Virtual Instrumentation Specification and Selection Guide
V
The ADC-216 is a high resolution, high precision oscilloscope.
The unit is accurate to 1% and has 16 bit resolution. This makes
it ideal for measuring vibrations, noise and audio signals.
The ADC-216 has a large 32k waveform buffer, therefore it is
possible to capture the most complicated signals, then expand
the areas of interest to show finer detail.

In digital electronics a signal change of 1% is usually no problem,
but in audio electronics 0.1% distortion or noise can be a disaster.
Conventional DSO’s only offer 8 bit resolution, so can detect at
best a 0.4% signal change. This means that they are unsuitable
for many applications ranging from monitoring sensors and
transducers to detecting noise and vibration. Precision
oscilloscopes require more than 8 bit resolution.
As well as resolution, noise is an issue. The amplifiers that make
up the ‘front end’ of a conventional DSO are designed to have a
high bandwidth. Low noise is not a priority and so 1% noise
figures are typical. The designer of a 16 bit oscilloscope has a
tough job, noise must be kept below 0.0015% (15ppm), otherwise
the extra resolution will be swallowed up by noise. For more
information, please visit:
