N2  - A time-expansion sweep frequency spectrum analyser is described for signals in the 0-3 MHz frequency range. It is based on a standard video tape recorder used in the single frame replay mode. With a time-expansion ratio of 400 between the record time and replay time, a frequency resolution of 10 kHz together with a time resolution of 0·5 ms is realized. An example of the spectra of Jupiter radio bursts made with the analyser is presented.
