HFW59D in its PLUS configuration supplements the Buildingbiology equipment for the upper frequency range up to 10 GHz: Especially for the analysis of the two WLAN/WiFi bands, the recently auctioned 5G band and, of course, radar between 8.5 and 9.5 GHz.

Frequency range: 2.4 - 10.0 GHz

Worldwide unmatched sensitivity at 10 GHz combined with the proven analytical capabilities of the Gigahertz professional equipment

  • In addition to the LogPer antenna included in the standard scope of the device, it also includes the 360° omni antenna as a basis for long-term recordings and particularly advantageous for identifying radar loads at unknown transmitter locations.
  • The HV20_2400G10 preamplifier achieves a sensitivity of 0.01 µW/m² display resolution over the TOTAL frequency range up to 10 GHz.
  • Otherwise, the specification is similar to the HFW59D in the basic configuration:
  • FULL 10 GHz, fully compensated. This unique broadband HF meter allows unfalsified measurements of the frequently used radar frequencies between 8.5 and 9.5 GHz (air traffic control, navigation radar, military radar, weather radar, traffic control). Maximum VBW to display shortest radar pulses (< 0.5 µs).
  • Integrated steep high pass filter at 2.4 GHz reliably suppresses the often dominant GSM and DECT frequencies, thus allowing unfalsified measurements of WLAN/WiFi and the upper area relevant 5G frequency range at 3.4 to 3.8 GHz.
  • Includes an especially designed log-per antenna with excellent directional characteristics.
  • Optimized Peak Hold function with particularly fast response speed due to patented circuitry.
  • 1 µW/m² display resolution (for higher sensitivity, e.g. for minimal wireless LAN signals, use the optional preamplifier HV20_2400G10).
  • Calibrated AC measurement output for the demodulated signal, scalable DC output, for instance for the connection to an NFA for long-term recordings.
  • Quantitative differentiation of pulsed <> unpulsed radiation according to the building biology recommendations.
  • The meter is particularly designed for the measurement of peak values of modulated signals ("pulse"-mode).
  • NiMH battery pack, charge control and power supply unit help avoid unnecessary battery wear.

Delivered in a plastic case K2 with shaped foam filler for safe transport of all components.

Technical Data
