Miniport Receiver EB200

Miniport Receiver EB200 is a miniaturized portable professional receiver for the HF-VHF-UHF range. The EB200 is characterized by high input sensitivity and frequency setting accuracy throughout the frequency range from 10 kHz to 3 GHz. Its small dimensions – ˝19“ in size it corresponds to two height units – and low weight as well as a sturdy, pickup-proof die-cast aluminium housing with well-protected integrated operating elements make the EB200 ideal for use in places which cannot be reached with a vehicle. Its low power consumption permits battery operation typically of four hours. The EB200 battery pack is easily accessible and can be exchanged quickly. In case of power supply interruption, all the data is stored. Operation can thus be resumed immediately after the power supply is restored.

EB200 fulfils the following tasks:

• Monitoring of given frequencies, eg storage of 1 to 1000 frequencies, squelch setting, constant monitoring of one frequency or cyclical scanning of several frequencies.
• Searching in a frequency range with freely selectable start and stop frequency and step widths of 1 kHz to 9.999 MHz.
• Location of close-range to medium-range targets with the aid of Hand-held Directional Antenna HE200.
• Detection of undesired emissions including pulsed emissions.
• Detection of unlicensed transmitters communicating illegally or interfering with licensed transmission.
• Protection against tapping by detecting miniature spy transmitters (bugs)
• Monitoring of one's own radio exercises in a service band
• Monitoring of selected transmissions
• Remote-controlled operation via modem and PC in coverage measurement and monitoring systems

Main features

• Ergonomic design for on-body operation
• Continuous frequency range 10 kHz to 3 GHz
• Digital IF section with 12 band-widths (150 Hz to 150 kHz)
• Fast, accurate level indication across 110 dB dynamic range
• Scanning modes – Frequency scanning – Memory scanning – Frequency spectrum
• Remote-controllable via RS232 PPP or LAN (Ethernet 10 Base-T, option)

Active Directional Antenna HE200

Due to its small size and low weight, the Active Directional Antenna HE200 in conjunction with a compact, portable mini-receiver (e.g. EB200) is ideal for tracing signal sources and interfering sources. The direction is found by pointing the antenna towards the direction of maximum signal voltage. The overall frequency range from 20 to 3000 MHz is covered by three exchangeable antenna modules, which handle both vertically and horizontally polarized signals and have almost identical cardioid radiation patterns in both planes

Main features

• Distinct, unambiguous directional pattern

• Wide frequency range

• For vertical and horizontal polarization

• Handy size, low weight

• Wide dynamic range

20 to 200 MHz	200 to 500 MHz	500 to 3000 MHz
