Logic Analyzer Overview
Front Panel
HP 1670D-Series Logic Analyzer
Select Key
The Select key action depends on the type of field currently highlighted. If
the field is an option field, the Select key brings up an option menu or, if
there are only two possible values, toggles the value in the field. If the
highlighted field performs a function, the Select key starts the function.
Done Key
The Done key saves assignments and closes pop-up menus. In some fields, its
action is the same as the Select key.
Shift Key
The shift key, which is blue, provides lowercase letters and access to the
functions in blue on some of the keys. You do not need to hold the shift key
down while pressing the other key — just press the shift key first, and then
the function key.
Knob
The knob can be used in some fields to change values. These fields are
indicated by a side view of the knob placed on top of the field when it is
selected. The knob also scrolls the display and moves the cursor within lists.
If you are using a mouse while dragging, you can do the same actions by
holding down the right button.

Logic Analyzer Overview
To make a measurement
To make a measurement
For more detail on any of the following information, see the referenced
chapters. If you are using a preprocessor with the logic analyzer, some of
these steps may not apply.
Map to target
Connect probes Connect probes from the target system to the logic
analyzer to physically map the target system to the channels in the logic
analyzer. Attach probes to a pod in a way that keeps logically-related
channels together. Remember to ground each pod.
See Also "Probing" in Chapter 7 for more detail on constructing probes.
Set type* When the logic analyzer is turned on, Analyzer 1 is named
Machine 1 and is configured as a timing analyzer, and Analyzer 2 is off.
To use state analysis, state compare, or software profiling, you must set
the type of the analyzer in the Analyzer Configuration menu. You can
only use one timing analyzer at a time.
Assign pods* In the Analyzer Configuration menu, assign the
connected pods to the analyzer you want to use. The number of pods on
your logic analyzer depends on the analyzer model. Pods are paired and
are always assigned as a pair to a particular analyzer.
* If you load a configuration file, this step is not necessary.
1-4
Logic Analyzer Overview
To make a meas urement
Set up analyzers*
Set modes and clocks Set the state and timing analyzers using the
Analyzer Format menu. In general, the timing modes trade channel
count for speed. The state analyzer provides for complicated clocking. If
your state clock is set incorrectly, the data gathered by the logic analyzer
might indicate an error where none exists.
See Also "The Format Menu" in Chapter 7 for more information on modes and clocks.
Group bits under labels The Analyzer Format menu indicates active
pod bits. You can create groups of bits across pods or subgroups within
pods, and name the groups or subgroups using labels.
* If you load a configuration file, this step is not necessary.
1-5
Logic Analyzer Overview
To make a measurement
Set up trigger*
Define terms In the Analyzer Trigger menu, define trigger variables
called terms to match specific conditions in your target system. Terms
can match patterns, ranges, or edges acrossds multiple labels.
Configure Arming Control Use Arming Control if
you want to correlate the triggers and data of both analyzers
•
you want to use the logic analyzer to trigger an external instrument, or
•
you want to use an external instrument to trigger the logic analyzer.
•
Set up trigger sequence Create a sequence of steps that control when
the logic analyzer starts and stops storing data, and filters which data it
will store. For common tasks, you can use a trigger macro to simplify the
process, or use the user-defined macros to loop and jump in sequence.
See Also Chapter 4, "Using the Trigger Menu" and Chapter 5, "Triggering Examples"
for more information on setting up a trigger.
"The Trigger Sequence" in Chapter 9 for more information about the trigger
sequence mechanism.
"To save a configuration" and "To load a configuration" in Chapter 6 for
instructions on saving and loading the setup so you don’t have to repeat
setting up the analyzer and trigger.
* If you load a configuration file, this step is not necessary.

Logic Analyzer Overview
To make a meas urement
Run measurement
Select single or repetitive From any Analyzer menu, select the field
labeled Run in the upper right corner to start measuring, or press the
Run key. A single run will run once, until memory is full; a repetitive run
will continue until you select Stop or until a stop measurement condition
that you set in the markers menu is fulfilled.
If nothing happens, see Troubleshooting. When you start a run,
your analyzer menu changes to one of the display menus or a status
message pops up. If nothing happens, press the Stop key. If the analyzer
still does not display any measurements, see Chapter 10,
"Troubleshooting." If memory length is large it will take a noticeable
amount of time to fill, and data is not displayed during acquisition.
Gather data You can gather statistics automatically by going to the
Waveform, Listing, or Chart menu, turning on markers, and setting
patterns for the X and O markers. You can set the analyzer to stop if
certain conditions are exceeded, or just use the markers to count valid
runs.
See Also "Markers" in Chapter 7 for more information on markers and stop
measurement conditions.
1-7
Logic Analyzer Overview
To make a measurement
View data
Search for patterns In the Waveform, Listing, and Chart menus, you
can use symbols and markers to search for patterns in your data. In these
menus, toggle the Markers field to turn the pattern markers on, then
specify the pattern. When switching views, markers keep their settings.
Correlate data You can correlate data by setting Count Time in your
state analyzer’s Trigger menu, and then using interleaving and mixed
display. Interleaving correlates the listings of two state analyzers. Mixed
display correlates a timing analyzer waveform and a state analyzer listing.
You can also correlate data by setting the analyzer type to State
Compare, acquiring the data, then using the Compare menu to do a
bit-by-bit comparison between the acquired state data and a reference
listing.
The System Performance Analysis (SPA) Software does not save a
record of actual activity, so it cannot be correlated with timing or state
mode.
Make measurements The markers can count occurrences of events,
measure durations, and collect statistics. The SPA provides high-level
summaries to help you identify bottlenecks. To use the markers, select
the appropriate marker type in the display menu and specify the data
patterns for the marker. To use SPA, go to the SPA menu, select the
most appropriate mode, fill in the parameters, and press Run.
See Also Chapter 8, "System Performance Analysis (SPA) Software" for more
information on using SPA.

Connecting Peripherals
Connecting Peripherals
Your HP 1670D-series logic analyzer comes with a PS2 mouse. It also
provides connectors for a LAN, keyboard, Centronics (parallel)
printer, HP-IB, and RS-232-C devices. This chapter tells you how to
connect peripheral equipment, such as the mouse or a printer, to the
logic analyzer.
Mouse and Keyboard
You can use either the supplied mouse and optional keyboard, or
another PS2 mouse and keyboard with standard DIN connector. The
DIN connector is the type commonly used by personal computer
accessories.
Printers
The logic analyzer communicates directly with HP PCL printers
supporting the Printer Control Language or with other printers
supporting the Epson standard command set. Many non-Epson
printers have an Epson-emulation mode. HP PCL printers include the
following:
• HP ThinkJet
• HP LaserJet
• HP PaintJet
• HP DeskJet
• HP QuietJet
You can connect your printer to the logic analyzer using HP-IB,
RS-232-C, or the parallel printer port. The logic analyzer can only
print to printers directly connected to it. It cannot print to a
networked printer on the LAN.

To connect to an HP-IB printer
To connect to an HP-IB printer
Printers connected to the logic analyzer over HP-IB must support HP-IB and
Listen Always. When controlling a printer, the analyzer’s HP-IB port does not
respond to service requests (SRQ), so the SRQ enable setting does not have
any effect on printer operation.
Turn off the analyzer and the printer, and connect an HP-IB cable
1
from the printer to the HP-IB connector on the analyzer rear panel.
2 Turn on the analyzer and printer.
3 Make sure the printer is set to Listen Always or Listen Only.
For example, the figure below shows the HP-IB configuration switches for an
HP-IB ThinkJet printer. For the Listen AlwaysListen Always mode, move the second
switch from the left to the 1 position. Because the instrument doesn’t
respond to SRQ EN (Service Request Enable), the position of the first switch
doesn’t matter.
