3-5 Signal Strength Interference Analyzer (Option 25)
3-4 PN: 10580-00349 Rev. H Spectrum Analyzer MG
3-5 Signal Strength
The Signal Strength meter is useful for tracking down the source of an interfering signal.
This measurement is done at a single frequency in zero span. The power at a frequency
(in dBm and Watts) is displayed along with an optional audible indicator. Connect a
directional antenna and the frequency of the audible indicator increases as the measured
signal strength increases. This mode is especially useful when attempting to locate an emitter
using a directional antenna.
For field strength measurements, antenna factors are included. Antenna factors for many
antennas offered by Anritsu are stored in the instrument. Custom antenna factors can be
created and uploaded into the instrument using Anritsu Master Software Tools software.
