SF-401PLUS

New ver 4.0 Frequency Counter SF-401 PLUS SURECOM Portable CTCSS/DCS Decoder 


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 
  • digital mode for DMR radio only, not for other digital device

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)
!  Note: (27MHz to 100MHz It can not be guaranteed and the corresponding normal emission appliance)  .
 

How to check Frequency of Digital DMR Radio
