Section VI. TEST FIXTURES 6A1 THROUGH 12A1

3-51. General

Seven test fixtures form part of the Test Facility Set

ANIGRM-95(V)2. Each test fixture is contained in a separate case which is for protection only. Each fixture is a mechanical test stand used to test and aline the appropriate modules of Radio Sets AN/GRC-103(V)1, 2,

3 and 4.

3-52. Test Fixture, Frequency Multiplier

TS-3824/GRM-95(V)2

(fig. 3-8)

The AUT is placed in position against the three locating posts and locked in position by the retaining clamp. The two holes in the baseplate are to facilitate attachment of test cables to connectors J 1 and J2 of the AUT. The drive shaft of the AUT is attached to the flexible drive shaft of the mechanical drive assembly by two retaining screws. The initial setting of the drive shafts is achieved by turning the locking knob counterclockwise.

Loosening the locking knob in this manner allows the tuning shaft control knob to rotate the shaft of the AUT in- dependently of the calibrated dial control knob. The tuning shaft control knob is turned to preset the AUT to a position corresponding to a desired frequency. The locking detent is pressed in and the calibrated dial control knob tuned to set the calibrated dial to the same preset frequency. Releasing the locking detent keeps the calibrated dial locked in the preset position. The locking knob is then turned clockwise locking the two control knobs together. With the two control knobs locked together, adjustment of the calibrated dial by the tuning shaft control knob can be achieved by releasing the locking detent. Any subsequent adjustment of the tuning shaft control knob will now give a corresponding adjustment to the AUT through the drive shafts.

Adjustments to the AUT can be made from all exposed sides. The side facing the baseplate of the test fixture has no adjustment points.

The AUT is placed in position against the retaining plate taking care to engage the two pins on the AUT into the two holes in the retaining plate. The two spacers are used to locate and stabilize the AUT. The AUT is then locked in position by the retaining clamp. The hole in the baseplate is to facilitate attachment of the test cables to the AUT. The shaft of the AUT is connected to the flexible drive shaft of the test fixture by two retaining screws. The initial setting of the drive shafts is achieved by turning the locking knob counterclockwise.

Units 37A1 and 38A1 are similarly mounted on the test fixture so that the respective connectors engage J1 of the test fixture. The tuning shaft of each unit is coupled to a different drive shaft. Both shafts are driven by a common tuning control knob. Unit 38A1 has a plastic drive wheel with teeth which engage two pins on the drive disk at the end of the flexible shaft. Unit 37A1 has a flexible drive shaft with a coupling which engages the fixed drive shaft of the test fixture. With the unit under test in position, the connector on the AUT mates with the connector J1 on the Last fixture. Connector J1 is parallel wired to J2 which provides the interface for dc supplies and control signal, from the test facility, to the unit under test. The, tuning control knob drives both the

3-28

flexible drive shaft and the fixed drive shaft simultaneously by a drive chain. A four digit counter is also activated by the tuning control knob by a clutch assembly on the fixed drive shaft. The counter records the number of revolutions of the control shafts. The counter can be adjusted in- dependently of the tuning control knob by means of the counter control knob which is geared to a slipping clutch. Setting the counter is accomplished by holding the tuning control knob firmly and turning the counter control knob until the desired

TM 11-6625-1696-12

setting is registered on the counter. The positions of the drive shafts are not disturbed during this operation. The counter is bidirectional in that it can be operated on either side of zero. Amplifier frequency multiplier 38A1 is driven in a positive direction and the counter reading is positive. Amplifier frequency multiplier 37A1 is driven in the reverse direction and the counter reading is negative. A hole is provided in the baseplate of the test fixture so that the variable capacitor in unit 37A1 can be observed during testing.

In order to place an AUT in position on the test fixture, the gage arm must be swiveled from its normal operating position. The gage arm is secured in position by a retaing clamp which in turn is held in position by a thumb screw. Once the thumb screw is loosened, the retaining clamp is repositioned to free the gage arm which can then be moved. The assembly to be tested is then positioned on the test fixture so that the tuning shaft of the assembly is coupled to the flexible shaft of the test fixture. Locating pins on the AUT are also coupled to holes in the test fixture. The mounted assembly is held in position by the two securing screws,

3-30

TM 11-6625-1696-12

and the gage arm is lowered onto the AUT engaging the tuning plunger of the assembly with one of three calibrated positions in the gage. Each position in the gage arm corresponds to a frequency. The frequencies, which are 1030 MHz, 880 MHz and 725 MHz, are stenciled on the gage arm above their respective position. The input and output cables of the AUT are connected to the right-angle connectors which are provided to facilitate the connection of test cables to the

AUT. After testing at one frequency, the gage arm must be lifted in order to reset the AUT to the next position.

CAUTION

Do not lift or remove the test fixture from the case by lifting the fixture with the gage arm.

a. The swiveled mounting block of the test fixture provides support to the rear of an assembly under test, as well as directs air over the output tubes. The swiveled mounting block is secured by a locking screw.

The screw is loosened to allow the mounting block to swivel on a pivot to facilitate the mounting on an AUT.

b. The AUT is positioned on the test fixture so that the two locating pins on the unit engage holes in the

retaining block adjacent to J3 (fig. 3-12), and the tuning

mechanism meshes with the flexible shaft disk. The flexible shaft disk is connected to the tuning control through a chain driven tuning mechanism. The AUT is secured to the retaining block by a knurled thumb retaining screw. The swiveled mounting block is swiveled into position to secure the rear of the AUT.

The swiveled mounting block also contains an air hose clamp. The air hose clamp has a corrugated inside surface which prevents the air hose from being accidently disconnected. The air hose is a component of

3-31

the Accessory Kit, Test MK-1985(V) l/GRM-95(V)2. Air is supplied to the test fixture from the transmitter test facility. When an assembly is mounted on the test fixture and the correct air pressure is being supplied, the contacts of the pressure differential switch will close and complete a 600 volt interlock circuit through connector

J1 pins 8 and 9. Closing the interlock circuit permits the

600 volt supply in the transmitter test facility to be switched on and fed to the output tubes of the AUT.

c. Two holes (V1 and V2) are provided in the swiveled mounting block to facilitate adjustment of the

TM 11-6625-1696-12

position of the power tubes in the cavities. Three test points J3, J4 and J5, located on the base of the test fixture, are provided to allow resistance measurements of the thermistor mounted on the tubes in the AUT. The direct drive tuning mechanism is controlled by the control knob which also drives the counter. The counter operates in the range from 0.8 to 60.4 MHz and locks at both ends. The counter is calibrated in increments of

0.02 MHz so that the RF amplifier can be checked at any designated point.

The transmitter frequency multiplier 40A2 (245-800491-

000) is mounted on the same side of the test fixture as the counter. When the AUT is mounted on the test fixture, the plug of the AUT is automatically engaged with J1 of the test fixture. J1 is parallel wired to J2 through which operating voltages to the AUT are supplied. J2 is connected to the test facility by a special purpose cable 2W5 (457-573). This cable assembly is located in the

TM 11-6625-1696-12

transmitter test facility. The tuning mechanism drive locks at the counter setting of 000 and 220 to prevent overdrive. Frequency multiplier 39A3 (245-800487-000) is similarly mounted on the test fixture except that this unit is mounted on the opposite side of the gear assembly to that of the counter. When mounted, the receiver frequency multiplier 39A3 automatically engages J4 which is parallel wired to J3, through which operating voltages are supplied to the 39A3 assembly under test.

The test fixture is used to test bandpass filters 39FL1,

39FL2, and 40FL1. These filters are mounted vertically and engage the drive shaft and disk on one side of the test fixture. The same test fixture is used to test bandpass filter 39FL3 which is also mounted vertically.

This unit engages the bevel gear on the opposite side of the test fixture. The AUT is held in position by retaining screws located under the baseplate of the test fixture.

The tuning mechanism drive locks at the counter settings of 000 and 0985 by locking washers on the main drive shaft. One turn of the control knob produces approximately three turns of the drive shaft.

This fine document...

Was brought to you by me:

Liberated Manuals -- free army and government manuals

Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly available information, slap “watermarks” and other junk on it, and sell it.

Those masters of search engine manipulation make sure that their sites that sell free information, come up first in search engines. They did not create it...

They did not even scan it... Why should they get your money? Why are not letting you give those free manuals to your friends?

I am setting this document FREE. This document was made by the US

Government and is NOT protected by Copyright. Feel free to share, republish, sell and so on.

I am not asking you for donations, fees or handouts. If you can, please provide a link to liberatedmanuals.com, so that free manuals come up first in search engines:
