PINEAPPLE TECHNOLOGY, INC. UTX3KW-A Operating and Service Manual III — TRANSMITTER INSTALLATION III — TRANSMITTER INSTALLATION To ensure long and reliable trouble-free service from the UTX3KW-A transmitter the following steps for installation are recommended. 1. MECHANICAL INSTALLATION: The UTX3KW-A was designed to be installed in a building protected from the weather. The building should have a hard-surface floor such as concrete with a moisture barrier.
PINEAPPLE TECHNOLOGY, INC. UTX3KW-A Operating and Service Manual IV — TRANSMITTER TURN ON PROCEDURE IV— TRANSMITTER TURN ON PROCEDURE Before applying AC Power to the transmitter for initial turn on and check out, the installation should be approved by a qualified broadcast engineer. The turn on procedure that follows is recommended by Pineapple Technology, Inc. engineering staff: 1. Check transmitter load or antenna for proper installation and connection to the transmitter. 2.
PINEAPPLE TECHNOLOGY, INC. UTX3KW-A Operating and Service Manual IV — TRANSMITTER TURN ON PROCEDURE 14. Apply a video signal (1 volt P-P) to the video input terminal. 15. Slowly increase the output level adjustment while watching the RF Output level on the ADP500. When the output gets up to 50% indicated power stop the adjustments. 16. Using the ADP500 reflected power indication check the LOAD reflected power. This should be less that 5% reflected. 17.
PINEAPPLE TECHNOLOGY, INC. UTX3KW-A Operating and Service Manual V — THEORY OF OPERATION V— THEORY OF OPERATION A. INTRODUCTION The UTX3KW-A transmitter was designed to meet or exceed all FCC applicable specifications for TV Broadcast Equipment. Special attention was given to the selection of sub-assemblies and components to achieve maximum reliability and minimum down time. The construction of the UTX3KW-A is BASIC and MODULAR with most components field replaceable.
PINEAPPLE TECHNOLOGY, INC. UTX3KW-A Operating and Service Manual V — THEORY OF OPERATION D. ADP500 & PAS10 PERFORMANCE MONITOR The ADP500 & PAS10 (PERFORMANCE MONITOR) provides the following functions: 1. Monitors FORWARD AND REFLECTED POWER to the antenna and presents it as a percentage of power rating. The transmitter comes set to 100% P-Sync power based on the ratings of the transmitter. 2. Monitors Aural Power as a percentage of P-Sync rating (5-10 % typical) 3.
PINEAPPLE TECHNOLOGY, INC. UTX3KW-A Operating and Service Manual V — THEORY OF OPERATION P RFLD................................................................ Reads PA output power being returned from the load and displayed as a percentage of forward power. Typical reading would be < 5% indicated P AURAL............................................................. Reads the AURAL POWER component as a percentage of forward power. Typical reading would be 10% AUX 1 & AUX 2 .................................
PINEAPPLE TECHNOLOGY, INC. UTX3KW-A Operating and Service Manual V — THEORY OF OPERATION G. DRV100DC-2 DRIVER The output power of the modulator is applied to the input of the DRV100DC-2 driver. This amplifier increases the drive level to that required for the MFA1KW to make rated power. The driver amplifier requires 31 VDC to operate and does not require any tuning or adjustments to change channels. REFER TO SECTION VI.C. (Page 19) FOR SCHEMATIC AND PARTS LIST. H.
PINEAPPLE TECHNOLOGY, INC. UTX3KW-A Operating and Service Manual V — THEORY OF OPERATION K. UC3KW-DC40 COMBINER/DD COUPLER The UC3KW is a 6-way in phase combiner with built in 40 dB dual directional coupler. The combiners are designed for the channel designated for the transmitter. This is a closed unit and cannot be serviced. SEE SECTION VI.G. (Page 38) FOR PARTS LIST L. BPU3KW UHF BAND PASS FILTER This Band Pass filter was designed to meet FCC Certification requirements with minimum loss of RF Power.
