Discussion Overview

The discussion revolves around the capabilities of the Tektronix CMD-80 Digital Radiocommunication equipment, specifically whether it can function as a spectrum analyzer. Participants explore its specifications and intended use, focusing on its application in measuring digital signals.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the CMD-80's ability to function as a spectrum analyzer, noting a lack of information in available documentation.
  • Another participant suggests that the CMD-80 does not appear to have the necessary display features typical of a spectrum analyzer, indicating it is more suited for checking digital signals, particularly for CDMA mobile phone signals.
  • A later reply provides additional information stating that the CMD-80 is not an RF spectrum analyzer but can measure adjacent channel power and display results in a frequency domain view, which may resemble a spectrum analyzer display.
  • One participant highlights the value of the CMD-80, noting its original high price compared to its current listing.
  • Another participant offers to share the original brochure or user manual for further clarification on the device's capabilities.

Areas of Agreement / Disagreement

Participants express differing views on the CMD-80's functionality as a spectrum analyzer, with some asserting it cannot serve that purpose while others provide clarification on its measurement capabilities. The discussion remains unresolved regarding its classification.

Contextual Notes

Participants reference specific features and measurements without fully clarifying the implications of these capabilities or the definitions of terms used, leaving some assumptions unaddressed.

Hi everyone.

Was wondering if anyone can tell me if this piece of equipment can be used as a spectrum analyzer? I haven't found much in the way of capabilities in a PDF or whatever. Thought maybe you guys would have a better idea.

doesnt look like it ... it doesn't have any of the screens that show a standard spec an display

looks more like a unit for checking digital signals through a link .. in particular as it states - mobile phone CDMA signals

here's a typical spec an display...

At $50'000 new it's still a brilliant buy at $400 with all those options!
 
The guy mailed me back with this:

The Tek CMD-80 is not an RF spectrum analyzer. The adjacent channel power measurement allows the
user to measure the adjacent, first, and second alternate channel power and display the results in a frequency
domain view. The display shown is similar to a spectrum analyzer.

If you would like to read the original brochure or read the user manual, send me your email and I will email them to you.
