Abstract: PCT No. PCT/DE90/00391 Sec. 371 Date Jan. 29, 1991 Sec. 102(e) Date Jan. 29, 1991 PCT Filed May 28, 1990 PCT Pub. No. WO90/15340 PCT Pub. Date Dec. 13, 1990.In electron beam measuring, it is often also necessary to measure the frequency range in addition to the measuring time range. In order to do this, according to the invented process, the output signal of the local oscillator of a spectrum analyzer, as is known from conventional high-frequency measuring, undergoes a first frequency conversion and subsequently is utilized for modulating the primary beam. Based on the potential contrast as a multiplicative interaction and the modulated primary beam, the under circumstances very high-frequency signal to be analyzed is transformed to an easily detected low intermediate frequency. Subsequently this intermediate frequency signal is transferred into an input frequency plane of the spectrum analyzer by a second frequency conversion. Both the variable input selection frequency or the fixed intermediate frequency of the spectrum analyzer may be the frequency . The measured result appears in the usual manner on the display of the spectrum analyzer.
