Service Guide 5
Using this book with the 6000L Series oscilloscopes
The 6000L Series oscilloscopes do not have a built-in display or front panel
control keys. If you are using a 6000L Series oscilloscope, and this book refers to
using front panel controls, you can use the built-in Web control feature described
in the 6000 Series Oscilloscopes User’s Guide to complete the instructions. If you
do not have the 6000 Series Oscilloscopes User’s Guide, you may obtain a
printable electronic copy at www.agilent.com/find/mso6000.
Digital Channels
Because all of the oscilloscopes in the Agilent 6000 Series have analog channels,
the analog channel topics in this book apply to all instruments. Whenever a topic
discusses the digital channels, that information applies only to Mixed-Signal
Oscilloscope (MSO) models or DSO models that have been upgraded to an MSO.
Abbreviated instructions for pressing a series of keys
Instructions for pressing a series of keys are written in an abbreviated manner.
Instructions for pressing Key1, then pressing Key2, then pressing Key3 are
abbreviated as follows:
Press Key1 & Key2 & Key3.
The keys may be front panel keys, or softkeys, which are located directly below
the oscilloscope display.
