GIGAHERTZ SOLUTIONS HFE59B ຊຸດເຄື່ອງວິເຄາະ RF (27 MHz ~ 2.7 GHz)
Item weight: 2.20 kg
Frequency range: 27 MHz to 2.7 GHz (or 3.3 with increased tolerances)
Measurement range: Power flux density: 0.001 - 1,999,000 µW/m² (i.e. 1 nanoW/m² nominal display resolution to 1.999 W/m² when applying the enclosed amplifier and attenuator)
Precision:
Basic accuracy (CW) including linearity tolerance: +/- 3 dB
Zero offset and rollover +/- 5 digits
Sensor:
2 antennas: 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
Quasi-isotropic ultrabroadband antenna ("omni"-characteristic) aligned for vertically polarised fields
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: AC (demodulated signal, calibrated) and scalable 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 longterm measurements)
AC-adaptor for charging and longterm operation included
