptable. The

three Bode waveforms were plotted and are presented in Appendix D 1 thru D3 for the

AI-1 subsystem and Appendix D4 thru D6 for the A1-2 subsystem. The waveforms are

also stored on the AMSU-A1 Test Data File disc. The test data sheets are presented in

Appendix D7and D8 for AI-1 and A1-2 respectively.

5.5.5 OPERATIONAL GAIN MARGIN

An operational gain margin test was performed on the instrument three times. This test

consists of increasing the gain of the control loop until oscillation occurs. The gain

increase and frequency of oscillation are measured. An increase in gain greater than 8 db

is required; the frequency of oscillation is an observation.

A 50K pot was connected in series with the R58 feedback resistor on amplifier AR8. The

resistance of the test pot was slowly added to the feedback resistor while observing thereflector for oscillations.

The reflector begins to produce an audible sound as gain is increased. The followingadded resistance values are calculated to have the following gain margins for the A1-1

and A1-2 subsystems:
