8.2.2.2 Detailed Design Procedure
Use the following primary steps to design a 12-bit oscilloscope:
- Select the desired sampling rate based on the maximum sampling-rate requirement.
- Select the input path components (LNA, amplifier, and other components) based on the maximum input frequency and 1-dB flat-frequency range requirements.
- Set the attenuation range steps based on the required minimum and maximum values for the signal amplitude.
- Select the memory size based on the resolution of the ADC output (12 bits) and the required maximum number of sample points.
