Information

The Sencore FS134 Field Strength Meter is a completely solid state portable instrument designed to identify and measure the frequency and signal strength of FM stations and all VHF and UHF TV stations. Because of the increase in popularity of "FM Stereocasting" and the UHF boom, it was realized that a great need for this type of instrument existed. Sencore engineers did considerable research to develop a Field Strength Meter which is rugged, lightweight, portable and accurate and yet has that "Professional" appearance. Listed below are some of the Special Features of the Sencore FS134 Field Strength Meter. 1. Completely solid state construction provides the utmost in portability, lightweight compactness and battery power economy. 2. Printed circuit construction on unbreakable board material gives dependability and long life. 3. Completely battery operated for field use. Uses standard "C" cells available anywhere. Provisions have been made for installation of a battery charger accessory. 4. Choice of 75 ohm or 300 ohm input from the front panel. 5. Uses most popular type 75 ohm input jack for direct connection to antenna distribution systems, thereby eliminating messy adapters, which can introduce additional SWR losses. 6. Has built-in matching transformer for 300 ohm input. 300 ohm input terminals are of the thumb nut type for complete versatility of any twin lead termination. 7. Built-in 20db (X10) and 40db (X100) attenuators provide control of high level input signals, especially those signals encountered in distribution systems. The attenuators can be used with the 75 ohm or 300 ohm input. 8. Separate VHF and UHF tuners are provided for miximum stability and minimum losses. 9. Three stage 42.8 MC high gain IF system controlled by amplified AGC stages gives stability and good control of both weak and strong input signals. 10. Large four inch meter allows operator to read signal strength from several feet away. 11. Extended logarithmic microvolt range from 30 to 30,000 microvolts permits antennas to be installed without constantly changing the sensitivity range of the meter. 12. Built-in, 3 1/2 inch speaker, with six transistor audio system to drive it, is essential when monitoring FM and TV audio signals.
