Theory of Operation
This Service Guide supports troubleshooting the Agilent Technologies oscilloscopes to
assembly level. Theory of operation is included only as supplemental information. It is
not comprehensive enough for component-level troubleshooting.
Block-Level Theory
The front panel provides:
• Dedicated knobs and pushbuttons for major oscilloscope functions.
• An 8.4-inch (diagonal) color flat panel display for waveform, measurement, and graphical
interface display.
• A 3 1/2-inch flexible disk drive.
• BNC connectors for channel input signals.
• AutoProbe interface for probe power and probe control.
• A connection for probe compensation.
The rear panel provides several connections:
• The line power input.
• An GPIB connector, for connection to an oscilloscope controller.
• An RS-232 connection.
• A parallel printer connection.
•VGA monitor connection.
• Mouse and keyboard connections.
• LAN 10/100 connection.
