Theory of Operation
The Agilent 1670G-Series Logic Analyzer
LAN Interface
The LAN Interface is primarily a single LAN integrated circuit with supporting components.
Isolation circuitry for the LAN port is included on the I/O board.
Keyboard/Mouse Interface
An 82C42PC PS2 controller makes up the PS2 Keyboard/Mouse interface. The PS2 controller
interfaces the logic analyzer backplane with the keyboard and/or mouse devices.
I/O Board
The Input/Output (I/O) Board primarily includes a Centronics port and two mini-DIN (PS2)
ports for the base 1670G-series products. The I/O board also includes isolation circuitry for
the LAN.
Hard Disk Drive Interface
Buffers interface the hard disk drive with the logic analyzer backplane.
Hard Disk Drive
The Hard Disk Drive is an IDE-compatible disk drive. A 40-pin IDE connector allows the disk
drive to interface with the logic analyzer backplane through the hard disk drive interface.
