HP Logic Analyzer Modules
Termination Adapter
The logic analyzer cable must have the proper
RC network at its input in order to acquire data
correctly. The optional Termination Adapter
incorporates the RC network into a convenient
package. It also reduces the number of pins
required for the header on the target board
from 40 pins to 20.
