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.
