1.1 Main Functions
The AD8000 is an integrated multi-functional analyzer that eliminates the
need to carry and learn multi instrument. Except spectrum analysis
function, the AD8000 is also configured functions including power
measurement, occupied bandwidth measurement, interference analyzer,
tracking generator and a high accuracy GPS receiver for location stamping.
The bright 6.5-inch color display provides visibility even in hard light. Built-
in Li-Ion battery can work more than 3.5 hours.
The internal 1G flash memory is large enough to store approximately 2,000
traces or setup files. Measurements data and setup files can also be stored
in a USB flash disk or transferred to PC via the LAN cable.
Workbench software is based on PC platform. It could generate
measurement report, check and manage data and history data, and analyze
cursors, limit line, measurement curve and etc.
This device is produced according to ISO9001 international quality
management system standard by AD INSTRUMENTS. The ISO9001 quality
system was registered and certificated in 1996.
1.2 Preventive Maintenance
AD8000 series preventive maintenance includes the unit surface cleaning, RF
connectors and all accessories cleaning. Clean unit surface with a soft, lint-
free cloth dampened with water.
Clear the RF connectors and center pins with a cotton swab dampened with
denatured alcohol. The fingers of the N(f) connectors and the pins of the
N(m) connectors should be unbroken and uniform in appearance. If you are
unsure whether the connectors are undamaged, gauge the connectors to
confirm that the dimensions are correct. The test port cable should be
uniform in appearance, and not stretched, kinked, dented, or broken.
Caution: To avoid damaging the display or case; do not use solvents or
abrasive cleaners.

1.3 Annual Inspection & Calibration
All brenches and offices of AD INSTRUMENTS are responsible for the
annual maintenance and calibration to ensure the proper use. It is
suggested that users do the maintenance and calibration regularly.
1.4 Protection of ESD
AD8000 series, like other high performance instruments, is susceptible to
electrostatic discharge (ESD) damage. Coaxial cables and antennas often
build up a static charge, which may damage the AD8000 input circuitry.
AD8000 operators must be aware of the potential for ESD damage and take
all necessary precautions.
It is recommended to discharge the static by connecting a short or load
device to the cable or antenna before connecting them to AD8000. It is
important to remember that the operator may also carry a static charge
that can cause damage. Following the practices outlined in the above
standards will ensure a safe environment for both personnel and equipment.
1.5 Battery Replacement
The battery can be replaced without the use of any tool. The battery
compartment is located on lower side of rear (when you are facing the
measurement display). Wring out two screws, slide the cover down and
remove the battery. Installation is the opposite of removal.
Fig. 1-1 Battery Replacement
Note: Ensure the correct connection of battery joints and power lines,
otherwise connection would fail.

Before using the spectrum analyzer, the battery should be charged. AC/DC
power adaptor and vehicle cigarette ligter 12VDC adaptor could be used.
1.6 Carrying Bag
The AD8000 can be operated in the soft carrying bag. On the back of the
case there is a large storage pouch for accessories and power supply.
To install the instrument into the soft carrying case:
1. The front panel of the case is secured with hook-and-loop fasteners.
Fully close the front panel of the case. When closed, the front panel
supports the shape of the case while you are inserting the AD8000.
2. Place the soft carrying case face down on a stable surface, with the
front panel fully closed and laying flat.
3. Open the bag from the top.
4. Put the device in considering the position of the device connector.
5. Put on the back cover.
NOTE: Use only batteries, adapters, and chargers provided with this
instrument.
Warning: When using the Vehicle charger, Make sure that the supply is
rated for a minimum of 60 Watts at 12 VDC, and the socket is clean without
any dirt or debris. If the adapter plug becomes hot to the touch during
charging, Please discontinue using immediately.
NOTE: AD INSTRUMENTS recommends removing the battery for long-term
storage of the instrument.
