Field Strength Measurement
Field Strength measures the signals reaching an antenna. The SignalHawk
automatically corrects the sweep data for the antenna’s gain and frequency
dependence and displays it in dBm / m.
1. Connect an antenna to the RF In connector on the SignalHawk.
Note:
Use an antenna with known gain characteristics.
For best accuracy, set the start and stop frequencies to the mea-
surement range of the chosen antenna.
2. Select Antenna and select the antenna type from the drop down list.
Note:
The antenna type, valid frequency range, and gain
in dB (relative to an isotropic radiator) are shown in the
measurement settings area.
3. Measure the strength of the signal emanating from a transmission
antenna (within the frequency range of the antenna connected to
the RF In port).
4. Move to various positions relative to the transmitting source and
observe the signal value.
