Front-Panel Operation
By now you should be somewhat familiar with the VERTICAL or
ANALOG, STORAGE, HORIZONTAL, TRIGGER, and DIGITAL
groups of front-panel keys and knobs. You should also know how to
determine the setup of the oscilloscope by looking at the status line. If
you are unfamiliar with this information, we recommend that you read
the introductory material at the start of this manual.
HP 54645A and HP 54645D Channels
Because both the HP 54645A Oscilloscope and the HP 54645D
Mixed-Signal Oscilloscope have analog channels, the analog channel
topics in this chapter apply to both instruments. Whenever a topic
discusses the digital channels, that information applies only to the
HP 54645D Mixed-Signal Oscilloscope.
Oscilloscope Channels are Labeled Differently
On the HP 54645A Oscilloscope, the analog channels are labeled 1 and 2 since
there are no digital channels. On the HP 54645D Mixed-Signal Oscilloscope, the
analog channels are labeled A1 and A2 to distinguish them from the digital
channels.
