The oscilloscope (1) has an analog/digital transducer (3), which scans a similar signal with a given scanning rate through a frequency converter (8). The input measuring signal (MS) is converted into an analog signal (KS) by decrease in the frequency. The converter has a mixer (9) and a local oscillator (10) and the frequency of the local oscillator is alterable. The converter is arranged partly in a probe (21) of the oscilloscope. |
