Signal Flow
The signals to be measured enter at the input terminals and pass first to the attenuator
(ATT) and preamplifier. Adjusted vertical-axis characteristics (voltage and amplitude) in
accordance with the settings for input coupling, probe attenuation, V/div, and offset value
are passed to the A/D converter.
Voltages are converted to digital values by the A/D converter. The digital data is then
processed by the data processing circuit (digital file processing, etc.). Further, averaging
and other types of processing are performed after cropping at the appropriate sampling
rate (as determined by the time axis settings), and the resulting data is written to the
acquisition memory.
The data written in the acquisition memory is then converted to waveform display data by
the processing circuit and transferred to the waveform processing circuit by which the
data are stored in the display memory. Waveforms are displayed on the screen based
on the data stored in the display memory.
