2.4.6 Selecting the Pulser Width (OPTIONAL)
The standard pulser shape is a spike, and there is also an optional square pulser shape available. If the PULSER TYPE option is activated
and a SQUARE wave is chosen, the user may specify the time-based width of the pulser. The pulser width generally varies from
30 to 500 nanoseconds. The pulse width value is expressed as half of the bipolar square wave pulse width. A recommended starting point
from which the width setting can be adjusted is found with the following equation:
For example, if a 2 MHz probe is used, the equation becomes:
PULSE WIDTH (nanoseconds)
