Fixed Frequency" Mode - Secotech ST-031M Piranha User Manual

The first time you open the program, it activates the list, established by the manufacturer (430-450 MHz - without
the "handler"). To create a new list, it is needed to activate with the button "Edit". The user can edit, add or
delete the row from the list. Form of entered data consists of two border limits Fmin - Fmax (width not more than
100 MHz), and the so-called "Handler" (Figure 43). Under the handler is placed a special pattern, characterising a
certain type of digital communication. If the "handler" is set, then only the signals, corresponding to that pattern
of that frequency range will be detected. If the handler is not set, the device will display all signals in the set
range. After the activation with the button "Save", the user list is placed into the memory of main unit of ST-031M
and can be used without the PC.
