The following safety symbols are used throughout this manual. Familiarize yourself with
each of the symbols and its meaning before operating this instrument.
CAUTION
WARNING
Caution denotes a hazard. It calls attention to a procedure that, if not
correctly performed or adhered to, could result in damage to or destruction of
the instrument. Do not proceed beyond a caution note until the indicated
conditions are fully understood and met.
Warning denotes a hazard. It calls attention to a procedure which, if

General Safety Considerations
Safety Earth Ground
WARNING
This is a Safety Class I product (provided with a protective earthing
ground incorporated in the power cord). The mains plug shall only
be inserted in a socket outlet provided with a protective earth
contact. Any interruption of the protective conductor, inside or
outside of the instrument, will make the instrument dangerous.
Intentional interruption is prohibited.

This product is designed for use in Installation Category II and Pollution
Degree 2 per IEC 1010 and 664 respectively.
Make sure that the analyzer line voltage selector switch is set to the voltage
of the power supply and the correct fuse is installed.
Always use the three-prong AC power cord supplied with this product. Failure
to ensure adequate grounding by not using this cord may cause product
damage.
If this product is to be energized via an autotransformer make sure the
common terminal is connected to the neutral (grounded side of the mains
supply).

WARNING
WARNING
WARNING
These servicing instructions are for use by qualified personnel only.
To avoid electrical shock, do not perform any servicing unless you
are qualified to do so.
The opening of covers or removal of parts may expose dangerous
voltages. Disconnect the instrument from all voltage sources while it
is opened.
Danger of explosion if battery is incorrectly replaced. Replace only
with the same or equivalent type recommended. Discard used
batteries according to manufacturer’s instructions.
Procedures described in this document may be performed with
power supplied to the product while protective covers are removed.
Energy available at many points may, if contacted, result in personal
injury.
The power cord is connected to internal capacitors that may remain
live for 10 seconds after disconnecting the plug from its power
supply.
For continued protection against fire hazard, replace line fuse only
with same type and rating. The use of other fuses or material is
prohibited.
WARNING
The detachable power cord is the instrument disconnecting device.
It disconnects the mains circuits from the mains supply before other
parts of the instrument. The front panel switch is only a standby
switch and is not a LINE switch (disconnecting device).

N5230A Electrostatic Discharge Protection
Electrostatic Discharge Protection
Protection against electrostatic discharge (ESD) is essential while removing assemblies
from or connecting cables to the network analyzer. Static electricity can build up on your
body and can easily damage sensitive internal circuit elements when discharged. Static
discharges too small to be felt can cause permanent damage. To prevent damage to the
instrument:
• always have a grounded, conductive table mat in front of your test equipment.
• always wear a grounded wrist strap, connected to a grounded conductive table mat,
having a 1 MΩ resistor in series with it, when handling components and assemblies or
when making connections.
• always wear a heel strap when working in an area with a conductive floor. If you are
uncertain about the conductivity of your floor, wear a heel strap.
• always ground yourself before you clean, inspect, or make a connection to a
static-sensitive device or test port. You can, for example, grasp the grounded outer shell
of the test port or cable connector briefly.
• always ground the center conductor of a test cable before making a connection to the
analyzer test port or other static-sensitive device. This can be done as follows:
1. Connect a short (from your calibration kit) to one end of the cable to short the center
conductor to the outer conductor.
2. While wearing a grounded wrist strap, grasp the outer shell of the cable connector.
3. Connect the other end of the cable to the test port and remove the short from the
cable.
Figure 1-1 shows a typical ESD protection setup using a grounded mat and wrist strap.
Refer to “ESD Supplies” on page 6-41 for part numbers.

“Upgrade Kits” on page 6-41 for a complete list of available kits.
Option 010, Time Domain
An Option 010 analyzer can display the time domain response of a network or test device
by calculating the inverse Fourier transform of the frequency domain response. This
calculation allows the Option 010 analyzer to show the response of a test device as a
function of time or distance. In time domain, the magnitude and location of a discontinuity
and the characteristics of individual transmission paths of a network or test device can be
determined. Time domain operation retains all the accuracy of active error correction.
Option 014, Configurable Test Set
This option is included in the active measurement configuration.
An Option 014 analyzer can be configured to measure high-power devices and devices for
high dynamic range.
For a high-power measurement, external amplifiers and high power attenuators or
isolators can be added to complete the test setup. Test port output power up to 1 Watt
(+30 dBm) can be applied to the device under test (DUT).
Additionally, there is an external reference input that allows the external amplifier’s
frequency response and drift to be ratioed out.

Analyzer Options Available N5230A
For high dynamic range measurements, front panel jumpers are moved to reverse the
signal path through one of the couplers, allowing for a 15 dB improvement in transmitted
signal sensitivity in one direction only. Jumpers are installed on both ports allowing the
user to choose a measurement in either the forward or reverse direction.
Option 080, Frequency Offset Mode
This upgrade enables the additional firmware necessary to make frequency offset
measurements.
Option 1E1, Source Attenuators
This option is included in the active measurement configuration.
This option adds a 60-dB step attenuator in the signal path of each of the measurement
ports. These step attenuators are used to adjust the power level (in 10 db steps) to the
device under test (DUT) without changing the power in the reference path.
Option F20, 20 GHz Frequency Range
This is a 2-port network analyzer with an upper frequency limit of 20 GHz.
Option F40, 40 GHz Frequency Range
This is a 2-port network analyzer with an upper frequency limit of 40 GHz.
Option F50, 50 GHz Frequency Range
This is a 2-port network analyzer with an upper frequency limit of 50 GHz.
Option 1CP, Rack Mount Flange Kit for Instruments with Handles
Option 1CP provides a rack mount kit that contains a pair of flanges (cut to adapt to
handles), rack mount rails, and the necessary hardware to mount the analyzer in an
equipment rack with 482.6 mm (19 inches) horizontal spacing.
Additional kits may be ordered from Agilent. Refer to “Rack Mount Kits and Handle Kits”
on page 6-41 for the part numbers.
Option 1CM, Rack Mount Flange Kit for Instruments without Handles
Option 1CM provides a rack mount kit that contains a pair of flanges, rack mount rails,
and the necessary hardware to mount the analyzer in an equipment rack with 482.6 mm
(19 inches) horizontal spacing.
Additional kits may be ordered from Agilent. Refer to “Rack Mount Kits and Handle Kits”
on page 6-41 for the part numbers.

Shipping Your Analyzer to Agilent for Service or Repair
IMPORTANT
Agilent Technologies reserves the right to reformat or replace the internal
hard disk drive in your analyzer as part of its repair. This will erase all user
information stored on the hard disk. It is imperative, therefore, that you
make a backup copy of your critical test data located on the analyzer’s hard
disk before shipping it to Agilent for repair.
If you wish to send your network analyzer to Agilent Technologies for service or repair:
• Include a complete description of the service requested or of the failure and a
description of any failed test and any error message.
• Ship the analyzer using the original or comparable antistatic packaging materials.
• Contact Agilent for instructions on where to ship your analyzer. Refer to “Contacting
Agilent” on page 2-10.
