The RF-toolbox XL is an antenna splitter with a number of indispensable extras when it comes to stable and interference-free reception of the signals from wireless microphones.

The inputs and outputs offer advanced options for fine tuning the antenna signals. The RF toolbox XL is an addition to existing wireless receiver systems and is used as a high-quality main antenna distribution center for receivers of all brands.

Amplify, attenuate, filter

The RF toolbox XL has two inputs and two times eight outputs with N-connectors. In that sense, it acts as a regular antenna splitter. However, the input card has functions which can optimize the signal. Essential in that process are the gain control, the auto gain option and the digitally adjustable bandpass filter. This allows the radio signal from the antennas to be attenuated or increased as filtered. Attenuate to prevent intermodulation and to lower the noise floor. Strengthen to bridge greater distances and obstacles. More selective to prevent intermodulation and to suppress signals from other sources. Known interference signals for wireless microphone systems are WiFi and 4G networks in the immediate vicinity and the digital video signal DVB-T that is distributed over the air.

Output cards

The RF-toolbox XL is supplied with 2×4 or 2×8 output cards. The gain and bandpass filter with a bandwidth of 32MHz can be set for each output of the RF toolbox XL. This frequency range can be set by the user. Each receiver therefore gets exactly the right signal at a strength that eliminates noise and intermodulation distortion. This makes the RF toolbox XL the ultimate nerve center for a set-up under demanding conditions with a larger number of receivers.

Communication

The RF-toolbox XL provides communication with the RF-toolbox booster or LPDA antenna and also power. The RF toolbox booster is an antenna amplifier that can control the level of individual antennas within a system and, for example, can compensate for the cable lengths for each antenna separately. With the RF-toolbox XL, the level of the radio signals can be closely monitored and can be optimally adjusted remotely via the RF toolbox booster. An RF toolbox XL can communicate with a maximum of 32 RF toolbox boosters or LPDA antennes.

Software:

The RF toolbox XL and connected RF toolbox booster can be controlled by PC via USB with the free RF toolbox software.

The OLED window provides the following information and settings:

  • Booster power supply (antenna input): + 13V max. 1,200mA power supply for the RF toolbox Preamp (LED indication for available voltage). Real-time indication of power consumption per input. Automatic reset (max. 10x) when the current is too high. After troubleshooting and recovery, a manual reset can be made.
  • RF input: Both inputs are equipped with a bandpass filter with a bandwidth of 470 to 694MHz. Digitally and independently operable attenuators from 0 to -31.5dB (in steps of 0.5dB). Signal measurement between -70 and + 10dBm, adjustable threshold for the automatic attenuators for reducing intermodulation products.
  • RF output: Depending on the chosen model, 2×4 or 2×8 outputs are equipped with a digitally adjustable bandpass filter with 32MHz bandwidth (other bandwidths on request) and a digitally adjustable attenuator from 0 – 31.5dB (in steps of 0.5dB) . Selectable link for control of A and B output.
  • Remote control RF-toolbox booster or antenna: Bidirectional data communication by the coaxial cable between RF-toolbox XL or RF-toolbox Splitter-8 and RF-toolbox booster or antenna, for setting the gain and status (on / off). Up to 32 RF toolbox Preams can be individually controlled with the RF-toolbox Splitter-8 or RF-toolbox XL. Automatic check for connected Preamps.
  • Software: The RF toolbox XL and connected RF toolbox Preamps can be operated with the free RF toolbox software
