Display
Oscilloscope display grids present the trace information in a voltage vs.
time format. The oscilloscope analog-to-digital converter (ADC) information
is displayed vertically on the grid with the ADC bits divided proportionally
according to their amplitude on the grid. Channel traces are typically 8-bits
of vertical data, whereas Math traces are 16-bits of vertical data. Teledyne
LeCroy grids consist of eight vertical divisions.
When displaying channel traces on the grid, use of less than full-grid
amplitude results in some reduced vertical resolution and accuracy. For
instance, if a channel trace is displayed as two divisions high on a grid, the
number of ADC bits utilized is...
2/8 * 2^8 or 64 bits
This is quite less than the full 8-bit resolution. Such a reduction in vertical
resolution may be acceptable if the primary measurement consideration is
for rough timing measurements; however, if vertical accuracy or extreme
timing accuracy is a requirement, it is better to increase the amplitude of
the signal to utilize close to maximum grid height. In order to accomplish
this while still providing the ability to view many signals at one time on the
oscilloscope display Teledyne LeCroy provides multi-grid capability. This
creates multiple oscilloscope grids, each with 8-bit vertical resolution, and
allows many full-resolution grids (but vertically smaller in grid height) for
concurrent display without affecting the vertical resolution.
Different grid displays are available based on instrument and installed software
packages. For example, some displays show side-by-side, instead of vertically
stacked grids. The additional grid displays offer more convenient views of multiple
waveforms. Refer to your instrument datasheet at
for detailed
information as to which grid displays are provided with your oscilloscope.
