SPA-900 Series User Manual 2
General Safety Summary
Carefully read the following safety precautions to avoid any personal injury or damage to
the instrument and any products connected to it. To avoid potential hazards, please use the
instrument as specified.
Use Proper AC Power Line
Only the power cord designed for the instrument and authorized by local country should be
used.
Ground the Instrument
The instrument is grounded through the protective earth conductor of the power line. To
avoid electric shock, please make sure the instrument is grounded correctly before
connecting its input or output terminals.
Connect the Probe Correctly.
If a probe is used, do not connect the ground lead to high voltage since it has isobaric
electric potential as the ground.
Look Over All Terminals’ Ratings
To avoid fire or electric shock, please look over all ratings and sign instruction of the
instrument. Before connecting the instrument, please read the manual carefully to gain
more information about the ratings.
Use Proper Overvoltage Protection
Make sure that no overvoltage (such as that caused by a thunderstorm) can reach the
product, or else the operator might be exposed to danger of electrical shock.
Electrostatic Prevention
Operate the instrument in an electrostatic discharge protective area environment to avoid
damages induced by static discharge. Always ground both the internal and external
conductors of the cable to release static before connecting.
Maintain Proper Ventilation
Inadequate ventilation may cause increasing of the instrument’s temperature, which will
eventually damage the instrument. So keep well ventilated and inspect the intake and fan
regularly.
Avoid Exposed Circuit or Components
Do not touch exposed contacts or components when the power is on.
Do Not Operate Without Covers
Do not operate the instrument with covers or panels removed.
Use Only the Specified Fuse.
Keep Product Surfaces Clean and Dry.
To avoid the influence of dust and/or moisture in the air, please keep the surface of the
device clean and dry.
Do Not Operate in Wet Conditions.
In order to avoid short circuiting to the interior of the device or electric shock, please do not
operate the instrument in a humid environment.
Do Not Operate in an Explosive Atmosphere.

1. Power Switch
 Power up/Power down the instrument
2. USB Host
 The analyzer can serve as a “host” device to connect external USB devices. This interface is
available for USB storage devices.
 Read and store the current instrument state or trace in the USB storage device or store the
contents currently displayed on the screen in the USB storage device in “.bmp” or “.jpg”
format.
3. Earphone Jack

CAUTION
For fear of damaging your hearing, please turn the volume down to zero and
gradually turn the volume up after putting on the earphone.
4. TG OUTPUT
 The output of the tracking generator can be connected to a receiver through a cable with an N
male connector.
CAUTION
To avoid damage to the tracking generator, the reverse DC voltage cannot
exceed 50 V
5. RF INPUT
CAUTION
To avoid damage to the instrument, for the signal input from the RF input
terminal, the DC voltage component and the maximum continuous power of
the AC (RF) signal component can not exceed 50 V and +30 dBm
respectively.

1. Handle
Pull up the handle vertically for easy carrying of the instrument. When you do not need the handle,
press it down.
2. USB Device interface
The analyzer can serve as a “slave” device to connect external USB devices. Through this
interface, a PC can be connected to control SPA-900 remotely through programming or PC
software.
3. LAN interface
Through this interface, the analyzer can be connected to your local network for remote control.
4. REF IN 10MHz
SPA-900 can use internal or external reference source.
 When a 10 MHz external clock signal is received through the [10MHz IN] connector, this
signal is used as the external reference source and “Ext Ref” is displayed in the status bar of
the user interface. When the external reference is lost, transfinite or not connected, the
instrument switches to its internal reference source automatically and “Ext Ref” on the screen
disappears.

SPA-900 Series User Manual 17
 The [10MHz IN] and [10MHz OUT] connectors are usually used to build synchronization
among multiple instruments.
5. REF OUT 10MHz
SPA-900 can use internal or external reference source.
 When internal reference source is used, the [10MHz OUT] connector can output a 10 MHz
clock signal generated by the analyzer. This signal can be used to synchronize other
instruments.
 The [10MHz OUT] and [10MHz IN] connectors are usually used to build synchronization
among multiple instruments.
6. Trigger in
In external trigger mode, the connector receives an external trigger signal through a BNC cable.
7. Security Lock Hole
If needed, you can use a security lock (buy it yourself) to lock the analyzer to a desired location.
8. Connect to AC Power Supply
The Spectrum Analyzer accept 100-240V, 50/60/440Hz AC power supply. Please use the power
cord provided as accessories to connect the instrument
