The Digital satellite finder is a professional, quality made instrument for setting and aligning a satellite dish to any satellite. According to parameters of the satellite, you can set and align a satellite dish very accurately, quickly and conveniently. Features as follows: 1. Graphic user interface, Designed to be very easy to use. 2. With Fast and easy menu structures. It can calculate Azimuth, Elevation and Polarization automatically according to local longitude and latitude and show these details on the colour LCD display. 3. It can communicate with your PC through the serial port and you can update new satellite parameters conveniently. 4. With A Large memory capacity you can pre-store 80 satellite!íÑsparameters and 40 measurement records. 5. With the high quality LCD screen you can watch the TV channel from the satellite you are testing. This is giving the ultimate verification that the satellite you are looking at is the correct one.
The Signal Analysis Meter is a full-featured handheld signal performance meter providing a complete signal test system in easy-to-carry protective case. Signal Analysis Meter allows choice of 4 pre-programmed user-selectable band plans accessed via keypad entry for easy measurement of broadcast, CATV, CATV/HRC, and SUB/VHF channels. Direct-entry channel or frequency tuning selections provide maximum flexibility in head-ends and distribution networks that employ narrow digital signals or non-standard frequency applications. The meter displays instantaneous digital signal levels when testing digital carrier levels. The large LCD screen displays signal level as a bar-graph with digital numeric readout. This backlit display provides screen illumination in dimly lit work-spaces, allowing behind rack and night meter operation. Signal Analysis Meter enables testing of carrier-to-noise, multiple channels, and full, reduced, and single band scan for complete testing flexibility. The meterí»s functions include not only signal measurement when AC/DC voltage is present under test, but, when selected, voltage-level display. Full-channel operation 5-870MHZ Frequency Range 4-keypad channel plans (TV, CATV/STD,CATV/HRC,SUB/VHF) enable quick switching between sources Single keypad frequency or channel selection provides compatibility with channel, data, and other narrow bandwidth carriers Full spectrum-analyzer scan provides display of up to 100 channels simultaneously Carrier-to-noise testing provides accurate testing of system performance anywhere in the head-end or distribution system Large easy-to-read backlit Graphic LCD display provides quick-glance signal reference even in dimly lit work environments AC/DC voltage readings and compatibility allow measurements through input connector, enabling signal and voltage measurements when voltage is present in tested signal without costly adapters 8-Hour rechargeable NiMH batteries provide cost savings Automatic power shut-off feature extends time between recharges Bright orange high impact plastic housing and soft leatherette-vinyl protective case with belt clip included 8 pieces in one carton
S8808 CATV Signal level meter is a measuring instrument especially designed for CATV technician. It is complete digital display with clear and correct reading and the using of microprocessor makes it has high capacity, more accurate and more flexible to operate. Meanwhile it has the character of small size, lightweight, and easy carrying, so it is more suitable to be used outside and fixing TV. Technical information (All the technical indexes below are under indoor temperature 25íµ) Frequency range: 48MHZ-870MHZ Frequency resolution ratio: 50KHZ Measured band width: 280KHZ Level Measurement Measurement range: 30dBuV-120dBuV Measurement accuracy:
The product, which newly researched and developed, is the integrative high-tech measuring instrument for the transformation of CATV .The main function is to measure QAM digital signal and analogue signal. The measurable item includes: power measurement , MER measurement , BER measurement , constellation ,channel measurement, tilt measurement, scan measurement, spectrum measurement, carrier noise ratio measurement, and rail voltage measurement. Make the corresponding choice according to the different occasion. The inside process chip adopts the extensive integrated microprocessor which is special to the most advanced tester in the world at present. It has many characteristics such as: the complete function, the fast processing speed, the low static power consumption, small and the high dependability. The peripheral circuit uses its special integrated package design according to corresponding function. The appearance adopts the human mechanics principle, it can be held firmly by single-hand and operated.
