HFR-4, HF Analyser (1 - 10GHz) in Carrying Case
The HFR-4 is an ABSOLUTE NEW DEVELOPMENT with HF measuring technique from 1 MHz to 10 GHZ!
- latest circuit technology
- best quality
- supported by universities
- approved by expert opinions
By means of the HFR-4 it is now possible for the first time to cover the large frequency range of 1 MHz to 10 GHz. This covers also the frequency ranges of the terrestrian TV, the new digital broadcast, wirless phones, WLAN bands 2.4 and 5.8 GHz, Bluetooth and IEEE as well as the coming up WIMAX bands and some RADAR frequencies.
Via the built-in Peak Hold function it is possible to detect also temporary peak values safely. If this function is activated, the always highest value is "frozen" on the display.
In order to cover the large frequency range the HFR-4 is supplied with two LogPer antennas. Besides the previous antenna (900 MHz to 2.6 GHz) another LogPer Antenna from 2.4 GHz to 10 GHz is supplied. The differentiation of the radiation sources via audio analysis (via the built-in speaker) is possible as well as the determination of pulsed and non-pulsed radiation ratio.
The measuring sensitivity has been explicitly improved, once more. It is ca. 6mV/m, respective 0.1 µW/m²! Via pushbuttons you can choose the measuring units (MV/m or µW/m²). As an option, the HFR-4 is also available with a computer port and a printer output, via which the measuring values can be documented on a computer or a printer (long term recordings).
