Safety Information
General Safety Considerations
General Safety Considerations
If the signal generator is not used as specified, the protection provided by the
equipment could be impaired. The signal generator must be used in a normal
condition only, in which all means for protection are intact.
Personal injury may result if the signal generator covers are removed. There are no
operator serviceable parts inside. To avoid electrical shock, refer servicing to
qualified personnel.
Safety of any system incorporating the equipment is the responsibility of the
assembler of the system.

Checking the Shipment
Checking the Shipment
1. Inspect the shipping container for damage.
Signs of damage can include a dented or torn shipping container or
cushioning material that indicates signs of unusual stress or compacting.
2. Carefully remove the contents from the shipping container and verify that
your order is complete.
The following items are included with each signal generator:
— Getting Started Guide
— three-prong AC power cord specific to geographic location
3. Verify that the options/accessories you ordered are included with the
shipment by checking the serial number label on the rear of the signal
generator and the packing literature included with the shipment.
See also, “Ordering Accessories” on page 23.
4. If a pre-installed software license is part of the instrument order, verify its
installation using the directions outlined in “Verifying Pre-Installed
Software License” on page 15.
14 Keysight CXG, EXG, and MXG X-Series Signal Generators Getting Started Guide
Getting Started
Verifying Pre-Installed Software License
Veri f ying Pre-I nstalled Software License
If you purchased a signal generator where the order included the
pre-installation of a fixed perpetual Signal Studio license (N76xx), or a Test
Management Environment (TME) software license (N78xxA), or both, verify the
license installation using the following key path:
Utility > Instrument Info > Options Info
This opens a menu with the choices: Instrument Options, Auxiliary
Software Options, and Waveform Licenses. To view the license, press the
appropriate menu key:
— For a Signal Studio license, press Instrument Options.
— For the TME license, press Auxiliary Software Options.
If a license is pre-installed, the software for that license still needs to be
downloaded onto your PC. Use the following links to access the software for
download and installation:
— Signal Studio software: www.keysight.com/find/signalstudio
—TME software: www.keysight.com/find/calibrationsoftware
If the software license(s) was ordered with the instrument for pre-installation
and it does not show in the instrument, please contact Keysight Technologies:

Meeting Environmental and Electrical Requirements
Meeting Environmental and Electrical Requirements
To avoid the loss of data, GPIB settings, or current user instrument states that
have not been permanently saved to non-volatile memory, the signal generator
should always be powered down either via the signal generator's front panel
power button or the appropriate SCPI command. Signal generator's installed in
rack systems and powered down with the system rack power switch rather than
the signal generator's front panel switch display a Error -310 due to the signal
generator not being powered down correctly.
The input terminals for this product are classified as Measurement Category
None.

The instruments can operate with mains supply voltage fluctuations up to ± 10%
of the nominal voltage.
Ventilation holes are located on the rear panel and all four sides of the signal
generator cover. To ensure proper air flow through the signal generator, do not
allow these holes to be obstructed.
Rack-mounted units
When installing the instrument(s) into a cabinet, consideration shall be given
to the convection flow into and out of the cabinet. Consideration shall also be
given to the individual instruments to avoid having the heated discharge of one
instrument, now becoming the cooling intake air for another instrument.
Another area of concern is verification that the maximum ambient operating
temperature of the instrument(s) is not exceeded by cabinet installation.
Keysight recommends forced air convection whenever an instrument(s) are
installed in a cabinet and further recommends that the maximum operating
temperature of the cabinet be reduced 10°C from the lowest, of the maximum
operating temperature of a single instrument.
If there are any concerns or special requirements a Keysight Field Engineer
should be consulted to assure instrument(s) temperature compliance and
performance.
Line Setting Requirements
The signal generator has autoranging line voltage input; ensure that the supply
voltage is within the specified range.
Voltage: 100/120 volts nominal
Frequency: for 100/120 volts: 50/60/400 Hz nominal
Power: 160 W maximum (N5171B & N5181B)
220/240 volts nominal
for 220/240 volts: 50/60 Hz nominal
300 W maximum (N5166B, N5172B & N5182B)
280 W maximum (N5173B & N5183B)

Getting Started
Meeting Environmental and Electrical Requirements
Connecting the AC Power Cord
This is a Safety Class 1 Product provided with a protective earth ground
incorporated into the power cord. The front panel switch is only a standby
switch; it is not a line switch. The AC power cord is the disconnecting device
that disconnects the signal generator mains circuits from the mains supply.
Alternatively, an external switch or circuit breaker, readily identifiable and
easily reached by the operator, may be used as a disconnecting device.
The instrument shall be set flat in its normal use position so that the detachable
power cord is readily identifiable and is easily reached by the operator. It shall not
be placed on the four feet of the rear panel in normal use.
The mains plug shall be inserted only in a socket outlet provided with a protective
earth contact. Always use the three-prong AC power cord supplied with the signal
generator. Personal injury can occur if there is any interruption of the protective
conductor inside or outside of the signal generator. Intentional interruption is
prohibited.
The mains wiring and connectors shall be compatible with the connector used in
the premise electrical system. Inadequate earth grounding can damage the signal
generator. Always use the three-prong AC power cord supplied with the signal
generator.
To avoid possible instrument damage, use the Keysight supplied power cord or
one with same or better electrical rating.
Connect the AC power cord as follows:
1. Ensure that the power cord is not damaged.
2. Install the signal generator so that one of the following items is readily
identifiable and easily reached by the operator: AC power cord, alternative
switch, or circuit breaker.
3. Insert the mains plug into a socket outlet provided with a protective earth
grounding.
