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 push buttons for major oscilloscope functions.
• An 8.4-inch (diagonal) color flat panel display with touchscreen for waveform display,
measurement setup, instrument control, and graphical user interface.
• Front panel USB port.
• 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.
• XGA monitor connection.
• Mouse and keyboard connections.
• LAN 10/100 connection.
• Auxiliary Input BNC (not on 2 channel oscilloscopes).
• Output BNC.
• TTL trigger output BNC.
• USB Interface.
The oscilloscope has several assemblies and four attenuators. Use the oscilloscope block diagram
on the previous page for the following discussion.
