SURECOM SF-103 Portable Frequency Counter 2MHz-2.8GHz

SURECOM SF-103 Portable Frequency Counter 2MHz-2.8GHz

SF103RF frequency counter

New Function: for analog and digital Radio 

 

Introduction:

  • The frequency meter capable of measuring the parameters of the frequency of the continuous carrier signal walkie-talkies , with signal strength indicator.
    it is the tool of choice for maintenance personnel ,test frequency and signal strength of wireless enthusiasts.
  • This portable frequency counter is designed for counting continuous wave signal comes from Two-way Radio. 
  • There are easy ranges for you to choose. 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 you to carry it anywhere you like.
  •  Work by  TCXO(Temperature Compensate X'tal (crystal) Oscillator) ,In the range of -45 ℃ ~ 65 ℃ can reach ± 2 ~ ± 4ppm accuracy
  • This include very interesting frequency areas such as 2m HAM radio, all VHF and UHF
  • DMR Radio signal e frequency counter.
  • Easy Battery level

Power On –Press and Hold down the [black key] by 2 second 
Power Off –Press and Hold down the [black key] by 4 second of number count down to 0
Charging the battery 
Plug the Power cord into adaptor , Micro USB connected SF-401, The Led indicating:
 *The RED Led is light - Charging        
 * The Green Led is light - Full 
How to check Frequency measuring.    See PIC.3

The transmitter near the frequency counter antenna , see the signal reception conditions is zone green, you can test. Please see Pic.3
cautions: 
e.g. display 1800.000Mhz  , The transmitter distance is too close to the frequency counter will affect the test results, , the signal bar is red .(see Pic.1)
e.g. display 0.000, , The transmitter distance is too far to the frequency counter and signal is weak ,will affect the test results,  the signal bar is low .(see Pic.1)

How to check Frequency of Digital DMR Radio 
Press[ F3 Digital] from Measuring screen mode   See PIC.1
Note: Use Digital mode have 3 Decimal only

MENU funtion setting and save.    See PIC.4
