Test Equipment

The AD56645 14 Bit A/D converter takes 105 mega samples a second, which implies a Nyquist limit of 52.5 MHz.
In actual sampling operation the 2 LSBs are ignored. The output of the A/D converter is can be saved to a comma delineated Excel file 16,384 samples at a time, stored in 16 bit range.

The oscilloscope is a Tektronix 2230 100 MHz job with a nifty digital storage feature that will take 1K or 4K of samples (from Ebay). Its sampling rate is 20 mega samples a second.

Since the scopes visual mode is faster than the software ADC version, and the ADCs sampling rate is faster than the scopes sampling rate, the pair of them are useful in conjunction.
