SAFETY INFORMATION
I WARNING I
Any interruption of the protective grounding conductor (inside or outside the instrument) or discon-
necting the protective earth terminal will cause a potential shock hazard that could result in personal
injury. (Grounding one conductor of a two conductor outlet is not sufficient protection.)
Whenever it is likely that the protection has been impaired, the instrument must be made inoperative
and be secured against any unintended operation.
If this instrument is to be energized via an autotransformer (for voltage reduction) make sure the common
terminal is connected to the earthed pole terminal (neutral) of the power source.
Instructions for adjustments while covers are removed and for servicing are for use by service-trained
personnel only. To avoid dangerous electricshock, do not perform such adjustments or servicing unless
qualified to
do so.
For continued protection against fire, replace the line fuse(s) only with 250V fuse(s) of the same current
rating and type (for example, normal blow, time delay). Do not use repaired fuses or short circuited
fuseholders.

1-10. DESCRIPTION
1-11. The Hewlett-Packard Models 5384A and 5385A
are
frequency counters that make frequency and
period measurements. The HP 5384A has a frequency
range of 10 Hz to 225 MHz, and the HP 5385A has a
frequency range of 10Hz to 1000 MHz. Bothcounters
are microcomputer based instruments with adata bus
port for remote operation through either HP-IL or
HP-IB.
1-12. Both counters have "A" and "B" input chan-
nels with BNC type connectors.
1-13.
Above the "A" and "B" input connectors is a
dual purpose control that allows you to either set the
trigger level of Channel A or adjust the input attenu-
ation of Channel B.
1-14. A 100 kHz low pass filter can be toggled in or
out of the Channel A signal path on either counter.
1-15. Measurement display and mode annunciators
are shown
on a 12-character alphanumeric liquid
crystal display (LCD). Frequencyand period measure-
ments are displayed
in engineering format, with three
alpha characters used to designate units, e.g., MHz.
The display will also give you brief messages and
diagnostic prompts.
1-16. The
HP 5384A and HP 5385A are designed so
you may either rack mount or stack them.
1-17. A 10 MHz reference oscillator output is in-
cluded in both counters. The connector for the 10
MHz output may also be used as an external10 MHz
reference oscillator input connection.
1-18. Option 001 is a temperature compensated
crystal oscillator (TCXO). TheTCXO is an option in the
HP 5384A and standard in the HP 5385A.
1-19. A jack
for connecting external de power is pro-
vided on the rear panel and Option 005 battery pack
can be installed
to provide mobility.
1-20. Option 003 is the Hewlett-Packard Interface
Loop (HP-IL) for remote control of the counters by
battery operated controllers such
as the HP41C/CV
hand held controller.
1-21. Option 004 is an ovenized oscillator that
provides a high stability
time base giving substan-
tially higher accuracy over variations in time and
temperature.
1-22.
Option 005 is a battery pack that provides
portable operation of the HP 5384A or HP 5385A.
1-23. HP-IB is the Hewlett-Packard Interface Bus for
remote control of the counters by computers and
controllers. It is a standard feature in the instrument.
1-1

HP 5384A and HP 5385A
General
Information
1-24. The HP-IB, (Hewlett-Packard Interface Bus) is
Hewlett-Packard's implementation of IEEE Standard
488-1978 and ANSI Standard
MC 1.1. HP-IB is a high-
speed parallel interface bus. All devices on the bus are
capable
of being addressed at one time. However,
only one device mayrespond atatime. A controller is
used to command which device responds. (The HP
5384A
or HP 5385A with HP-IB would make measure-
ments and
return data upon commands from a
controller.)
1-25. The counter can be configured for either
HP-IB or HP-IL, not both.
1-26. HP-IB or HP-IL allows the HP 5384A and HP
5385A to output data to other devices or, on a more
complex level, respond to remote programming in-
structions to make a specific type of measurement,
trigger that measurement, then read the result and
send the reading back
to the controller, or to another
device on the interface.
1-27. OPTIONS
1-28. Option 001 is a Temperature Compensated
Crystal Oscillator (TCXO)
for HP 5384A. The TCXO is a
10 MHz oscillator, capable of making minor fre-
quency corrections to compensate for temperature
variations.
1-29.
Option 003 is HP-IL, (Hewlett-Packard Inter-
face Loop). HP-IL is a low cost, two-wire serial inter-
face that permits communications from one device to
another. As the name implies, the HP 5384A or HP
5385A is connected in a serial loop structure. Data or
information, in the form of digital messages, travels
from one device to the next in the loop. If the
information is not intended for the counter, the
counter merely passes the information on to the next
device in the loop. If the information is intended for
the counter, the counter responds as directed by the
information.
1-30. Option 004 is an ovenized oscillator that gives
the HP 5384A and HP 5385A increased accuracy by
providing a more stable time base reference signal.
The oven maintains
the crystal at a constant elevated
temperature for increased stability over the ambient
temperature range.
1-31.
Option 005 Battery Pack is a lead acid type
battery that provides at least 3 hours of operation
while the counter is disconnected from the power
line. Operation time is reduced to approximately
1-hour when operated with HP-IB.

If an instrument contains an Option 005 Battery
Pack as well as the ovenized oscillator, the
ovenized oscillator
will draw power from the
battery pack if no external ac or de power is
applied. Power will be drawn from the battery
pack
continuously with the instrument in either
ON or STBY (standby) positions.
1-32. The battery pack
will be recharged in 16 hours
if the counter is in the standby mode and either the
line cord is attached or external de is applied through
the rear panel jack. The battery will trickle charge
while the counter is being used and is connected to
either an ac power line or external de.
1-33. INSTRUMENT IDENTIFICATION
1-34. Hewlett-Packard instruments have a 2-section,
10-character serial number (OOOOAOOOOO), which is
located on the rear panel. The four-digit serial prefix
identifies the instrument changes.
If the serial prefix of
your instrument differs from thatlisted on thetitlepage
of this manual, there are differences between this
manual and
your instrument. Instruments having
higher serial prefixes are covered with a
"Manual
Changes" sheet included with this manual. If the
change sheet
is missing, contact the nearest Hewlett-
Packard Sales and Support Office listed at the back of
this manual. Instruments having a lower serial prefix
than that listed
on the title page are covered in Section
VII.

INSTALLATION
2-1. INTRODUCTION
2-2. This section contains information for unpack-
ing, inspection, storage, and installation.
2-3. UNPACKING AND INSPECTION
2-4. If the shipping carton is damaged, inspect the
instrument for visible damage (scratches, dents, etc.).
If the instrument is damaged, notify the carrier and
the nearest Hewlett-Packard Sales and Service Office
immediately (offices are listed at the back of this
manual). Keep
the shipping and packing material for
the carrier's inspection. The Hewlett-Packard Sales
and Service Office will arrange for repair or replace-
ment of your instrument without waiting for the claim
against
the carrier to be settled.
2-5. PREPARATION FOR USE
[~
Before connecting the instrument to ac
power lines, be sure that the voltage selector
is properly positioned as described below.
2-6. POWER REQUIREMENTS
2-7. The counter has the following ac power
requirements:
115V, +10%, -25%, 48-66 Hz single phase
230V, +10%, -15%, 48-66 Hz single phase
115V, +10%, -10%, 380-420 Hz single phase
A2-8. LINE VOLTAGE SELECTION
2-9. The power line voltage is selected by the
position of the LINE SELECT switch on the rear panel.
Sliding the switch
to the left selects 115V operation,
sliding the switch to the right selects 230V operation.
The voltages available are printed on the switch. The
specific voltage selected
will be visible on the LINE
SELECT switch, as shown in Figure 2-1. Before
applying
power, verify that the LINE SELECT switch is
properly set for the desired acsupplyvoltageand that
the correct fuse is installed.
2-10. AC Line Fuse Selection
2-11. The ac line fuse is not accessible from the
outside of the cabinet. The cabinet should be opened
only by qualified service personnel. The correct fuse
value
is 250 mAT/250V Slow Blow for 115V or 230V
operation.

screwdriver
to remove the fuse from the fuseholder.
Press in slightly and turn counterclockwise, until the
fuse carrier springs free. Replace the fuse in the fuse
carrier and reinstall byinserting and
turning clockwise.
Be sure to install the correct fuse value; 2 N250V fast
blow.
2-14. The de fuse is the main protective device for the
instrument. The de fuse will
blow whether the de
current source
is theoptional batterypack, power from
the external de power jack, or the built-in ac power
supply.
2-15. Power Cable
2-16. The counter is shipped with athree-wire power
cable. When the cable is connected to an appropriate
ac power source, this cable connects the instrument
chassis to earth ground. The type of power cable plug
shipped with each instrument depends on the country

of the power cable and plug configurations available.
I WARNING I
BEFORE ENERGIZING THIS INSTRUMENT, THE
PROTECTIVE EARTH TERMINAL OF THIS
INSTRUMENT MUST BE CONNECTED TO THE
PROTECTIVE CONDUCTOR OF THE (MAINS)

2-17. HP-18 Interconnections
2-18. HEWLETT-PACKARD INTERFACE BUS.The
counter with HP-IB is compatible with the Hewlett-
Packard Interface Bus. Interconnection data concern-
ing the rear panel HP-IB connector is provided in
Figure 2-3. This connector is compatible with the HP
10833A/B/C/D cables. (See Table 2-1 for cable de-
scriptions).The HP-IB system allows interconnection
of up to 15 (including the controller) HP-IB
compatible instruments.
Table 2-1. HP-18 Cable Descriptions
HP Model Cable Length
10833A 1
metre (3.3 feet)
108338 2 metres (6.6 feet)
10833C 4 metres (13.2 feet)
108330 0.5 metres (1.6 feet)
2-19. The HP-IB cables have identical "piggy-back"
connectors on both ends so that several cablescan be
connected to a single source without special adapters
or switch boxes. System components and devices may
be
connected in virtually any configuration desired.
There must,
of course, be a path from the calculator
(or other controller) to every device operating on the
bus. As a practical matter, avoid stacking more than
three or four cables on any one connector. If the stack
gets
too large, the force on the stack produces great
leverage
which can damage the connector mounting.
Be sure each connector is firmly (finger tight) screwed
in place to keep it from working loose during use.
2-20. CABLE LENGTH RESTRICTIONS. To achieve
design performance with the HP-18, the proper voltage
levels and
timing relationships must be maintained. If
the system cable is too long, the lines cannot be driven
properly, and the system will fail
to perform properly.
Therefore, when interconnecting
an HP-IB system, it is
important to observe the following rules.
a. The total cable length for the system must be less
than or equal to 20 metres (65.6 feet).
b. The total cable length for thesystem must be
less
than or equal to 2 metres (6.6 feet) times the total
number of devices connected to the bus.
c. The total number of instruments connected to
the bus must not exceed 15.
2-21. HP-18 Talk/Listen Address Switch
2-22. The HP 5384A and HP 5385A provide a rear
panel HP-IB instrument address selection switch. This
switch determines the
mode of remote operation as
