Οδηγίες χρήσης
Frequency range: | A frequency range of down to 27 MHz within the basic device - suitable for the connection of an optionally available antenna (the scope of delivery includes a compensated antenna for 700 MHz up to 2.7 or 3.3 GHz) |
Measurement range: | Power flux density: 0.01 - 19,990 µW/m² |
Precision: | Basic accuracy (CW) including linearity tolerance: +/- 3 dB Zero offset and rollover +/- 5 digits |
Sensor: | Optimised logarithmic periodic antenna with frequency compensation directly on the antenna. Less ripple, better directionality, improved shielding vs. ground, continuous LED-monitoring of quality of connections |
Audio analysis: | Identification of pulsed radiation sources (mobile radio (GSM, UMTS/G3), cordless telephones (DECT), WLAN (Bluetooth), air-traffic control radar) by means of an acoustic signal proportional to the modulation frequency. |
Signal rating: | Display of peak value, peak hold as well as average value (switchable) Quantitative differentiation between pulsed and un-pulsed radiation (patented control) |
Signal output ports: | A calibrated extra AC-measurement output for the demodulated signal, and a DC-output |
Power supply: | Rechargeable high-power 9.6 Volt NiMH battery pack inside the meter, average operation time: 7 - 8 hours Low-Batt. indication Auto-power-off (can be deactivated for long-term measurements) AC-adaptor for charging and long-term-operation included |
