Safety Notes
The following safety notes are used throughout this manual. Familiarize yourself with
each of the notes and its meaning before operating this instrument.
WARNINGWarning denotes a hazard. It calls attention to a procedure which, if
not correctly performed or adhered to, could result in injury or loss
of life. Do not proceed beyond a warning note until the indicated
conditions are fully understood and met.
CAUTIONCaution denotes a hazard. It calls attention to a procedure that, if not
correctly performed or adhered to, would result in damage to or destruction of
the instrument. Do not proceed beyond a caution sign until the indicated
conditions are fully understood and met.

General Safety Considerations
SOFTKEY
WARNINGFor continued protection against fire hazard replace line fuse only
with same type and rating (115V operation: T 5A 125V UL/ 230V
operation: T 4A H 250V IEC). The use of other fuses or material is
prohibited.
WARNINGThis 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 the instrument, is likely to make the instrument dangerous.
Intentional interruption is prohibited.
CAUTIONVentilation Requirements: When installing the instrument in a cabinet,
the convection into and out of the instrument must not be restricted. The
ambient temperature (outside the cabinet) must be less than the maximum
operating temperature of the instrument by 4 °C for every 100 watts
dissipated in the cabinet. If the total power dissipated in the cabinet is
greater than 800 watts, then forced convection must be used.

1. Set the line-voltage selector to the position
that corresponds to the AC power source.
3. Ensure the operating environment meets
the following requirements:
• 0 to 55 °C
2. Ensure the available AC power source

have. If repair is necessary, send the analyzer (and the EEPROM backup
disk) to the nearest Agilent Technologies service center with a description of
any failed test and any error message. Ship the analyzer using the original

Description
Correction constants are stored in EEPROM on the A9 controller assembly. The advantage
of having an EEPROM backup disk is the ability to store all the correction-constant data to
a new or repaired A9 assembly without having to rerun the correction-constant
procedures. The analyzer is shipped from the factory with an EEPROM backup disk which
is unique to each instrument. It is prudent to make a copy of the EEPROM backup disk so
that it can be used in case of failure or damage to the original backup disk.

4. Look at the device response to determine if these are the parameters that you want for
your device measurement. For example, if the trace is noisy you may want to increase
the test port output power (which increases the analyzer input power), reduce the IF
bandwidth, or add averaging. Or, to better see an area of interest, you may want to
change the test frequencies.

Learning to Make Reflection Measurements
Learning to Make Reflection Measurements
This example procedure shows you how to measure the reflection response of a 175 MHz
bandpass filter. The measurement parameter values listed are unique to this particular
test device.
For further measurement examples, refer to the "Making Measurements" chapter in the
User's Guide.
NOTEReflection measurements monitor only one port of a test device. When a test
device has more than one port, you must ensure that the unused port(s) are
terminated in their characteristic impedance (for example, 50Ω or 75Ω). If
you do not terminate unused ports, reflections from these ports will cause
measurement errors. Figure 2-8 on page 2-15 illustrates two ways to
terminate an unused device port with the proper characteristic impedance.
The signal reflected from the device under test is measured as a ratio of the reflected
energy versus the incident energy. It can be expressed as reflection coefficient, return loss,
or standing-wave-ratio (SWR). These measurements are mathematically defined as
follows:
reflection coefficient (Γ)= reflected voltage / incident voltage
= S11 or S22 (magnitude and phase)

3. Follow the prompts shown on the analyzer display to connect and measure an open,

you would connect the female, type-N calibration device. But when you follow the
prompts on the analyzer to measure a short calibration standard, you would select
, or the sex that represents the test port.
NOTETo ensure an accurate error correction, you must connect the calibration
standards to the adapters or cables that you will include in the actual device

Figure 2-10.
The device response indicates that the filter and the analyzer impedances are better
matched within the frequency range of the filter passband than outside the passband.
That is, the reflected signal is smaller within the filter passband than outside the
passband.
In terms of return loss, the value within the passband is larger than outside the
passband. A large value for return loss corresponds to a small reflected signal just as a
large value for insertion loss corresponds to a small transmitted signal.

The amount of power reflected from a device is directly related to the impedance of the
device and the measuring system. Each value of the reflection coefficient (Γ) uniquely
defines a device impedance; Γ = 0 only occurs when the device and analyzer impedance are
exactly the same. The reflection coefficient for a short circuit is: Γ = 1 ∠ 180°. Every other
value for Γ also corresponds uniquely to a complex device impedance, according to the

If You Encounter a Problem
If you have difficulty when installing or using the analyzer, check the following list of
commonly encountered problems and troubleshooting procedures. If the problem that you
encounter is not in the following list, refer to additional troubleshooting sections in the
Service Guide.
Power-Up Problems
If the analyzer display does not light:
• Check that the power cord is fully seated in both the main power receptacle and the
analyzer power module.
• Check that the AC line voltage selector switch is in the appropriate position
(230 V/115 V) for your available power supply.
• Check that the analyzer AC line fuse is not open.
WARNINGFor continued protection against fire hazard, replace the fuse with
the same type and rating.
Refer to Figure 2-17 to remove the fuse from the power module. You can use a
continuity light or an ohmmeter to check the fuse. An ohmmeter should read very close
to zero ohms if the fuse is good. For 115V operation, use Fuse, T 5A 125V, UL listed/CSA
certified to 248 standard (part number 2110-1059). For 230V operation, use Fuse, T 4A
H 250V, built to IEC 127-2/5 standard (part number 2110-1036).
