Der Empfänger EM 1031-U enthält zwei getrennte Eingangsteile für die Antennen A und B. Auf das jeweils stärker empfangene Signal wird automatisch umgeschaltet und dieses zur Aufbereitung weitergeleitet.

Das Funktionsprinzip wird als "Diversity-Betrieb" bezeichnet. Es hilft, "Feldstärkelöcher" auszugleichen und kann einen Gewinn beim Stör-/ Nutzsignalverhältnis von bis zu 26 dB bringen, die Betriebssicherheit erhöht sich circa um den Faktor 20.

L2 zeigt den empfangenen Diversity-Kanal an.

The EM 1031-U receiver has two separate input sections for antennae A and B and automatically switches to whichever antenna signal is stronger.

This principle is called diversity operation. It helps to compensate for "field strength gaps" and increases the signal-to-noise ratio by up to 26 dB. Thus, reliability is increased by a factor of about 20.

L2 indicates the active diversity channel.

El receptor EM 1031-U cuenta con dos secciones de salida separadas para las antenas A y B; conmuta automáticamente a la señal de antena más fuerte.

Este principio de funcionamiento se denomina „Diversity“. Ayuda a compensar los „vacíos de intensidad del campo“ y con ello puede obtenerse una ganancia de hasta 26 dB en la relación señal parasitaria/útil. Además, la seguridad de funcionamiento es 20 veces mayor, aproximadamente.

L2 indica el canal „Diversity“ activado.
