Chapter 2. Preparation for Use
2-1. Initial Inspection
Please inspect the box contents and make sure all items listed are included. Keep the
shipping box and all packing materials until the inspection of the LPT 3000 Spectrum
Analy er is complete.
Table 2-1 (below) shows all accessories offered with the LPT-6000 Spectrum Analy er.
Please contact LP Technologies Customer Support for any damaged parts, missing items
or any other issue that you may need assistance with.
To clean the unit, please use a dry or wet cloth on the surface only. Do not clean the
inside of the case.
Accessories Note:
Operation Manual CD Included in the package
Power Cable (AC Power Cable 3 Holes) Included in the package
[Table 2-1] Accessories offered with the LPT 3000 Spectrum Analy er
2-2. Requirements for Power
The LPT 3000 does not need any additional external devices, use only the power cord provided.
For more information, see Table 2-2 below.
[Table 2-2] Requirements for AC Power
Input Voltage 100 - 120 VAC ( 50 - 60 H )
To prevent an electric shock, please unplug the power cord from the main power
supply on the back of the spectrum analy er before cleaning.

Input Voltage 220 - 240 VAC ( 50 - 60 H )
Power Consumption
When Using Less than 80W
2-3. Fuse Check
When there is no spare fuse offered along with the device, the fuse to change should A
fuse should be established in the fuse holder located in the upper part of the power
switch on the back board. When replacing fuses, if no spare fuses were offered with
the unit, the replacement fuse should match the properties listed in the fuse holder
(250 VAC, 3.15 A type T 5 × 20 mm).
2-4. Power Cable
In accordance with International Safety Standards, the LPT 3000’s power cable uses 3
lines including ”Ground.” When connected to a power outlet, the cable grounds a
cabinet of the unit.
2-5. Environment Conditions
WARNING !
WARNING
!
To prevent the danger of a fire, please use only the recommended
fuses. Using a fuse with a different power rating may cause serious
damage to the spectrum analy er.
Please u
se a grounded power cable with three lines, or connect the
spectrum analy er to a protective “Ground” line. Operating the unit
without following these requirements may put you at risk of an electric
shock.
It is also important to check the source voltage
because if it exceeds the
standard recommended value, the spectrum analy er might get
damaged permanently or catch fire.

pg. 12
The LPT-6000 Spectrum Analy er will operate normally between the temperatures of 0 ℃
and 40 ℃. However, for the best performance, it is important to avoid exposing the unit
to the following conditions: severe vibration, high moisture, direct sun rays and areas
where the source voltage changes constantly.
2-6. Turning on Power
Please connect the power cord to the back panel of the LPT-6000 Spectrum Analy er,
before use, and then press the “On” button on the front panel. Allow the unit to warm up
for approximately 10 minutes before operating.
If you intend to use an external signal of 10 MH as a standard frequency, please use the 10 MH REF
IN input connector on the rear panel.
The signal level should be over -5 dBm.
WARNING !
WARNING
!
To prevent short-
circuits due to condensation. Make sure the spectrum
analy er is fully dry befo
re using it in normal conditions, after storing or
using it in low temperature environments for long periods of time.
In order to prevent the inner temperature of the unit from rising, there is
a cooling fan on the rear panel. Please, leave at least 10 cm between the
back panel and walls or other nearby devices in order to allow
proper
cooling.

make diverse set-up and arrangement by using this SYSTEM key.
PRESET key is initiali ing the analy er to an established state.
FILE key menu makes it possible to save the current trace state in a memory of the
analy er or USB flash memory, or make it to be loaded from them.
SAVE key immediately perform the currently defined saving function.
PRINT SETUP menu key makes it possible to set printing stuffs.

pg. 16
PRINT key immediately sends printing data to a printer.
8. The power button turns ON/OFF the LPT-6000 Spectrum Analy er. The Green light
indicates the unit is ON and the Red light indicates it is in a STANDBY mode. The
main power switch on the back of the unit must be ON to operate the unit. When
the unit is ON, press and hold the POWER button for 3 seconds to turn it OFF.
9. USB interface for USB Flash memory stick or USB printer cable.
10. Tracking Generator or CDMA Signal Generator input connector (Optional).
11. RF signal input connection.
A data controlling keys including a step key, a knob, and a number key pad allow the
user to change the numeric value of an active function. Turning the knob clockwise
increases values while counter-clockwise decreases values. All controlling keys can
be uses concurrently. For example, the values for the central frequency may be
adjusted by using the knob, by punching new values using the key pad or by using
the step keys to increase or decrease the values.
The knob makes it possible to successfully change values for functions such as
central frequency, reference level, and a marker location. The scope of the
adjustment will be determined by the scale of the scope of measurement. The
number key pad is used to input precise values.

3-4. Menu and Softkey Overview
There are several keys labeled (FREQUENCY, SYSTEM and MARKER…etc) on the front panel of the
LPT-6000 Spectrum Analy er designed to execute specific different functions. Pressing a front
panel key accesses a soft key menu that is located along the right side of LCD display.
Softkey menus allow access to a list of related functions to the ones obtained by pressing directly
on the front panel keys. Pressing the unlabeled keys, also called softkeys, immediately on the right
of the annotation screen will activate the functions on the softkey menu.
The function becomes active when the value of the concerned softkey menu can be
changed. Activated functions appear on the LCD screen in the active function block. For
example, pressing the FREQUENCY key will display a softkey menu of related functions on
the right of the LCD screen. Pressing the softkey corresponding to Start Freq will result in
the “Start Freq” being displayed in the active block.
Softkeys with ON and OFF allow the user to turn a function ON or OFF
Softkeys with AUTO and MAN allow the user to auto-couple or manually change values using the
