DESCRIPTION
1-5. The standard 5328A mainframemeasuresfrequency,period, periodaverage, time interval,
time interval average, and ratio. A totalize function
is also provided. The capabilities of the
instrumentareexpanded
(as shown inTable 1-3) by installingtheoptionsdescribedinparagraph
1-17. The 5328A providesan 8-digit
(9 withOption030)LED display, displaystorage, and leading
zero blanking. Decimal point and unit readoutsare displayedautomatically.Two independent
selectable input channelsare provided for time interval measurements. Each inputchannel has
an attenuator, trigger slope selector, level control, ac-dc coupling, and an oscilloscope marker
output. Rear panel connectors provide a gate output, a time base output and an input for an
externalfrequencystandard.An ARM switchonthe rear panelallowsarming by thesignal being
measured (switchOFF) or by another input signal (switch ON).
1-6.
INSTRUMENT IDENTIFICATION
1-7. Hewlett-Packard instrumentshave
a 2-section, 10-character serial number (0000A00000),
which
is locatedon the rear panel. The 4-digit serial prefix identifies instrument changes. Ifthe
serial prefix of your instrument differs from that listedonthetitle pageof this manual, there are
differences betweenthis manualand your instrument. Instrumentshaving higher serial prefixes
are covered with
a "Manual Changes" sheet includedwith this manual. If the change sheet is
missing, contact the nearest Hewlett-Packard Sales and ServiceOffice listed at the back of this
manual.

General Information
1-8.
APPLICATIONS
1-9. Specific applications information
is provided in Section IV. The general application
features of the 5328A are described in the following paragraphs.
1-10. The high sensitivity, frequency range, and signal conditioning controls (seeTable 1-3)
make the 5328A ideally suited for awide range of applications. The direct count feature of the
5328A means thatprescalingtechniques arenotusedtoachievethel00MHzfrequency range(up
to 512 MHzwith Option030). Direct count speed is required inhigh-speed totalizing or system
applications.The dynamic range, inputattenuatorsandtrigger level range (seeTable1-3) permit
measurements to be made on virtually any signal.
1-11. The controlled "arming" feature of the 5328A
is useful inapplications such as burst fre-
quency measurements, and pulse amplitude measurements.
1-12. The optional integrating digital voltmeters measure trigger levels (critical in most time
interval measurements)andexternalvoltages.Thehysteresiscompensation featureofOption040
means that the trigger ievei does notneedresetting when the slope switch changesthe
polaii~~.
1-13. The standard 5328A single-shot resolution of 100 ns meets the requirements for appli-
cations such as mechanical and electromechanical device (relays) timing, time of flight
measurements(ballistics), sonar ranging, radiorangingand navigation.The Option040 provides
increased resolution (to 10 ns) useful inapplications such as computer/peripheral timing mea-
suremnts, logic timing measurements, radar ranging and optical ranging. The delay feature of
Option 040 allows unwanted signals tobe ignored which would otherwise trigger the counter.
1-14. Usingtime interval averaging, time intervalsasshort as loops, with resolutiontolopsmay
be measured. Applications include cable length measurements, phase measurements, logic
timing measurements, and integrated circuit propagation delay measurement.
1-15. Fullbandwidth, sensitivity, and signalconditioningof theChannelA, B(andCforOption
030) input amplifiers
is provided for ratio, totalizing, and scaling measurements.
1-16. The 5328A with Option 011 HP-IB lnterface
is able to output measurement data and be
controlled (fully programmed) via the Hewlett-Packard lnterface Bus (HP-IB). The 5328A
is
interfaced toHP-IB compatibleinstruments, calculators, orcomputers bysimply interconnecting
with an HP-IB cable.
1-17.
