Wide Range Signal frequency Counter SF-103 SURECOM For DMR Analog Two Way Radio Walkie Talkie CTCSS CDCSS TCXO Meter Measurement

Introduction:

Portable Frequency Counter SURECOM SF103 Support test frequency from 2MHz-200MHz / 27MHz -2800MHz ,capable of measuring the parameters of the frequency of the continuous carrier signal walkie-talkies , with signal strength indicator.CTCSS/DCS testable for 144/430MHz,DMR Digital Signal Testable

◊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&39;tal (crystal) Oscillator) ,In the range of -45°c ~ 65°c can reach ± 2 ~ ± 4ppm accuracy

◊This include very interesting frequency areas such as 2m HAM radio, all VHF and UHF

◊DMR Radio signal  frequency counter.

1.6 How to check Frequency of Digital DMR Radio
      Press[ F2 ] botton ,[F3 --->] select Function to" type" :Press [F4] select Analog / Digital(DMR) ,
      and then Press [F2] to Run
      Note. Digital mode have 3 Decimal only.

1.7 How to ADJ. the Frequency mode of 27MHz -2.8GHz: ( See PIC.2)
       Press, [F3 MENU ] , [F3 Down] / [ F4 Up] to select the Gate to (0.1s/0.25s/0.5s/1.0s)
       Press, [F2 Edit] / [F3 - ] and [ F4 +] to select the +/- 99
       Press, [F1. Main] exit , and then press [F4 save] for save the setting .([F1] not save for exit)

1.8 How to fine tune the Frequency mode of 2-200MHz: (See PIC.1 )
      Tune the PCB VR1 (Variable resistance)
      (The factory has been set accurate, such as non-technical staff do not tune)

1.9 How to use  [F3 menu ] mode: (see PIC2)
      Press, [F3 - ] / [ F4 +] select the function ,and then press [F2 edit] for edit mode  , 
      Press, [F3 - ] / [ F4 +] selecy for change the data .
      Press, [F1. Main] exit , and then press [F4 save] for save the setting .([F1] not save for exit)

Caution:
      1)Max. direct input signal 5Vp-p
      2)Prohibit direct access to the radio antenna output, resulting in damage to the frequency meter
