Die volle Empfindlichkeit wird bei einer Burstlange von mindestens 6 Pulsen erreicht. Die Reichweite bei Verwendung eines typischen Senders (SFH 4510/SFH 4515, IF = 500 mA) betragt etwa 30 m. A minimum burst length of 6 pulses is necessary for full sensitivity. The transmission distance with a typical transmitter (SFH 4510/SFH 4515, IF = 500 mA) is about 30 m.
