Safety Notices
A CAUTION notice denotes a hazard. It
calls attention to an operating
procedure, practice, or the like that, if
not correctly performed or adhered to,
could result in damage to the product
or loss of important data. Do not
proceed beyond a CAUTION notice until
the indicated conditions are fully
understood and met.
A WARNING notice denotes a hazard.
It calls attention to an operating
procedure, practice, or the like that, if
not correctly performed or adhered to,
could result in personal injury or
death. Do not proceed beyond a
WARNING notice until the indicated
conditions are fully understood and
met.
CAUTION
WARNING

4
The following general safety precautions
must be observed during all phases of
operation of this instrument. Failure to
comply with these precautions or with
specific warnings elsewhere in this manual
violates safety standards of design,
manufacture, and intended use of the
instrument.
Keysight Technologies assumes no liability
for the customer's failure to comply with
these requirements.
Before operation, review the instrument and
manual for safety markings and instructions.
You must follow these to ensure safe
operation and to maintain the instrument in
safe condition.
This product is a Safety Class 1 instrument
(provided with a protective earth terminal).
The protective features of this product may
be impaired if it is used in a manner not
specified in the operation instructions.
All Light Emitting Diodes (LEDs) used in this
product are Class 1 LEDs as per IEC 60825-1.
This instrument is intended for indoor use in
an installation category II, pollution degree 2
environment. It is designed to operate at a
maximum relative humidity of 95% and at
altitudes of up to 2000 meters.
Refer to the specifications tables for the ac
mains voltage requirements and ambient
operating temperature range.
Verify that all safety precautions are taken.
The power cable inlet of the instrument
serves as a device to disconnect from the
mains in case of hazard. The instrument
must be positioned so that the operator can
easily access the power cable inlet. When
the instrument is rack mounted the rack
must be provided with an easily accessible
mains switch.
To minimize shock hazard, the instrument
chassis and cover must be connected to an
electrical protective earth ground. The
instrument must be connected to the ac
power mains through a grounded power
cable, with the ground wire firmly connected
to an electrical ground (safety ground) at the
power outlet. Any interruption of the
protective (grounding) conductor or
disconnection of the protective earth
terminal will cause a potential shock hazard
that could result in personal injury.
Do not operate the instrument in the
presence of flammable gases or fumes.
Operating personnel must not remove
instrument covers. Component replacement
and internal adjustments must be made only
by qualified personnel.
Instruments that appear damaged or
defective should be made inoperative and
secured against unintended operation until
they can be repaired by qualified service
personnel.

Indicates warning or caution. If you see this
symbol on a product, you must refer to the
manuals for specific Warning or Caution
information to avoid personal injury or damage to
the product.

Power Switch
The front panel switch is used to switch on and off the instrument.
When the front panel switch is off, the instrument is in standby mode. The
instrument is disconnected from the AC line power only by disconnecting
the power cord.
USB
The Front Panel contains a USB host connector. It is intended to connect
USB drives to store instrument states and waveforms on an external
memory.
Menu Softkeys
The five keys below the main display screen are called softkeys (software-
controlled keys). The current function of each softkey is indicated in the
corresponding box on the display.
Some softkeys hold additional symbols to indicate that they provide
extended functionality.
 Yellow Triangles: These are visible on the five softkeys on the
Front Panel. The yellow triangles indicate that there are more choices
further, and keep pressing to view the available options.
 White Rectangles: Indicate that by pressing them, you can
enter into another screen.
The following examples explain the above-mentioned points:
Pressing this softkey will toggle between
Frequency and Period representation.
Pressing this softkey will open the output
configuration screen.
More Key
Pressing the MORE key switches to the next layer of softkeys on the current
screen.
