Spectrum analysers are one of the most important test instruments for the RF designer. Rather than displaying amplitude against time as with the case of the oscilloscope, these test instruments display amplitude against frequency giving a plot of the signals. Looking at the control panel of a spectrum analyzer, there are very many different controls to use and this may appear daunting to some. Analogue spectrum analyzers often had controls that needed to be used in conjunction with each other.

A Spectrum Analyzer for the Radio Amateur. Refer to the text for adjustment details. Equivalent parts can be substituted. Maintain reasonableshielding for this part of the system. Additionalattenuator pads can be inserted in linewith one filter or the o the r to approximatelyequalize filter loss in the two paths. You may want to build crystal filters for your analyzer. For a simplifiedbeginning, a very practical analyzercan be built with only one resolution bandwidthof kHz.
White, pink noise. Zelscope Zelscope is a Windows software that converts your PC into a dual-trace storage oscilloscope and spectrum analyzer. It uses your computer's sound card as analog-to-digital converter, presenting a real-time waveform or spectrum of the signal - which can be music, speech, or output from an electronic circuit.

Ham software review. After have reviewed more than fifty HF propagation prediction programs and associated tools, and close to seventy astronomy and imaging -oriented programs, we are going to review applications dedicated to radio amateur activities. They include spectrum analyzers, satellite tracking programs, Morse code trainers, DX atlases, CAT, multi-mode decoders, and other logging programs.
