SPECTRAL DETECTIVE
Allows the AXS-200/625 to bridge (high-impedance) onto a live circuit to display a plot of transmitted levels and spectrum (PSD). The Spectral Detective test can be
referenced to any user-selected impedance. The impedance reference setting is required to display proper readings in dBm/Hz or dBm.
