NASA/TM-108506, Martin, J.L., Interpolation Errors in Spectrum Analyzers, Systems Analysis and Integration Laboratory, Science and Engineering Directorate NASA Marshall Space Flight Center, AL 35812, March 1996, pp. 17, Format(s): PDF 288k |
To obtain the proper measurement amplitude with a spectrum analyzer, the correct frequency-dependent transducer factor must be added to the voltage measured by the transducer. This report examines how entering transducer factors into a spectrum analyzer can cause significant errors in field amplitude due to the misunderstanding of the analyzer's interpolation methods. It also discusses how to reduce these errors to obtain a more accurate field amplitude reading.
