1 Performance requirement not checked in manual.
2Usefui storage performance is limited to the frequency where there are 10 samples per sine wave signal period at the maximum
sampling rate. (Maximum sampling rate is 100 MHz.) This yields a maximum amplitude uncertainty of 5%. Accuracy at the useful
storage bandwidth limit is measured with respect to a six-division, 50 kHz reference sine wave.
