Channel traces are typically 8-bits of vertical data, whereas Math traces
are 16-bits of vertical data. 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.
Accomplishing this - while still providing the ability to view many signals
at one time on the oscilloscope display - 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
www.lecroy.com
for detailed information as to which grid
displays are provided with your oscilloscope.
