Antenna detection Narda Directional Antennas are automatically detected (type,
polarization, consideration of typical antenna factors, preamp gain
and frequency response).
For other antennas parameters can be defined and selected
manually.
Cables and external devices Narda RF cables are automatically detected (type, frequency
response and more)
Other cables and external devices (e.g. filters) can be defined and
selected manually.
