Title: Sampling signal generating circuit
Inventor: UKITA JUNICHI
IPC: G01R13/20
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To conduct sampling with a high precision and with a stable high time-resolution without being influenced by the variation of a trigger signal, by generating a sampling signal of a frequency different slightly from the trigger signal, based on an independent reference signal being different from the trigger signal. SOLUTION: A first frequency mixer 11 mixes the frequencies of a trigger signal Ft and a first reference signal F1 asynchronous with this ahd having an arbitrary frequency, and a signal Ft +F1 is outputted through a first filer(HFP) 21. Next, a second frequency mixer 12 mixes the frequencies of this signal Ft +F1 . and a second frequency signal F2 (F1 +Δdf) synchronous with the first reference signal F1 and having a frequency different from the first reference signal F1 by a slight predetermined frequency Δf, causes it to pass a second filter(LPF) 22, and outputs a sampling signal Fs of a frequency Ft -Δf. Consequently, it becomes possible to perform sampling, maintaining synchronism between the trigger signal Ft and the sampling signal Fs , without being influenced by the frequency variation of the trigger signal Ft .
