Spectrum Analyzer Mode
In the Spectrum Analyzer mode, the instrument displays all or part of the
CATV system spectrum, with variable spans from 3 to 50 MHz. A dynamic
range better than 60 dB over the six vertical subdivisions of the display
graph allows for comprehensive troubleshooting utility. Spectrum
measurement mode reveals ingress spikes as brief as 5 µs.
The Zero-Span mode of the spectrum analyzer displays a single frequency
over time. You can examine individual TDMA (modems, most return path
signals) and continuous carriers (digital video, most forward path signals).
Pressing the Spect measurement mode key activates the spectrum
analyzer, or you can get to the SPECTRUM screen through the Navigator
menu (see Fig. 7-1).
