SURECOM Frequency Counter SF401 Plus SURECOM Portable CTCSS/DCS Decoder
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

Power On/Off 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) ! Note: (27MHz to 100MHz It can not be guaranteed and the corresponding normal emission appliance) .
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 Press [F1] > into menu Page Press [F3 down] or [F4 Up] into System and Press [F2 Rtn] into system Page PIC.4 Press[F3 down] or [F4 Up] select funtion ,Press [F2 Edit] > [F3 - ][F4 +] change mode Press[Menu] > [F1 ]to Exit or [F4 ] to Save and Exit
Menu Setting Rf defect level: The smaller the rf detect level, the more sensitive
How to check CTCSS/DCS code 1.Radio must be 136-174/400-520MHz 2.Radio must be ANALOG
