At the scene of the RF test, wireless optimization, cloth net, interfere with the application process, including
often need to test signal spectrum distribution; Field measurement needs to be portable, and Europe and
the United States of the portable spectrometer is 3 kg, field test is not convenient.
Real-time Spectrum Analysis Functions: Real-time spectrum scan SPAN/RBW/CENT/MARKER function，
MAXHLOD function，Maximum power automatic detection.，
Frequency Chromatogram Function: Show a period of time the whole time and frequency spectrum
characteristics of recycled record all spectrum distribution within 5 minutes, facilitate the frequency
interference to or launch leakage and other problems.
Heat Map Function: Spectrum shows that over a period of time spectrum overlap density contour,
repetitions show tend to be more red, more facilitate spectrum statistical characteristics of analysis for a
period of time.

Introduction to the Buttons, Ports,
and Function
Introduction to the Port and Indicator Lights
Function and Use
1.Light blue light in the normal boot, bright red when charging, the charging light green.
2.USB interface for Micro USB, the use of power is 5V / 1 A.
3.Antenna interface is the instrument for the standard SMA female head (SMA - K outside screw hole)
should be with standard male head (SMA) - J internal screw needle. Note that SMA interface normal service
life of about 1000 times (more than life, signal loss bigger or contact unstable), frequent replacement of
antenna or using radio frequency cable, SMA connector should be used the original life of interface.

User Information and Maintenance
Normal Use
Application of Environmental
Battery Matters Needing Attention
Note that large signal coverage not to exceed bid, so as not to damage the instrument to receive the
front end.
When installing the antenna or RF cable, screw thread, but do not be too hard to avoid slippery silk.
Should maintain adequate power, in order to avoid shutdown without electricity.
USB interface is fragile, plug not too hard, also avoid lateral force.
Pay attention to the storage temperature and temperature range, such as exposure do not put in the car.
Long-distance transportation should be put in boxes or suitcase, conventional scratch the LCD panel to
avoid hard objects.
It is recommended to use connector, life in order to increase the original interface.
RF connectors cleaning once every 3 month, using alcohol.
Instrument, shake the water sound or other obvious abnormal, do not use.
A thunderstorm do not test the outdoor equipment, including installation of surge arrester outdoor
equipment.
Normal warranty period is one year, such as touch, and to remove the water, not in the warranty scope.
From outdoor enter a indoor of central heating in winter, avoid instrument internal condensation, such as
condensation should be after drying in the boot.
Instrument commissioning or charging should stay away from flammable items, pay attention to
ventilation, instruments and shall not cover other things on the charger.
In order to protect the battery, please recharge instruments frequently, try not to lack of electrical
warning in charging, etc.
Ban floating for a long time, if the instrument is used for a long time to continuous charging work, please
don't please under the intermittent use of batteries in order to increase the battery life.
Instrument for a long time need not, should be charged after storage. During storage at least once every
three months with elect.
