Connect the measurement chain

Connect the near-field probe to the amplifier input with a 50 ohm coaxial cable rated for the band of interest. Connect the output to the instrument and power the amplifier with the supplied adapter. Account for amplifier gain and cable loss when interpreting absolute signal levels. Check both amplifier compression and the instrument input limit when strong signals are present.
