The Downstream Spectrum measurement mode (Optional Purchased Required) allows you to view the entire CATV downstream spectrum frequency range (40 MHz to 1 GHz) in 50 Mhz (default) or 10 Mhz (zoom) frequency spans. The frequency span is determined by the selected center frequency. Within each frequency span a wavy measurement line (trace) with 201 frequency points is formed and continuously updated.

Provides a view over six (6) vertical subdivisions that contain a dynamic range of 60 dB and the ability to view the entire CATV downstream spectrum frequency range in 10 or 50 Mhz frequency spans. The Downstream Spectrum measurement mode allows for a very comprehensive troubleshooting utility that reveals ingress spikes on the forward path as brief as 1 ms.
