20 MHz Pattern Input/Output Module is a C-size,1-slot, register-based VXI module
The HP E1452A Pattern Input/Output Module is a C-size,
1-slot, register-based VXI module that is used to send
data to and receive data from a device under test. This
module is part of the HP 75000 Model D20 but can be
used standalone. Since it does not contain an internal
time base, it is normally clocked over the local bus by the
HP E1450A Timing Module in an HP 75000 Model D20
Digital Functional Test System. However, when used
standalone, the HP E1452A is clocked by an externally
supplied signal.
