Safety Precautions
The following safety precautions should be observed before using this product and any associated instrumentation. Although some
instruments and accessories would normally be used with non-hazardous voltages, there are situations where hazardous conditions may
be present.
This product is intended for use by qualified personnel who recognize shock hazards and are familiar with the safety precautions required
to avoid possible injury. Read and follow all installation, operation, and maintenance information carefully before using the product. Refer
to the user documentation for complete product specifications.
If the product is used in a manner not specified, the protection provided by the product warranty may be impaired.
The types of product users are:
Responsible body is the individual or group responsible for the use and maintenance of equipment, for ensuring that the equipment is
operated within its specifications and operating limits, and for ensuring that operators are adequately trained.
Operators use the product for its intended function. They must be trained in electrical safety procedures and proper use of the instrument.
They must be protected from electric shock and contact with hazardous live circuits.
Maintenance personnel perform routine procedures on the product to keep it operating properly, for example, setting the line voltage or
replacing consumable materials. Maintenance procedures are described in the user documentation. The procedures explicitly state if the
operator may perform them. Otherwise, they should be performed only by service personnel.
Service personnel are trained to work on live circuits, perform safe installations, and repair products. Only properly trained service
personnel may perform installation and service procedures.
Keithley Instruments products are designed for use with electrical signals that are rated Measurement Category I and Measurement
Category II, as described in the International Electrotechnical Commission (IEC) Standard IEC 60664. Most measurement, control, and
data I/O signals are Measurement Category I and must not be directly connected to mains voltage or to voltage sources with high transient
over-voltages. Measurement Category II connections require protection for high transient over-voltages often associated with local AC
mains connections. Assume all measurement, control, and data I/O connections are for connection to Category I sources unless otherwise
marked or described in the user documentation.
Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on cable connector jacks or test fixtures. The
American National Standards Institute (ANSI) states that a shock hazard exists when voltage levels greater than 30V RMS, 42.4V peak,
or 60VDC are present. A good safety practice is to expect that hazardous voltage is present in any unknown circuit before measuring.
Operators of this product must be protected from electric shock at all times. The responsible body must ensure that operators are
prevented access and/or insulated from every connection point. In some cases, connections must be exposed to potential human contact.
Product operators in these circumstances must be trained to protect themselves from the risk of electric shock. If the circuit is capable of
operating at or above 1000V, no conductive part of the circuit may be exposed.
Do not connect switching cards directly to unlimited power circuits. They are intended to be used with impedance-limited sources. NEVER
connect switching cards directly to AC mains. When connecting sources to switching cards, install protective devices to limit f
and voltage to the card.
Before operating an instrument, ensure that the line cord is connected to a properly-grounded power receptacle. Inspect the connecting
cables, test leads, and jumpers for possible wear, cracks, or breaks before each use.
ault current
11/ 07
When installing equipment where access to the main power cord is restricted, such as rack mounting, a separate main input power
!
disconnect device must be provided in close proximity to the equipment and within easy reach of the operator.
For maximum safety, do not touch the product, test cables, or any other instruments while power is applied to the circuit under test.
ALWAYS remove power from the entire test system and discharge any capacitors before: connecting or disconnecting cables or jumpers,
installing or removing switching cards, or making internal changes, such as installing or removing jumpers.
Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth) ground. Always
make measurements with dry hands while standing on a dry, insulated surface capable of withstanding the voltage being measured.
The instrument and accessories must be used in accordance with its specifications and operating instructions, or the safety of the
equipment may be impaired.
Do not exceed the maximum signal levels of the instruments and accessories, as defined in the specifications and operating information,
and as shown on the instrument or test fixture panels, or switching card.
When fuses are used in a product, replace with the same type and rating for continued protection against fire hazard.
Chassis connections must only be used as shield connections for measuring circuits, NOT as safety earth ground connections.
If you are using a test fixture, keep the lid closed while power is applied to the device under test. Safe operation requires the use of a lid
interlock.
If a screw is present, connect it to safety earth ground using the wire recommended in the user documentation.
The symbol on an instrument indicates that the user should refer to the operating instructions located in the user documentation.
The symbol on an instrument shows that it can source or measure 1000V or more, including the combined effect of normal and
common mode voltages. Use standard safety precautions to avoid personal contact with these voltages.
The symbol on an instrument shows that the surface may be hot. Avoid personal contact to prevent burns.
The symbol indicates a connection terminal to the equipment frame.
If this symbol is on a product, it indicates that mercury is present in the display lamp. Please note that the lamp must be properly
disposed of according to federal, state, and local laws.
The WARNING heading in the user documentation explains dangers that might result in personal injury or death. Always read the
associated information very carefully before performing the indicated procedure.
The CAUTION heading in the user documentation explains hazards that could damage the instrument. Such damage may invalidate the
warranty.
Instrumentation and accessories shall not be connected to humans.
Before performing any maintenance, disconnect the line cord and all test cables.
To maintain protection from electric shock and fire, replacement components in mains circuits - including the power transformer, test leads,
and input jacks - must be purchased from Keithley Instruments. Standard fuses with applicable national safety approvals may be used if
the rating and type are the same. Other components that are not safety-related may be purchased from other suppliers as long as they
are equivalent to the original component (note that selected parts should be purchased only through Keithley Instruments to maintain
accuracy and functionality of the product). If you are unsure about the applicability of a replacement component, call a Keithley Instruments
office for information.
To clean an instrument, use a damp cloth or mild, water-based cleaner. Clean the exterior of the instrument only. Do not apply cleaner
directly to the instrument or allow liquids to enter or spill on the instrument. Products that consist of a circuit board with no case or chassis
(e.g., a data acquisition board for installation into a computer) should never require cleaning if handled according to instructions. If the
board becomes contaminated and operation is affected, the board should be returned to the factory for proper cleaning/servicing.

and holding the key for a few seconds.
•Generate a DC voltage level: Instructions are provided for you to enable the DC-only
voltage level option.
•Generate a modulated waveform: Follow the instructions provided to produce a
modulated waveform.
•Default state resetting: Instructions enable you to return the instrument to the factory
default state.
•View a waveform in Graph Mode: This information details use of the graph mode.
•Synchronize multiple instruments: Follow the detailed instructions for connecting multiple
instruments.
•KEITHLEY Technical Support: Keithley Instruments technical support contact information
is located here.
Utility menu key
The Utility menu key allows access to the following settings and parameters:
•DC: The DC offset voltage setting can be changed from the Utility menu. The default DC
offset voltage is zero (0) volt for all functions.
•Sync: The sync out signal can be turned on and off from the Utility menu. All standard
output functions (with the exception of DC and noise) can be associated with a sync-out
signal. The signal is delivered at the Sync connector on the front panel.
•Output Setup: This key contains a number of different parameters. The output termination
setting can be changed, voltage auto ranging can be turned on and off, waveform polarity
can be specified as normal or inverted, the phase offset of the output waveform can be
adjusted, and lastly, the 10 MHz time base output can be turned on and off.

•I/O: The general purpose interface bus (GPIB) and local area network (LAN) remote
interface configurations can be set up through the Utility menu. In addition, you can view
the universal serial bus (USB) interface identification here.
•PATT Mode: You can set up pattern output through the Utility menu. Pattern output
provides five built-in patterns and up to four user-defined patterns that are stored in
nonvolatile memory.
•System: Several system parameters can be accessed through the Utility menu. The error
beeper and sound can be turned on and off, and the calibration and self-test menus can
be entered.
Store/Recall menu key
The Model 3390 has five storage locations in nonvolatile memory to store instrument state. The
stored instrument state holds all the parameters for the selected function, including the
waveform, frequency, DC offset, amplitude, duty cycle, symmetry, modulation type, and
modulation parameters.
The instrument may also be reset to its factory default settings.
Modulation, Sweep, and Burst keys
Modulation, sweep, and burst operations for the Model 3390 can be waveform-specific. The
parameters for each operation are found in Section 5, Waveform Output Operations.
Waveform selection keys
The Model 3390 has five types of standard waveforms: Sine, square, ramp, pulse, and noise
(refer to Section 5, Waveform Output Operations for detailed information). In addition, there are
five built-in arbitrary waveforms.
