Den drives av et oppladbart litiumbatteri eller (2) AA.MPR52-ENG har multiband-frontend-filtrering:470-960 MHz Moving Filter960-1160 MHz (DME) Moving FilterLandsspesifikke sagfiltre: USA 935-960 MHz og Japan 1240-1260 MHzVia programvaren kan mottakeren settes til å fungere i enten Smal- eller brebånd-modus. Smalbåndtillater 50% mer bånd effektivitet ogca 3dB ekstra følsomhet og støy avvisning.Den spenningsstyrte oscillatorentillater 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.Frequency Ranges470 ÷ 800 MHz, 960 ÷ 1160 MHz (DME) and 940 ÷ 960 MHzSwitchable Channels2400 managed in 40 groups ofr 60 frequencies completely user customizableSwitching-WindowUp 790 MHzFrequenciesmicroprocessor controlled frequency synthesizer circuit, with 5 kHz minimum step; frequencies is easily PC reprogrammed with USBmini interface or optional UPKmini programmerFrequency ErrorLess than ± 2.5 ppm, within the rated temperature rangeModulationFM mono, wideband or narrowband IFB (SW selectable)Peak Deviation±54 kHz (wideband), ± 40 kHz (narrowband)Antenna Input Impedance50 ohm sma type (SWR < 1:2; typ. 1:1.4)Sensitivity2 µV ( 6 dBµV), for SND/N > 58 dB; 5 µV (14 dBµV), for SND/N > 98 dB in the whole switching-windowAmplitude ResponseLess than 0.5 dB (for RF input signal:6 dBµV ÷ 100 dBµV)Co-Channel RejectionGreater than 80 dB typical (for channel spacing = 400 kHz)Spurious EmissionsLess than 2 nW (typical = 0.1 pW)Noise Reduction SystemENR / ENR-1.2 (Wisycom Extended-NR) , noise optimized; ENC / ENC-1.2 (Wisycom Extended-NC), voice optimized & with reduced pre-emphasis; Others, compatible with most systems, thru an internal DSP emulation of SA572, SA575 and Rms envelope compander chip set, fully user programmableAF Bandwidth30 Hz ÷ 20 kHz (wideband), 30 Hz ÷ 15 kHz (narrowband)Frequency Response± 0.5 dB in the 30 Hz ÷ 19 kHz range (wideband), ± 0.5 dB in the 30 Hz ÷ 13 kHz (narrowband)Distortion0.3 % typicalSND/D Ratio (analog)100 dB typicalSND/D Ratio (AES3)Less than 125 dB typicalAudio OutputElectronically balanced on 5 pin mini-XLR Female connector Analog or digital (SW selectable), impedance = 200 ohmAudio Output LevelMAX +18 dBu (peak deviation), adjustable in one dB step in a range of 54 dBDigital OutputAES3 @ 48 kHzMonitor OutputStereo Plug 3.5mm(TRS) Locking (M6 x 0.5 thread)Monitor Output Level2 X 100mW @ 32 OhmManaging Interfacemini USBPower Leds3 colors dedicate LEDDisplayOLED 128×64 (white)Powering2 x IEC-LR6 1.5V size-AA alkaline or NiMh rechargeable ; C3-V3 battery pack ; KLIC 8000 or CR-V3R lithium (i.e. DR9708 duracell)Battery Lifeapprox. 7 hours with MPRLBP Lithium-ion battery pack CS-KLIC8000 type ; approx. 3.5 hours with 2x AA Alkaline batteries Energizer ; approx. 4.5 hours with 2x AA NiMH 2.5AhTemperature Range-10 ÷ + 50 °CDimensions91mm x 71.5mm x 27mm (HxWxD) with clipWeight100 g approx. without batteries
