24 Bit (Handler) I/O Port Overview
The E4990A 24 Bit (handler) I/O port provides four independent parallel
ports for data I/O associated with several control signal lines and the
power line. All signals operate in TTL logic.
The data I/O ports are configured with 2 pairs of 8 bit output port and 2
pairs of 4 bit bi-directional port. Also those ports can cooperate to provide
a maximum 16-bit-width output port or a maximum 8-bit-width input port.
