These digitizing error sources should be considered in
any measurement.
With static DC input levels, the analog-to-digital converter
may exhibit an ideal transfer function as shown in 12a.
With a dynamic input, however, errors shown in 12b
may appear.
Analog-to-digital converters that exhibit non-linearity
errors cause spurious responses that averaging will
not remove. The 3458A is linear to 16 bits at 100,000
readings/s. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 498
Amplitude roll-off of the 3458A multimeter for its two
different measurement paths.
The effects of timebase jitter is shown here. For the
3458A multimeter, the jitter is 50 ps RMS. This jitter
is repeatable so it can be characterized and
corrected. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 500
