Level Measurement TV Analogue

After you have set a channel or a frequency, the level is automatically measured and displayed on the LC display either in dBµV or in dBmV (depending on the basic configuration). The input level can be measured in the range of 30 dBµV to 120 dBµV (-30 dBmV to 60 dBmV).
