Description
The Surecom SF-401 Plus frequency counter is a device used to measure the frequency of radio signals in the radio frequency (RF) range. This type of device is especially useful for radio amateurs, radio technicians, and anyone who needs to measure the frequency of radio signals.
Frequency Range: The SF-401 Plus is capable of measuring frequencies in a range typically ranging from 27 MHz to 3 GHz. This makes it suitable for measuring frequencies in most amateur radio bands and other radio applications.
LCD Display: It features an LCD display that displays the frequency measured in kilohertz (kHz) or megahertz (MHz), depending on the scale and accuracy required.
Power: The device is usually powered by an internal rechargeable battery or can be powered by an external power source.
Additional functions: Often, these types of frequency counters can also have additional functions, such as sensitivity adjustment, detection threshold adjustment, and the ability to count RF pulses or events.
Antenna or Input Connection: To measure an RF signal, an antenna or coaxial cable must be connected to the input of the frequency counter.
Portability: The SF-401 Plus is usually a portable and compact device, making it easy to use in different locations.
Accuracy: The accuracy of these types of frequency counters can vary, so it is important to calibrate them correctly if high accuracy is needed.
Common Use: Amateurs often use these devices to adjust their transmitters and receivers, and they are also useful for troubleshooting radio and communication equipment.
Surecom SF401 Plus 27Mhz-3000Mhz Radio Frequency Counter Portable Meter with CTCCSS DCS Decoder
The frequency meter capable of measuring the frequency parameters of continuous carrier signal walkie-talkies, with signal strength indicator.
This portable frequency counter is designed to count the continuous wave signal coming from bidirectional radio.
There are easy ranges for you to choose from. The ranges cover most of the frequency of the bidirectional radios you want to measure.
Its four-button control is easy to use, and its small size allows you to take it anywhere you want.
Working by TCXO (X’tal (crystal) oscillator of temperature compensation), in the range of -45 C ~ 65 C can reach an accuracy of ± 2 ~ ± 4 ppm.
