Using this Manual
This manual will show you how to use the HP 64700-Series
analyzer with the host computer SoftkeyInterface.
This manual will:
Brieflyintroduce the analyzer and its features.
Showyou howto use the analyzer in itssimplest, power-up
condition. From there, it will progressively show you how
and whyyou would use additional trace commands.
Showyou howto use the trace displayoptions.
Showyou howto connect the external analyzer probe to
target system signalsand howto configure and use the
external analyzer.
Showyou howto set up the analyzer trigger to break the
emulator into the monitor program.
Showyou howto drive externalCoordinated
Measurement Bus (CMB) or BNC trigger signals with the
analyzer trigger.
Showyou howto use the TimingAnalyzer Softkey
Interface.
This manual will not:
Showyou howto use everySoftkeyInterface command
and option; the SoftkeyInterface is described in the
Softkey Interface Reference.
Showyou howto use coordinate measurements between
multiple emulators; specifics on background,
specificationsand use are described in the "Coordinated

Measurements"chapter of the HP64700-Series Emulators
Softkey Interface Reference.
1Organization
Chapter 1 Introducing the Analyzer. This chapter lists the basic features of
the analyzer. The following chapters showyou howto use these
features.
Chapter 2 Getting Started. This chapter showsyou howto use the analyzer
from its simplest power-up condition to specifyingtrigger
conditions,storage qualifiers, prestore qualifiers, and count
qualifiers.
Chapter 3 Displaying Traces. This chapter describes options available when
displaying the trace.
Chapter 4 Making Software Performance Measurements. This chapter
describes software performance measurements, describes the steps
in making measurements with the Software Performance
Measurement Tool (SPMT), and shows you example
measurements made on the demo program.
Chapter 5 Using the External Analyzer. This chapter shows you howto
connect the external analyzer probe to target system signals and
howto configure and use the external analyzer.
Chapter 6 Timing:Introduction. This chapter introduces the external timing
analyzer and describes its features.
Chapter 7 Timing:Getting Started.Thischapter shows you howto start up
the timing analyzer SoftkeyInterface and howto do a simple
timing measurement.
