Measured with a five-division reference signal, from a 50 Q source
driving a 50 n coaxial cable terminated in 50 0 at the input con
nector with the VOLTS/DIV Variable control in the CAL detent.

Measured with a vertically centered six-division reference signal,
from a 50 Q source driving a 50 0 coaxial cable terminated in 50 0
at the input connector; with the VOLTS/DIV Variable control in
the CAL detent.

Useful storage performance is limited to the frequency where
there are 10 samples par sine wave signal period at the maximum
sampling rate. (Maximum sampling rate is 20 MHz in Single trace
and 10 MHz in CHOP or ALT at a SEC/DIV setting of 5 jis/div.)
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.
