Spectral Detective
Allows the CableSHARK 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.
Mode:
Continuous or Peak-hold plot with cursor and zoom
Bridging impedance:
15 k
Ω
Vertical scale:
-10 to –153.3 dBm/Hz or +20 to -120 dBm
Horizontal scale:
2.16 kHz to 2.2 MHz, in 2.16 kHz steps, optional 6 MHz support available
Noise filters:
None or E, F, G (IEEE-743 / 1995)
4-Wire Crosstalk
Single frequency measurement or plot of crosstalk with cursor and zoom. Crosstalk levels below 60 dB may
be affected by internal crosstalk of the unit itself.
