Wisycom MPR52-ENG er en tokanals mangfoldsmottaker som avstemmer fra 470 - 1260 MHz og kan brukes enten for smal eller bredbånd med et valgbart 100/200 KHz filter. Den drives av et oppladbart litiumbatteri eller (2) AA.
MPR52-ENG har multiband-frontend-filtrering:
- 470-960 MHz Moving Filter
- 960-1160 MHz (DME) Moving Filter
- Landsspesifikke sagfiltre: USA 935-960 MHz og Japan 1240-1260 MHz
Via programvaren kan mottakeren settes til å fungere i enten Smal- eller brebånd-modus. Smalbånd tillater 50% mer bånd effektivitet og ca 3dB ekstra følsomhet og støy avvisning.
Den spenningsstyrte oscillatoren tillater en ultra-rask spektrumskann. Mottakeren kan til og med automatisk programmere senderen over infared etter en skanning. MPR52-ENG kan også overvåkes og styres via en USB-tilkobling til en datamaskin som kjører WisyCom Manager 2.0-programvaren, som også kan lese skanningsdata fra mottakeren.
Fleksible batteriløsninger tillater at enheten drives via et oppladbart litiumbatteri eller to AA-batterier. Batteripakken kan lades inne i enheten over USB eller i en dedikert lader.
