PNA Series Microwave Network Analyzers Theory of Operation
N5230A Digital Processing and Digital Control Group Operation
Rear Panel Interconnects The rear panel includes the following interfaces:
A40 Floppy Disk Drive
The A40 floppy disk drive allows you to store and recall instrument states and
measurement results on a 3.5 inch, 1.44 MB floppy disk. This assembly is connected
directly to the A14 system motherboard.
A41 Hard Disk Drive
The hard disk drive assembly (HDDA) is an integrated development environment (IDE)
data storage device which is connected directly to the A15 CPU board. The full operating
system and firmware for the network analyzer is stored on the A41 hard disk drive.
USB Hub
The rear-panel mounted, internal USB hub provides four additional USB ports for
connection of external USB compatible devices.
USB A universal serial bus (USB) jack (an industry standard 4-pin connector).
GPIB A 24-pin, female, type D-24 connector that meets IEEE-488 standards.
Serial A 9-pin, male, RS-232 compatible, D-sub connector.
Parallel A 36-pin, mini-D, 1284-C connector that provides connection to printers or
any other parallel port peripheral.
LAN A standard 8-pin, 10/100BaseT, Ethernet connection. It auto selects between
the two data rates.
Display (VGA ) A 15-pin, female, D-sub connector that provides a video output of the
analyzer display that can be viewed on an external VGA monitor.
