Alaris DF-A0047 Handheld Direction Finding Antenna (Offered by Tektronix)
Tektronix offers the Alaris DF-A0047 direction finding antenna for use in interference hunting applications with our USB spectrum analyzers and SignalVu-PC Map application software. The DF-A0047 contains multiple antennas and a user-selectable preamplifier to cover a broad range of interference frequencies and levels. Powered via USB, the DF-A0047 includes an integrated compass that transmits angle information to the SignalVu PC Map application for automatic creation of lines of bearing on the map.
