Digital Broadcasting Ghost (Reflection Wave) Disturbance Countermeasure Solution

Countermeasures against reception interference caused by ghosts in the medium electric field area!

If you have any questions regarding the introduction below, please feel free to contact us. ◆◇◆Features◆◇◆ It can perform spectrum measurements in a wide bandwidth supporting 50 kHz to 3.3 GHz. Errors due to ghost (reflected wave) interference have been reported in medium field areas around urban centers. Even if the digital broadcast terminal level is between 40 to 50 dB, it may not be received by the tuner, or block noise may occur. In this case, in addition to the general confirmation of BER/MER, it is necessary to implement countermeasures after checking the ripple drop intervals. By setting the span during measurement to 10 MHz and checking the C/N ratio, we can further narrow down the analysis and identify interference points based on the spectrum state during reception. Additionally, by using the full span function, it is possible to display the wideband spectrum from 50 kHz to 3.3 GHz on the same screen. This is the optimal tool for identifying which frequency bands are experiencing multipath or if distortion is occurring due to booster interference.
