Frequency Filter Selection

Post by tvl »

Hi,
I am using 4 super beacons and 2 mobile ones, when the mobiles are set on TX.
Browsing through the configuration screens, I saw that most, if not all the beacons, both passive and active, are set on the "31 KHz" filter, despite the fact that only one of them actually transmits in this frequency.
What are the implications of this parameter? should I set it to something different, or the system automatically selects it?

Hello,

Filter setting is not used for tracking in latest version of software (6.240), this setting is now only used for view signal in oscilloscope.
Now system automatically selects the filter according to ultrasonic frequency of the emitting beacon.

Note that if you use NIA and have beacons with different ultrasonic frequencies, you can increase update rate by purchasing MF NIA license:

In regular NIA only one mobile beacon emits ultrasound and updates its location at a time.
But in MF NIA up to 5 mobile beacons with different frequencies can emit ultrasound and update their positions at a time.
Note that modem HW4.9 don't support this feature, modem HW5.1 is needed.
