New Surecom SF-103 2MHz-2800MHz Digital Frequency Meter Wide Frequency Range SF103 Frequency Counter
Description
SURECOM SF-103 hand held frequency counter is a more practical counter, even advanced functions such as field strength measurement are included. A compact, truly pocket-sized test tool designed for ease of use and reliable performance. Supplied complete with internal lithium-ion battery, AC wall charger and antenna.
Introduction:
Frequency meter Able to measure the frequency parameters of the continuous carrier signal of a walkie-talkie, with a signal strength indicator.
It is a personnel maintenance tool, testing frequency and signal strength for wireless enthusiasts.
This portable frequency counter is designed to count the continuous wave signal coming from a two-way radio.
There are simple ranges for you to choose from. The ranges cover most of the frequency of the two-way radios you want to measure.
Its four-button control is easy to use and its small size allows it to be carried anywhere.
Working with TCXO (temperature compensation X'tal (crystal) oscillator, in the range of -45 ℃ ~ 65 ℃, can reach ± 2 ~ ± 4ppm accuracy
This includes very interesting Frequency Zones such as 2m radio, all VHF and UHF
DMR radio signal e frequency counter.
