30、.b. rf pulse. The internal pulsing system will operate either in a free-running condition or in synchronism with an external synchronizing voltage. An internal delay circuit is provided so that the time-phase of the pulse modula- tion can be varied over a range from 3 to 300 micro- seconds. Frequenc

31、y modulation of Signal Generator TS-403/U occurs at the power line frequency. Controls for adjust- ing the deviation and phase of the modulation are pro- vided on the front panel. Maximum deviation is of the order of one-half of one percent of the carrier fre- quency. In addition to its rf output, S

32、ignal Generator TS-403/U also generates two separate video pulses for external use. One video pulse is coincident with the start of the ex- ternal synchronizing voltage, while the second video pulse is coincident with the start of the rf output pulse. This second video pulse is therefore delayable o

33、ver a range from 3 to 300 microseconds concurrent with the rf pulse. Further information on the electrical characteristics of Signal Generator TS-403/U is given in Section V of this handbook under table 5-1, “General Characteristics.” 6. GENERAL DESCRIPTION. Signal Generator TS-403/U is unusual amon

34、g equip- ments in its frequency range in that it is directly cali- brated in output frequency as well as in output power. The wide frequency range is covered in one continuous band and output frequency is selected by means of a single calibrated tuning dial. The output power is also selected by mean

35、s of a single calibrated dial. Thus, no charts or critical multiple adjustments are necessary either for selecting output frequency or power. The circuit which generates the UHF frequencies con- sists of a type JAN-2K28 reflex klystron operating with an external resonant cavity whose electrical leng

36、th is ad- justed by movable shorting bars. The repeller voltage for the klystron is automatically tracked with the setting of the cavity shorting bars so that a single control deter- mines the position of the shorting bar and the magnitude of the repeller voltage. This system makes possible the cali

37、bration of the tuning dial directly in frequency, an unusual feature at these frequencies. A standby heater is provided in the instrument for the purpose of maintaining the temperature within the in- strument case higher than the ambient temperature during periods of intermittent use. This feature i

38、s designed to prevent the frequent condensation of moisture within the instrument case. Physically, the signal generator is relatively small in size, being only 17 inches long x 14 inches high x 13 inches deep. The front panel is provided with stainless steel guard rail type handles. Aluminum mounti

39、ng feet are provided on both the bottom and back sides of the instrument case. Structural parts, including the front panel and the in- strument case, are made of aluminum alloy. The chassis of the instrument is mounted vertically, parallel to the front panel. Small components such as composition re-

40、 sistors and mica capacitors are, for the most part, mounted on phenolic terminal boards. The instrument case can be removed by loosening the eight captive thumb screws at the outer edges of the front panel and pulling the panel away from the instru- ment case. Ventilation is provided by louvres in

41、the side and back surfaces of the instrument case and by holes in the bot- tom of the case. All openings are covered by wire screen in order to prevent the entry of insects and to minimize rf leakage. 7. TRANSIT CASE Transit Case CY-669/U is provided with Signal Gen- erator TS-403/U and is shown in

42、figure 1-2. This case Figure 1-2.Transit Case CY-669/U is designed to be water-tight and contains space and mounting provisions for the operating spares and acces- sories which are supplied with the instrument and for this handbook (see figure 1-3). The extra RF probe, how- ever, is not contained wi

43、thin the transit case but rather within the instrument case. The transit case is constructed of a special laminated material consisting of balsa wood covered on each side with aluminum sheeting. The cover for the instrument case is provided with a double lip which is filled with sponge rubber. The d

44、ouble lip effects a water-tight seal when the cover for the case is closed. The cover is at- tached to the case by eight trunk-type latches. 8. ACCESSORIES. The accessories supplied with Signal Generator TS- 403/U are shown in figure 1-1. a. Cable CG-92B/U (6) is the rf output cable and con- sists o

45、f approximately six feet of RG-9A/U cable with a UG-2 lB/U plug on each end. b. Cord CG-403/U(82) consists of approximately eight feet of RG-58/U coaxial cable with a UG-88/U 1-2 Figure 1-3.

46、 TS-403/U. c. Cord CX-337/U(6) is provided for connecting the power plug on the instrument to the ac supply. The cord consists of approximately six feet of two-conductor cable with a conventional power plug on one end and a motor body on the opposite end. d. Adapter UG-273/U is provided for adapting

47、 the UHF series of connectors to the BNC series. Three such adapters are provided with each instrument. e. Fuses F-103 to F-105 are provided in the transit case cover for replacing the fuses in the instrument when nec- essary. Five spare fuses are provided, three being located in the transit case an

48、d two in the spare fuse-holders on the front panel of Signal Generator TS-403/U. f. Pilot lamps E-158 to E-160 are also provided in the transit case cover. Three spare lamps are provided for re- placing the lamps in the holders on the panel of the in- strument when necessary. g. RF probe E-145 is lo

49、cated on the back side of the plug on each end. Two of these cords are provided withchassis of the instrument. This assembly is provided as a each instrument. The cords are designed to connect tospare for the monitor RF probe in the instrument. A pro- cedure is incIuded in Section IV of this manual for re- placing the RF probe. 9.
