This doesn't pose a problem for AM signals, but is a challenge for SSB and other signals without a carrier.
For this reason, we have developed special test signals which allow for some traditional SSB tests, like two-tone IMD and frequency response, to be performed, although the tests cannot be directly compared to measurements from a true spectrum analyzer.
Exclusive value-added data, above and beyond base navigation charts, make C-MAP by Jeppesen information solutions indispensable. C-MAP NT electronic charts offer the same detail and features customers expect from Jeppesen Marine.
The NT library is updated and maintained for customers who own older chart plotters.
LP-500 is a digital station monitor which displays detailed information about the transmitted signal of a station.
It displays the sampled signals in various formats including Power/SWR, various oscilloscope type displays and a spectrum display.
I was browsing e Bay one day and I ran across a posting for the Analog Devices AD9850.
Its membership of leading engineers, scientists and other authorities has increased dramatically throughout the world, greatly boosting the society's stature and that of its members in a truly symbiotic relationship.In 2005, C-MAP by Jeppesen produced a new NT library with even larger coverage areas than the earlier versions of NT .Bring your electronic charts to life with C-MAP MAX, the ultimate navigator.See Nav Aids on your screen exactly as they appear through your pilothouse window.Get "at-a-glimpse" information about your current strength and direction.
